    As such, no further functional tests are required. The C70 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the Relay Self-tests section in chapter 7). However, it is recommended that C70 maintenance be scheduled with other system maintenance.

    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 C70 applies a cut- off value to the magnitudes and angles of the measured currents.

    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 C70 responds to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.

    TIMEOUT: 120 s The C70 supports the Distributed Network Protocol (DNP) version 3.0. The C70 can be used as a DNP slave device con- nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the C70 maintains two sets of DNP data change buffers and connection information, two DNP masters can actively communicate with the C70 at one time.

  • Page 160

    DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000 V on the C70 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.

    The C70 supports the Manufacturing Message Specification (MMS) protocol as specified by IEC 61850. MMS is supported over two protocol stacks: TCP/IP over Ethernet.

    LAN environment. Actual MMS protocol services are mapped to IEC 61850 abstract ser- vices in IEC 61850-8-1. The C70 relay supports IEC 61850 server services over TCP/IP. The TCP/IP profile requires the C70 to have an IP address to establish communications. These addresses are located in the ...

    C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the C70 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 605: C.2.6 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 C70 current and voltage source. There is one MMXU available for each configurable source (programmed in the ...

    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 C70 protection elements, these flags take their values from the pickup and operate FlexLogic operands for the corresponding element.

    C.3.4 LOGICAL DEVICE NAME The logical device name is used to identify the IEC 61850 logical device that exists within the C70. 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 608: C.3.6 Logical Node Name Prefixes

    A built-in TCP/IP connection timeout of two minutes is employed by the C70 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 C70. 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 C70 will use the source Ether- net MAC address as the destination, with the multicast bit set.

  • Page 610

    The C70 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 611

    REMOTE IN 1 ITEM item to remote input 1. Remote input 1 can now be used in FlexLogic equations or other settings. The C70 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 612: C.4.5 Ethernet Mac Address For Gsse/goose

    GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the C70 is configured to use an automated multicast MAC scheme. If the C70 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 613: C.5.1 Overview

    An ICD file is generated for the C70 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 614: C.5.2 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 C70 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.

  • Page 615: C.5.3 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 >...

    Furthermore, it defines the capabilities of an IED in terms of communication services offered and, together with its LNType, instantiated data (DO) and its default or configuration values. There should be only one IED section in an ICD since it only describes one IED. C-14 C70 Capacitor Bank Protection and Control System GE Multilin...

    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 C70 settings file is typically much quicker than create an ICD file directly from the relay.

    Like ICD files, the Header node identifies the SCD file and its version, and specifies options for the mapping of names to signals.

Right-click anywhere in the files panel and select the Import Contents From SCD File item.

    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.
