Chapter 2: Product description

Product description

This chapter outlines the product, order codes, and specifications.

Product descriptionThe Multilin DGPR is a pre-designed retrofit solution for the Digital Generator Protection (DGP) Relay. The DGPR is a one-to-one replacement of a DGP relay and includes a G60 Generator Protection System, which is part of the GE Universal Relay (UR) family of products.

The DGPR is a microprocessor-based digital relay system that uses waveform sampling of current and voltage inputs to provide protection, control, and monitoring of generators. It can be used with any size of generator and is well-suited for large hydro, gas, and steam turbine generators.

One of the benefits of the DGPR is ease of wiring. You simply disconnect the wires from the back of the DGP and connect them to the back of the DGPR. The DGPR itself is pre-wired for the connections with the integrated G60.

Figure 1: DGP (left) replaced by DGPR (right)

Wiring diagramsA typical wiring diagram for the G60 follows.

Wiring diagrams of typical AC and DC schemes also follow.

Because the connections to the DGPR are the same as the DGP, meaning you disconnect the wires from the DGP and connect them to the same terminal blocks on the DGPR. Except for the power supply alarm connections, see diagram GPRP00002 for details.

Difference between CT connections of DGP and DGPRThe DGPR is a retrofit solution for the DGP and although the attempt was made to maintain as much similarity as possible, there are some differences, such as the CT connection shown as follows.

Figure 12: Typical CT connections

As both the DGPR and DGP use residual connections, the DGP uses a hard-wire approach to sum all of the current in INS or INR. In the DGPR, the 51N element is connected in the common neutral connection of the current transformer. This is the most common connection arrangement. On four-wire circuits, a fourth current transformer is connected in the neutral circuit as shown (dotted line).



Figure 13: DGP 50/51N element

The protection response to the residual current is

In = 3I_0 = Ia + Ib + Ic Eq. 1

For those models that uses Core Balance (Zero Sequence) CT only in the DGP relay, where the conductor cables pass through the center hole of the core balance CT, the GE application team can verify customer requirements and modify the default configuration of the DGPR. This type of connection is considered a custom order.

Figure 14: Custom configuration

CT inputs system sideThe DGPR takes four current inputs in the system side. BH1, BH3, and BH5 are for current inputs, while BH2, BH4, and BH6 are for common return. BH7-BH8 was used for INS in the DGP, but they are not used in the DGPR.

Figure 15: DGPR CT connections system side



CT inputs neutral sideThe DGPR takes four current inputs in the neutral side. AH1, AH3, and AH5 are for current inputs, while AH2, AH4, and AH6 are for common return. AH7-AH8 was used for INR in the DGP, but they are used for 51G or GPM connection in the DGPR.

Figure 16: DGPR CT connections neutral side

Voltage inputsThe DGPR takes four voltage inputs. The DGPR phase voltage inputs can be WYE or DELTA and are derived from the generator terminal voltage. Vx is derived from the generator neutral grounding transformer.

Do not switch the switches under load or similar on units. Do not touch any open blade when the system is energized. Death or serious injury can result.


INSTALL HARDWARE CHAPTER 3: INSTALLATION

Install hardwareYou rack-mount the unit, connect the wires for currents and voltages, and connect the power source.

The DGPR panel is accessible from the front. The G60 device, pushbuttons, and test switches are mounted on the front. The terminal blocks for connections are mounted at the back.

The figure shows the front and back of the unit with the cover and wires installed.

Figure 19: Cover installed and unit wired

Perform installation without power to the DGP and DGPR, else death or serious injury can result.

Leave the DGP installed, including all wire connections, before installing the DGPR. This is a one-to-one replacement. As a result, each connection at the back of the DGP goes into the same terminal block on the DGPR, except for power supply alarm connections.

Mount the unitThe DGPR is installed into a 19-inch rack. The process is as follows:

• Mount in rack using tools provided

• Screw in rack

• Attach Lexan cover

Two people are required to mount the unit.

To mount the unit:

1. With the power off to the DGP, remove the DGP and place it on a cart beside the rack, leaving the wires connected. The DGPR is to be installed into the DGP slot on the rack.

2. Decide which two holes are to be used on the 19-inch rack for the DGPR to coincide with the pins of the installation tools in holes E and F shown. Mark the two holes on the rack.

3. Prepare to lift the unit as follows. One installer takes one of the installation tools and inserts it into hole E (see next figure). The other installer inserts the other installation tool into hole F.

CHAPTER 3: INSTALLATION INSTALL HARDWARE


Figure 20: Preparing to lift the DGPR unit

4. Lift the unit with each installer holding the bended bottom surface of the DGPR.

5. Insert the two pins of the installation tools into the required holes on the 19-inch rack. Leave the installation tools inserted.

Figure 21: Inserting the installation tool pins in the rack

6. Check that the other mounting holes of the DGPR align with the holes in the rack.

7. Install four screws in holes A, B, C, and D.

8. Remove the installation tools, and install two screws in holes E and F (see next figure).



Figure 22: Rear view with screw installed

9. Apply two nuts in locations G and H.

10. Install the two screw posts for the Lexan cover on the test switch faceplate.

Figure 23: Screw locations for Lexan cover

11. Install the Lexan cover (GE part number 1502-0052), aligning the thumb nuts to the installed screws.

12. Hand-tighten the thumb nuts to secure the Lexan cover. See the next figure for the complete installation.



Figure 24: Cover installed



Connect the wiresThe first step in wiring involves connecting the currents, voltages, digital inputs, and digital outputs to terminals blocks at the back of the switch panel as per the DGPR wiring diagram. The digital inputs and outputs are also referred to as contact inputs and outputs.

There are eight 14 pole-terminal blocks at the back of the unit, designated as AE, AF, AG, AH, BE, BF, BG, and BH. The current transformer (CT) and voltage transformer (VT) wires are connected to the bottom two rows. The contact inputs and outputs are connected to the top two rows.

Figure 25: DGPR back panel connections

To connect the wires:

1. With power off to the DGP, take the CT and VT inputs on the DGP and connect them to the same terminal blocks AH and BH on the outside at the back the DGPR chassis. Each connection on the DGP goes in the same terminal block on the DGPR. Use wiring diagram DWG # GPRP000002 as a reference.

2. Take the digital inputs and outputs from the DGP and connect them to terminal blocks AE, AF, AG, BE, BF, and BG on the outside at the back of the DGPR chassis. Each connection on the DGP goes in the same terminal block on the DGRP. Refer to a wiring diagram. Note that the power connections also go into AG and BG; move them now after reading the next section or wait.



Connect the power supplyThe DGPR has redundant power supply. The right-most module at the back of the G60 (slots A and B) is the main power supply module. The left-most module is the redundant power supply module (slots W and X). Power is connected and grounded on the back of the G60 at the top right.

The DGPR has a grounding bar. Eight connection points ground each of the eight G60 modules, including the two power supplies. These eight connections points connect the G60 to the DGPR chassis. They are installed in the factory. In addition, the DGPR grounding bar must be connected directly to the generator protection panel grounding bus.

Figure 26: Connecting ground to top of chassis (six of eight connections shown, installed in factory)

To ground the DGPR:

1. Using a wire, connect the DGPR ground bus to the panel/rack grounding bus. The recommended minimum wire size for the connection is 6 AWG. For example, attach the wire to the "ground connection point" shown in the previous figure.

The power connects to the terminal blocks on the back of the DGPR. The connections are same as on the DGP.

To connect the power supply:

1. With power off to the DGP, take the power connections from the back of the DGP and connect them to the back of the DGPR. That is, connect the control power supplied to the relay to terminal block AG1 (+) and AG2 (-) for Power Supply # 1 and BG13 (+) and BG14 (-) for Power Supply # 2. See Figure 27.

If there is only one power source, install jumpers between AG1-BG13 (+) and AG2-BG14 (-) and connect the power to AG1 (+) and AG2 (-). See Figure 28.


ACTIVATE G60 RELAY CHAPTER 3: INSTALLATION

Figure 27: DGPR two power source connection

Figure 28: DGPR single power source connection

Consider relay contacts unsafe to touch when the unit is energized. Death or serious injury can result from touching live relay contacts.

Do not switch the switches under load or similar on units. Do not touch any open blade when the system is energized. Death or serious injury can result.

Activate G60 relayBefore or after installing the EnerVista UR Setup software, the G60 unit needs to be activated by setting it to "Programmed" mode. This can be done on the front panel of the G60 or in the software. The path is Settings > Product Setup > Installation > Relay Settings on the front panel. The path is Settings > Product Setup > Installation in the software. For more information, see the procedure in the G60 instruction manual.

Install softwareCommunication with the DGPR unit can be done via the front panel and by a computer with software. Typically, the front panel is used in the field, and a remote computer is used in a substation or other office.

The G60 includes EnerVista UR Setup software that is installed on a computer. Follow the procedure in the G60 instruction manual to install the software. There is no additional software for the DGPR or its test switches.

CHAPTER 3: INSTALLATION CONNECT G60 RELAY


Connect G60 relayThe G60 is connected typically to a network for communication with other devices, for example using the Ethernet port. It also connects to a computer running the EnerVista software, either on-site using the RS232 port or remotely using the Ethernet port, for example.

There are three ways to connect the G60:

• RS232 port

• Ethernet port

• RS485 port

Connect the computer/network and relay now using one of the three connection options.

Connect using RS232 portThe G60 has a nine-pin RS232 serial port on its front panel, which makes it useful for connecting the computer to the device in the field.

Figure 29: RS232 port on G60 front panel

Cabling for the RS232 port is shown in the following figure for both nine-pin and 25-pin connectors. The baud rate for this port can be set, with a default of 115200 bps.


CONNECT G60 RELAY CHAPTER 3: INSTALLATION

Figure 30: RS232 faceplate port connection

Connect using Ethernet portThe G60 is connected typically with other devices and to the computer by Ethernet. There is an Ethernet port on the CPU module at the back of the unit.

Figure 31: Port locations on rear of G60

CHAPTER 3: INSTALLATION IRIG-B


Connect using RS485 portThe rear of the G60 has a serial RS485 port that can also be used for communication. It is on the CPU module. See the G60 instruction manual for more information.

RS485 data transmission and reception are accomplished over a single twisted pair with transmit and receive data alternating over the same two wires. Through the use of these ports, continuous monitoring and control from a remote computer, SCADA system, or power line carrier (PLC) is possible. To minimize errors from noise, the use of shielded twisted pair wire is recommended. Correct polarity must also be observed.

IRIG-BIRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices. The IRIG-B code allows time accuracies of up to 100 ns. Using the IRIG-B input, the G60 operates an internal oscillator with 1 µs resolution and accuracy. The GE MultiSync 100 1588 GPS Clock as well as third-party equipment are available for generating the IRIG-B signal; this equipment can use a global positioning system (GPS) satellite system to obtain the time reference so that devices at different geographic locations can be synchronized.

You can optionally use IRIG-B for timing. See the G60 instruction manual for information.

With installation of the DGPR complete, use the G6 instruction manual to program the settings.
