  • 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 L60 Line Phase Comparison System GE Multilin...
  • Page 15: Software Architecture

    Employing OOD/OOP in the software architecture of the L60 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.

The term “mixed-excitation”, when applied to phase compari- son, describes a scheme that first mixes different sequence quantities in a given proportion and phase angle, then performs a phase-comparison based on this mix.
  • Page 524 Different methods can be used. The L60 allows the customer to check and set phase delay without using an oscilloscope and by means of FlexLogic oper- ands and applying the corresponding current to both relays. Oscillography shows the time difference (including PLC delay and line propagation time) between local and remote signals.

    10.2.8 SINGLE-POLE TRIPPING APPLICATIONS The L60 provides functionality for single-pole tripping from 87PC, distance functions, or instantaneous overcurrent ele- ments via the trip output element. 87PC can detect internal faults on the line but not faulted phases, since the phase cur- rents are combined in one quantity.
  • Page 531: Phase Distance

    The current supervision alone would not prevent maloperation in such circumstances. It must be kept in mind that the fuse failure element provided on the L60 needs some time to detect fuse fail conditions. This may create a race between the instantaneous zone 1 and the fuse failure element. Therefore, for maximum security, it is recommended to both set the current supervision above the maximum load current and use the fuse failure function.

    Similar to the phase fault case, a zone 3 element must be time coordinated with timed clearances on the next section. 10-10 L60 Line Phase Comparison System GE Multilin...
  • Page 533: Pott Signaling Scheme

    This situation is encountered when it is desired to account for the zero sequence inter-circuit mutual cou- pling. This is not a problem for the ground distance elements in the L60 which do have a current reversal logic built into their design as part of the technique used to improve ground fault directionality.

    It is strongly rec- ommended to use a power system simulator to verify the reach settings or to use an adaptive L60 feature for dynamic reach control.
  • Page 535: Understanding L60 Oscillography

    L60 relay incorporates standard analog phase comparison principles. The L60 oscillography allows customer to observe not only AC waveforms and 87PC operate signals, but all details of compos- ite signal forming, fault detector operation, input and output processing, squares forming, coincidence detection, and inte- gration of the signal.
  • Page 536: Two Breaker Configuration

    10.5.2 TWO BREAKER CONFIGURATION The L60 has extra security when 2 CTs are brought into the relay individually and summed internally. Two currents are pro- cessed separately to derive the operating signal for each breaker, which is then used for fault detectors and the forming of positive and negative squares.

    The enhanced faceplate can be opened to the left, once the thumb screw has been removed, as shown below. This allows for easy accessibility of the modules for withdrawal. The new wide-angle hinge assembly in the enhanced front panel opens completely and allows easy access to all modules in the L60. 842812A1.CDR Figure 11–1: UR MODULE WITHDRAWAL AND INSERTION (ENHANCED FACEPLATE)

    C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the L60 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 667 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 L60 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 L60. 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 669: Logical Node Name Prefixes

    A built-in TCP/IP connection timeout of two minutes is employed by the L60 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 L60. 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 L60 will use the source Ether- net MAC address as the destination, with the multicast bit set.
  • Page 671 The L60 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 672 REMOTE IN 1 ITEM item to remote input 1. Remote input 1 can now be used in FlexLogic equations or other settings. The L60 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 673: Ethernet Mac Address For Gsse/goose

    GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the L60 is configured to use an automated multicast MAC scheme. If the L60 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.

    An ICD file is generated for the L60 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.

    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 >...
