    OVERVIEW The user can connect remotely to the L60 through the rear RS485 port or the rear Ethernet port with a PC running the EnerVista UR Setup software. The L60 can also be accessed locally with a laptop computer through the front panel RS232 port or the rear Ethernet port using the Quick Connect feature.
  • Page 19 • To configure the L60 for local access with a laptop through either the front RS232 port or rear Ethernet port, refer to the Using the Quick Connect Feature section. An Ethernet module must be specified at the time of ordering for Ethernet communications.
  • Page 20 SERIAL PORTS 10. Click the Read Order Code button to connect to the L60 device and upload the order code. If an communications error occurs, ensure that the EnerVista UR Setup serial communications values entered in the previous step correspond to the relay setting values.

    L60. This ensures that configuration of the EnerVista UR Setup software matches the L60 model number. b) USING QUICK CONNECT VIA THE REAR ETHERNET PORTS To use the Quick Connect feature to access the L60 from a laptop through Ethernet, first assign an IP address to the relay from the front panel keyboard.
  • Page 22 Now, assign the laptop computer an IP address compatible with the relay’s IP address. From the Windows desktop, right-click the My Network Places icon and select Properties to open the network con- nections window. Right-click the Local Area Connection icon and select Properties. 1-10 L60 Line Phase Comparison Relay GE Multilin...
  • Page 23 Select the Internet Protocol (TCP/IP) item from the list provided and click the Properties button. Click on the “Use the following IP address” box. Enter an IP address with the first three numbers the same as the IP address of the L60 relay and the last number dif- ferent (in this example, 1.1.1.2).
  • Page 24 Minimum = 0ms, Maximum = 0ms, Average = 0 ms Pinging 1.1.1.1 with 32 bytes of data: Verify the physical connection between the L60 and the laptop computer, and double-check the programmed IP address in setting, then repeat step 2 in the above procedure.
  • Page 25 If this computer is used to connect to the Internet, re-enable any proxy server settings after the laptop has been discon- nected from the L60 relay. Verify that the latest version of the EnerVista UR Setup software is installed (available from the GE enerVista CD or online from http://www.GEmultilin.com). See the Software Installation section for installation details.

    Figure 1–7: RELAY COMMUNICATIONS OPTIONS To communicate through the L60 rear RS485 port from a PC RS232 port, the GE Multilin RS232/RS485 converter box is required. This device (catalog number F485) connects to the computer using a “straight-through” serial cable. A shielded twisted-pair (20, 22, or 24 AWG) connects the F485 converter to the L60 rear communications port.

  • Page 30: Battery Tab

    1.5.5 BATTERY TAB The battery tab is installed in the power supply module before the L60 shipped from the factory. The battery tab prolongs battery life in the event the relay is powered down for long periods of time before installation. The battery is responsible for backing up event records, oscillography, data logger, and real-time clock information when the relay is powered off.
  • Page 31: Commissioning

    The L60 requires a minimum amount of maintenance when it is commissioned into service. Since the L60 is a microproces- sor-based relay, its characteristics do not change over time. As such, no further functional tests are required. Furthermore, the L60 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the Relay Self-Test section in Chapter 7 for details).

    Another option provides two 10Base-F fiber optic ports for redundancy. The Ethernet port supports IEC 61850, Modbus TCP, and TFTP protocols, and allows access to the relay via any standard web browser (L60 web pages). The IEC 60870- 5-104 protocol is supported on the Ethernet port. DNP 3.0 and IEC 60870-5-104 cannot be enabled at the same time.

    Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program- mable pushbuttons to clear specific records are typical applications for these commands.

    For short transmission lines the charging current is a small factor and can therefore be treated as an unknown error. In this application the L60 can be deployed without voltage sensors and the line charging current is included as a constant term in the total variance, increas- ing the differential restraint current.

    8 THEORY OF OPERATION 8.2.2 PHASE SELECTION The L60 uses phase relations between current symmetrical components for phase selection. First, the algorithm validates if there is enough zero, positive, and negative-sequence currents for reliable analysis. The comparison is adaptive; that is, the magnitudes of the three symmetrical components used mutually as restraints confirm if a given component is large enough to be used for phase selection.

    9 APPLICATION OF SETTINGS 9.1PHASE COMPARISON ELEMENT 87PC 9.1.1 DESCRIPTION The L60 Phase Comparison relay is designed to provide high-speed protection of transmission lines against all phase and ground faults when operated in the “mixed-excitation” mode. 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 416 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™ operands 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.

    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 Zone 2 and the fuse failure element. Therefore, for maximum security, it is recom- mended to both set the current supervision above the maximum load current and use the Fuse Failure function.
  • Page 425: Description

    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.

The TP4/CLNP profile requires the L60 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the L60 to have an IP address to establish communications. These addresses are located in the menu.

    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.

The L60 relay will contain a subset of protec- tion elements from this list. • PDIF: transformer instantaneous differential, transformer percent differential •...
  • Page 516 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 518: C.3.6 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.

    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 522: C.5.1 Overview

    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.
  • Page 523: 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 L60 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.
  • Page 524: 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 >...
