When a settings file is transferred to a G30 device, the date, time, and serial number of the G30 are sent back to EnerVista UR Setup and added to the settings file on the local PC. This infor- mation can be compared with the G30 actual values at any later date to determine if security has been compromised.
Page 123 With respect to the above diagram, the traceability feature is used as follows. The transfer date of a setting file written to a G30 is logged in the relay and can be viewed via EnerVista UR Setup or the front panel display. Likewise, the transfer date of a setting file saved to a local PC is logged in EnerVista UR Setup.

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 167 ETHERNET NETWORK TOPOLOGY The G30 has three Ethernet ports. Each Ethernet port must belong to a different network or subnetwork. Configure the IP address and subnet to ensure that each port meets this requirement. Two subnets are different when the bitwise AND oper- ation performed between their respective IP address and mask produces a different result.

The delay in switching back ensures that rebooted switching devices connected to the G30, which signal their ports as active prior to being completely functional, have time to completely initialize themselves and become active. Once port 2 is active again, port 3 returns to standby mode.

Page 181 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 182 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 183 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 184 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 246 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 247 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 248 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 249 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 250 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.

8.1.1 CURRENT DIRECTIONAL PROTECTION For better security, the G30 uses the current directional protection principle to dynamically supervise the main current differ- ential function. The directional principle is in effect permanently for low differential currents (region 1 in the Two Regions of Differential Characteristic figure) and is switched on dynamically for large differential currents (region 2 in the same figure) by the saturation detector (see the Saturation Detector section) upon detecting CT saturation.

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 622: 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 623: 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 624: 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 625 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 626: 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 627: 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.

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 629 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 630 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 631: 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 632: 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 633: 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 634: 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 642 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.
