                 DGT Distributed Generation Trip
                 Control System

                 Chapter 1: Introduction

                              Introduction




                 Overview
                              The DGT Distributed Generation Control System is a wireless communication system
                              designed to transfer Trip Status signals between a Utility’s substation or recloser site and
                              Distributed Generation locations. The DGT system supports point to multipoint
                              communication over distances up to 30 miles and accommodates up to 6 Distributed
                              Generation locations. There are three main products in a DGT System, the DGT-U, DGT-D
                              and DGT-R
                              DGT-U is installed by a Utility at the substation or recloser. It transfers trip signals to
                              remote DG sites and receives status notification back from each, after a trip operation has
                              been completed.
                              DGT-R is a repeater unit installed by the Utility at or near the Utility substation, to
                              coordinate wireless communication between the DGT-U/DGT-R and the DGT-D(s).
                              DGT-D is installed at the Distributed Generation site. It receives the trip signal over-the-air
                              from the DGT-U and outputs the status to the user’s breaker device. The DGT-D also
                              accepts a connection from the user’s breaker equipment that confirms the trip status back
                              to the DGT-U.
                              At the core of all DGT units is a wireless DGT transceiver. The DGT transceivers are
                              frequency hopping; spread spectrum radios designed for license-free operation in the 902-
                              928 ISM band. The 902-928 ISM band is license-free throughout North America. The DGT
                              transceivers employ the latest Digital Signal Processing (DSP) technology to provide highly
                              reliable long distance communication.


                 Cautions and warnings
                              Before attempting to install or use this device, it is imperative that all caution and danger
                              indicators in this manual are reviewed to help prevent personal injury, equipment damage,
                              or downtime. The following icons are used to indicate notes, cautions, and dangers.

                                 In Figure 2, DGT-U units installed at the Utility Substation and Recloser sites continuously
                                 monitor the trip status and transmit that status every 28 to 56 milliseconds to DGT-D units
                                 installed at the Distributed Generation sites. At the DGT-D locations the trip status is wired
                                 into breaker device. An auxiliary contact from the breaker is wired back into the DGT-D.
                                 The DGT-D units continuously monitor the status of the auxiliary contact and transmit that
                                 status every 28-56 milliseconds back to the DGT-U units constantly confirming current
                                 status. All communication is coordinated through the DGT-R Unit in order to achieve
                                 maximum range.
                                 If a trip condition is detected by the Utility’s equipment, the trip status is energized at the
                                 DGT-U. When the DGT-D units receive the energized trip status, the output status will
                                 disconnect the Breaker device at the Distributed Generation site. The status of auxiliary
                                 contact from the breaker is also energized and transmitted back to the DGT-U thereby
                                 confirming that the Trip has occurred.

CHAPTER 1: INTRODUCTION                                                                                                                           OVERVIEW



                              The entire round trip time from trip initiation at the substation into the DGT-U to
                              confirmation from the DGT-D occurs in under 150 milliseconds. The integrity of the Trip
                              Status state is maintained through the use of a 32-bit CRC calculation. The CRC prevents
                              the erroneous or malicious manipulation of the Trip Status so that only true data is acted
                              upon. Additional security precautions ensure that only authorized DGT-D devices are able
                              to wireless achieve association with a Utility’s DGT-U and DGT-R devices, so that the
                              integrity of each DGT system is maintained.


                 Description of the DGT system units
                              The DGT-U, DGT-R and DGT-D, are completely packaged units that includes the
                              appropriate DGT radio transceiver, power supply, necessary input and output terminations,
                              antenna jumper cable and lightning protection contained in a weather resistant, pad
                              lockable enclosure. The only connections required are for primary power, the external
                              antenna cable, and wiring to the external equipment. All of these wiring connections are
                              made within the enclosure leaving no connections exposed to weather. DGT units are
                              designed to be installed in wall-mount or pole-mount configurations. All DGT components
                              are housed in a NEMA-approved enclosure measuring 13.75 inches high x 11.85 inches
                              wide x 6.5 inches deep (35cm x 30.1cm x 16.5cm).
                              There are internal variations in the components contained in a DGT-U, DGT-D or DGT-R.
                              These variations are shown in Figures 3 through 5

MECHANICAL INSTALLATION                                                                        CHAPTER 2: INSTALLATION



               Installation Considerations
                          For a successful installation, careful thought must be given to selecting the proper site for
                          the DGT-D and its antenna system. The location must be able to support antenna
                          mounting at a height and in a direction that provides an unobstructed radio signal
                          transmission path to associated DGT sites.
                          The antenna must aim at the antenna located at your Utility’s DGT-R. The Utility will
                          provide you with the direction and coordinates to aim the antenna. In addition, the
                          antenna must be at a suitable height to achieve radio association with the Utility’s
                          equipment. DGT-D equipment is offered with a number of standard options for antenna
                          feedline lengths. Select the feedline length necessary to connect the Yagi antenna to the
                          DGT Unit.
                          Radio signals travel primarily by line-of-sight, and obstructions between the transmitting
                          and receiving devices will affect system performance. If you are not familiar with the
                          effects of terrain and other obstructions on radio transmission, please contact Multilin for
                          information on arranging a Radio Path Analysis or Site Survey. In addition, the information
                          below will provide helpful background.
                          TERRAIN AND SIGNAL STRENGTH
                          A line-of-sight transmission path between the DGT-D sites is highly desirable and provides
                          the most reliable communications link. A line-of-sight path is achieved by mounting the
                          antenna on a tower, pole or other elevated structure that raises it to a height sufficient to
                          clear surrounding terrain and other obstructions.
                          The importance of a clear transmission path relates closely to the distance between the
                          DGT-U and the Utility’s DGT-R. If that distance is limited, for example up to 3 miles (4.8 km),
                          then some obstructions in the communications path can usually be tolerated with minimal
                          impact. For longer distances, any substantial obstruction in the communications path
                          could compromise performance or block communications entirely
                          CONDUCTING A SITE SURVEY
                          There must be no doubt about the radio path and antenna height needed for your DGT site
                          to associate with other DGT stations. Planning and testing is necessary before a
                          permanent installation is begun. This is done through a path analysis and site survey
                          conducted by a qualified professional. A site survey gathers actual site information and
                          summarizes the installation factors specific to a given site. A computer path analysis
                          based upon the latitude and longitude coordinates of the DGT site assesses factors such
                          as terrain, distance, transmitter power, and receiver sensitivity, which are necessary to
                          predict the performance of the DGT installation.


               Mounting the enclosure
                          There are two basic mounting arrangements for the DGT: wall mount or pole mount.
                          Methods for mounting the unit in both of these configurations follow. When planning the
                          installation, refer to the Dimensions section above, which shows the mounting dimensions
                          of the DGT Assembly.
                          The steps below describe mounting of the DGT unit to a wall or other flat surface. Ordinary
                          wood screws (with flat washers) can be used for mounting to a wooden surface. If it is to be
                          mounted to a drywall, masonry or other non-wooden surface, suitable fasteners will be
                          required that can support the weight of the unit.
                          WALL MOUNTING
                          To wall mount the unit, follow these instructions
                          1.   Hold the unit up to the wall in the desired mounting position. Have an assistant mark
                               the four mounting holes (see Dimensions section above) with a pencil or marker.

CHAPTER 2: INSTALLATION                                                                        MECHANICAL INSTALLATION



                              2.   Prepare the mounting surface for the fasteners to be used. (If using lag screws, a small
                                   pilot hole at each mark will allow easier starting of the screw.)
                              3.   Insert the 4 mounting screws and tighten them securely. Do not over-tighten.
                              POLE MOUNTING
                              Standard pole mounting requires the use of two pole-mount adapters (P/N 82-1743A01).
                              These brackets must first be bolted to the DGT enclosure. The complete assembly can then
                              be mounted to a wooden utility pole with two lag screws or with two long bolts that extend
                              through the pole. (Threaded rod can also be used for through-the-pole mounting.) In either
                              case, it is important to use flat washers with the attaching hardware (fasteners are not
                              supplied).
                              To pole mount the unit, follow these instructions:
                              1.   Attach the two pole-mount adapter brackets to the DGT enclosure with four 10-32
                                   screws. The screws must be no longer than 3/8" (9.5 mm). Longer screws will damage
                                   the enclosure
                              2.   With the help of an assistant, position the DGT enclosure on the pole at the desired
                                   mounting point.
                              3.   Install the attaching hardware (with flat washers) in the center hole of the two
                                   brackets.
                              4.   Tighten the fasteners securely, but do not over-tighten.

                          This section describes the connection of external cabling to the DGT-D Assembly. The
                          figures below show overall views of the connection points for all external cabling and
                          wiring. Subsequent illustrations show more detailed views of power connections as
                          required.
                          Route the power and I/O signal wiring through the weathertight bushing on the bottom of
                          the enclosure. Do not tighten it until all cabling has been installed. All user connections for
                          power and signal wiring are made to the terminal block.

CHAPTER 2: INSTALLATION                                                              ANTENNA AND FEEDLINE INSTALLATION




                 Antenna and feedline installation
                              DGT units are ordered with an antenna and feedline package, ready for installation at the
                              station site. A number of standard feedline lengths are available. The length necessary to
                              connect the station antenna to the DGT is determined during the site survey.
                              Antennas must be mounted in a location providing an unobstructed radio signal path to
                              associated stations. Radio signals at UHF travel primarily by line-of-sight, and obstructions
                              between the transmitting and receiving devices will affect system performance. A line-of-
                              sight path is achieved by mounting the DGT antenna on a pole, tower, or other elevated
                              structure that raises it to a height sufficient to clear surrounding terrain and other
                              obstructions.
                              The importance of a clear transmission path relates closely to the distance between DGT
                              units. If that distance is limited, for example up to 4.8 km (3 miles), then some obstructions
                              in the communications path can usually be tolerated with minimal impact. For longer
                              distances, any substantial obstruction in the communications path could compromise
                              performance or block communications entirely. If you are not familiar with the effects of
                              terrain and other obstructions on radio transmission, please contact Multilin for
                              information on arranging a Radio Path Analysis or Site Survey
                              ANTENNA INSTALLATION - DGT-U and DGT-D
                              The antenna supplied with DGT-D and DGT-U units is a directional Yagi type that must be
                              properly aimed at the DGT-R site with which it will communicate.
                              Follow these steps to install the antenna at DGT-D and DGT-U sites:
                              1.   Mount the antenna securely to a pole or other support structure with the hardware
                                   provided.
                              2.   Aim the antenna directly at the DGT-R site with which the unit will communicate. (The
                                   direction of maximum transmission/reception is opposite the antenna mounting
                                   bracket).
                              3.   Secure the coaxial cable to the mounting pole and route it to the DGT enclosure.
                              4.   Connect the antenna cable to the Type-N connector at the bottom of the DGT
                                   enclosure. Tighten the connector securely.
                              ANTENNA INSTALLATION - DGT-R
                              DGT-R (Repeater) units are furnished with an omni-directional antenna that does not
                              require aiming. However, it is still important to mount the antenna at a height that allows
                              an unobstructed path to the stations it will serve. Omni-directional antennas are typically
                              mounted to a pole.
                              Follow these steps to install the antenna at DGT-R sites:
                              1.   Secure the antenna to the mounting pole or other support structure with the
                                   hardware provided.
                              2.   Connect a low-loss coaxial cable to the antenna and tighten the connector securely.
                              3.   Secure the coaxial cable to the mounting pole and route it to the DGT enclosure.
                              4.   Connect the antenna cable to the Type-N connector at the bottom of the DGT
                                   enclosure. Tighten the connector securely.

ANTENNA AND FEEDLINE INSTALLATION                                                          CHAPTER 2: INSTALLATION



               Maintaining regulatory compliance (RF output power)
                           The transceiver is normally supplied from the factory set for a nominal +30 dBm RF power
                           output; this is the maximum transmitter output power allowed under FCC/IC rules. The
                           power must be decreased from this level if the antenna system gain exceeds 6 dBi. The
                           maximum allowable RF level from the transceiver is dependent on the gain of the antenna
                           and feedline loss. In all cases, the maximum EIRP from the antenna must not exceed 36
                           dBm. Contact GE Multilin if assistance is required in determining the maximum output
                           power setting.
                           SAFETY / EARTH GROUNDING
                           DGT equipment is equipped with an internal surge suppression module to protect against
                           nearby lightning discharges or spikes on the antenna feedline. To minimize the chances of
                           lightning and surge damage, a good safety ground is required. This ground must bond the
                           antenna system, the DGT unit, power supply, and all connected data equipment to a
                           single-point ground.
                           Equipment grounds should be bonded together and connected to the facility’s main
                           ground system for primary power. The objective is to create a single-point ground system,
                           keeping all grounds leads as short as possible.

                              8.   There are some extra features in the Online Window that you can find quite useful
                                   when dealing with the DGT devices:
                              •    Diagnostic – gets current settings from the device. These settings can be stored in a
                                   text file and, in case of necessary, sent later to the technical support team.
                              •    Status – gets the synchronization status of the device.
                              •    Logout – forces system to logout.
                              9.   If you double click upon Diagnostics node in the Online window, the next window will
                                   appear:

                                  Pressing the Save to File button saves the Diagnostics information in a text file, which,
                                  if necessary, can be sent to a technical support team for analysis.
                           10. If you double click upon Status node, the next window will appear:




                                  The Status window continuously shows the synchronization state of the DGT system.

                           11. To log out of EnerVista DGT-DG. Click on Logout. Once you log out, you have to press
                               the Quick Connect button to log back in. This feature is generally used when a
                               situation arises that necessitates a formal logout. Any accidental disruption
                               (computer breakdown for example) of the system will NOT log you out of the system; it
                               will still be active after the disruption is corrected. Manual logout avoids this. Under
                               normal operating conditions, the system will automatically log out when it has been
                               inactive for 5 minutes (unchangeable default).

                                As we have reached this point we have created an System file with all the appropriate
                                information and now we are ready to go further for configuring DGT System -
                                generate Settings files (based on the System file) and upload them to the appropriate
                                devices.


                DGT-Utility configuration - Creating and uploading a Settings File
                            The Settings File is part of the whole DGT System configuration, and is related to a
                            dedicated device within the system. The important things to know about the Settings File
                            are:
                            •   The Settings File for a particular device should be generated or updated before being
                                uploaded to the device.
                            •   The Settings File can be generated automatically (the system will do it for you) or
                                manually (by user request). In the latter case, the user can specify explicitly which file
                                name he/she wants to assign to it.
                            •   Each Settings File contains the device number in an encrypted format, so this file can
                                be correctly uploaded to the device only with the exact same number. If not, an error
                                message will appear during the upload process.
                            To create Settings Files, follow the steps below:
