Page 13: Ur Overview
This new generation of equipment is easily incorporated into automation systems, at both the station and enterprise levels. The GE Multilin Uni- versal Relay (UR) series meets these goals.
Page 14 The UR-series devices operate in a cyclic scan fashion. The device reads the inputs into an input status table, solves the logic program (FlexLogic equation), and then sets each output to the appropriate state in an output status table. Any result- ing task execution is priority interrupt-driven. Figure 1–3: UR-SERIES SCAN OPERATION G30 Generator Protection System GE Multilin...
Page 15: Software Architecture
Employing OOD/OOP in the software architecture of the G30 achieves the same features as the hardware architecture: modularity, scalability, and flexibility. The application software for any UR-series device (for example, feeder protection, transformer protection, distance protection) is constructed by combining objects from the various functional classes.

Page 150 Some customers prefer very low currents to display as zero, while others prefer the current be displayed even when the value reflects noise rather than the actual signal. The G30 applies a cut- off value to the magnitudes and angles of the measured currents.
Page 151: Clear Relay Records
Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user-programma- ble pushbuttons to clear specific records are typical applications for these commands. Since the G30 responds to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.
Page 152: Communications
0 ms The G30 is equipped with two independent serial communication ports. The faceplate RS232 port is intended for local use and is fixed at 19200 baud and no parity. The rear COM2 port is RS485. The RS485 port has settings for baud rate and par- ity.

Page 158 TIMEOUT: 120 s The G30 supports the Distributed Network Protocol (DNP) version 3.0. The G30 can be used as a DNP slave device con- nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the G30 maintains two sets of DNP data change buffers and connection information, two DNP masters can actively communicate with the G30 at one time.
Page 159 DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000 V on the G30 will be returned as 72). These settings are useful when analog input values must be adjusted to fit within cer- tain ranges in DNP masters.
Page 160 (for circuit breakers) or raise/lower (for tap changers) using a single control point. That is, the DNP master can operate a single point for both trip and close, or raise and lower, operations. The G30 can be configured to support paired control points, with each paired control point operating two virtual inputs.
Page 161 The G30 supports the Manufacturing Message Specification (MMS) protocol as specified by IEC 61850. MMS is supported over two protocol stacks: TCP/IP over Ethernet. The G30 operates as an IEC 61850 server. The Remote inputs and out- puts section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.
Page 162 IEC 61850 GSSE application ID name string sent as part of each GSSE message. This GSSE ID string identifies the GSSE message to the receiving device. In G30 releases previous to 5.0x, this name string was repre- sented by the setting.
Page 163 DESTINATION MAC address; the least significant bit of the first byte must be set. In G30 releases previous to 5.0x, the destination Ethernet MAC address was determined automatically by taking the sending MAC address (that is, the unique, local MAC address of the G30) and setting the multicast bit.
Page 164 The G30 has the ability of detecting if a data item in one of the GOOSE datasets is erroneously oscillating. This can be caused by events such as errors in logic programming, inputs improperly being asserted and de-asserted, or failed station components.

Page 171 The GGIO2 control configuration settings are used to set the control model for each input. The available choices are “0” (status only), “1” (direct control), and “2” (SBO with normal security). The GGIO2 control points are used to control the G30 virtual inputs.
Page 172 GGIO1 (binary status values). The settings allow the selection of FlexInteger values for each GGIO5 integer value point. It is intended that clients use GGIO5 to access generic integer values from the G30. Additional settings are provided to allow the selection of the number of integer values available in GGIO5 (1 to 16), and to assign FlexInteger values to the GGIO5 integer inputs.

Page 218 The settings specific to each winding are shown above. The following discussion is applicable to the G30 device protecting the GSU, assuming that the LV winding CTs are on the neutral side of the generator and the HV winding CTs are on the system side of the step-up delta-wye transformer. It is also assumed that CTs are differentially connected as per regular transformer differential applications, as shown in the Typical wiring, VT on the LV side of the Transformer diagram in the Applications of Settings chapter.
Page 219 The reason the source phase sequence must be stated when describing the winding phase relationships is that these rela- tionships change when the phase sequence changes. The example shown below shows why this happens, using a trans- former described in IEC nomenclature as a type “Yd1” or in GE Multilin nomenclature as a “Y/d30.” GE Multilin...
Page 220 Note that the delta winding currents leads the wye winding currents by 30°, (which is a type Yd11 in IEC nomenclature and a type Y/d330 in GE Multilin nomenclature) which is in disagreement with the transformer nameplate. This is because the physical connections and hence the equations used to calculate current for the delta winding have not changed.
Page 221 CTs or tapped relay windings were used to minimize this error. The G30 automatically corrects for CT mismatch errors. All currents are magnitude compensated to be in units of the CTs of one winding before the calculation of differential and restraint quantities.
Page 222 The G30 performs this phase angle compensation and zero sequence removal automatically, based on the settings entered for the transformer. All CTs are connected Wye (polarity markings pointing away from the transformer). All currents are phase and zero sequence compensated internally before the calculation of differential and restraint quantities.

Figure 5–40: UR ARCHITECTURE OVERVIEW The states of all digital signals used in the G30 are represented by flags (or FlexLogic operands, which are described later in this section). A digital “1” is represented by a 'set' flag. Any external contact change-of-state can be used to block an ele- ment from operating, as an input to a control feature in a FlexLogic equation, or to operate a contact output.

The most dependable protection of the initiating contact is provided by directly measuring current in the tripping circuit, and using this parameter to control resetting of the initiating relay. This scheme is often called trip seal-in. This can be realized in the G30 using the FlexLogic operand to seal-in the contact output as follows: CONT OP 1 ION “Cont Op 1"...
Page 360 5 SETTINGS The G30 latching output contacts are mechanically bi-stable and controlled by two separate (open and close) coils.

LAN environment. Actual MMS protocol services are mapped to IEC 61850 abstract ser- vices in IEC 61850-8-1. The G30 relay supports IEC 61850 server services over TCP/IP. The TCP/IP profile requires the G30 to have an IP address to establish communications. These addresses are located in the ...
Page 586: File Transfer By Iec 61850
APPENDIX C C.1.3 FILE TRANSFER BY IEC 61850 The G30 supports file transfer by IEC 61850. The approach is as follows, using the SISCO AX-S4 61850 client software as an example. In the AX-S4 61850 Explorer window, click the Tools menu and access the SISCO File Transfer Utility.
Page 587: Server Data Organization
C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the G30 to provide access to as many 128 digital status points and associated time- stamps and quality flags. The data content must be configured before the data can be used. GGIO1 provides digital status points for access by clients.
Page 588: Mmxu: Analog Measured Values
C.2.6 MMXU: ANALOG MEASURED VALUES A limited number of measured analog values are available through the MMXU logical nodes. Each MMXU logical node provides data from a G30 current and voltage source. There is one MMXU available for each configurable source (programmed in the ...
Page 589 The protection elements listed above contain start (pickup) and operate flags. For example, the start flag for PIOC1 is PIOC1.ST.Str.general. The operate flag for PIOC1 is PIOC1.ST.Op.general. For the G30 protection elements, these flags take their values from the pickup and operate FlexLogic operands for the corresponding element.
Page 590: Server Features And Configuration
C.3.4 LOGICAL DEVICE NAME The logical device name is used to identify the IEC 61850 logical device that exists within the G30. This name is composed of two parts: the IED name setting and the logical device instance. The complete logical device name is the combination of the two character strings programmed in the settings.
Page 591: Logical Node Name Prefixes
A built-in TCP/IP connection timeout of two minutes is employed by the G30 to detect ‘dead’ connections. If there is no data traffic on a TCP connection for greater than two minutes, the connection will be aborted by the G30. This frees up the con- nection to be used by other clients.
Page 592: Generic Substation Event Services: Gsse And Goose
MAC address for GSSE messages. If GSSE DESTINATION MAC ADDRESS a valid multicast Ethernet MAC address is not entered (for example, 00 00 00 00 00 00), the G30 will use the source Ether- net MAC address as the destination, with the multicast bit set.
Page 593 The G30 has the ability of detecting if a data item in one of the GOOSE datasets is erroneously oscillating. This can be caused by events such as errors in logic programming, inputs improperly being asserted and de-asserted, or failed station components.
Page 594 REMOTE IN 1 ITEM item to remote input 1. Remote input 1 can now be used in FlexLogic equations or other settings. The G30 must be rebooted (control power removed and re-applied) before these settings take effect. The value of remote input 1 (Boolean on or off) in the receiving device will be determined by the GGIO1.ST.Ind1.stVal value in the sending device.
Page 595: Ethernet Mac Address For Gsse/Goose
GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the G30 is configured to use an automated multicast MAC scheme. If the G30 destination MAC address setting is not a valid multicast address (that is, the least significant bit of the first byte is not set), the address used as the destina- tion MAC will be the same as the local MAC address, but with the multicast bit set.
Page 596: Iec 61850 Implementation Via Enervista Ur Setup
An ICD file is generated for the G30 by the EnerVista UR Setup software that describe the capabilities of the IED. The ICD file is then imported into a system configurator along with other ICD files for other IEDs (from GE or other ven- dors) for system configuration.
Page 597: Configuring Iec 61850 Settings
Transmission GOOSE dataset may be added or deleted, or prefixes of some logical nodes may be changed. While all new configurations will be mapped to the G30 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.
Page 598: About Icd Files
Although configurable transmission GOOSE can also be created and altered by some third-party system con- figurators, we recommend configuring transmission GOOSE for GE Multilin IEDs before creating the ICD, and strictly within EnerVista UR Setup software or the front panel display (access through the Settings > Product Setup > Com- munications >...

The EnerVista UR Setup will prompt to save the file. Select the file path and enter the name for the ICD file, then click OK to generate the file. The time to create an ICD file from the offline G30 settings file is typically much quicker than create an ICD file directly from the relay.

Right-click anywhere in the files panel and select the Import Contents From SCD File item.
Page 606 The software will open the SCD file and then prompt the user to save a UR-series settings file. Select a location and name for the URS (UR-series relay settings) file. If there is more than one GE Multilin IED defined in the SCD file, the software prompt the user to save a UR-series set- tings file for each IED.
