As such, no further functional tests are required. The L30 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 L30 maintenance be scheduled with other system maintenance.

(DTT) signal to all of the other L30 relays on the protected line. If a slave L30 relay issues a trip from one of its backup functions, it can send a transfer trip signal to its master and other slave relays if such option is designated.
Page 43: Channel Monitor
2.2.2 CHANNEL MONITOR The L30 has logic to detect that the communications channel is deteriorating or has failed completely. This can provide an alarm indication and disable the current differential protection. Note that a failure of the communications from the master to a slave does not prevent the master from performing the current differential algorithm;...
Page 44: Loopback Test
The L30 includes provision for sending and receiving a single-pole direct transfer trip (DTT) signal from current differential protection between the L30 relays at the line terminals using the pilot communications channel. The user may also initiate an additional eight pilot signals with an L30 communications channel to create trip, block, or signaling logic. A FlexLogic operand, an external contact closure, or a signal over the LAN communication channels can be assigned for that logic.
Page 45: Functionality
Current differential protection: The current differential algorithms used in the L30 Line Current Differential System are based on the Fourier transform phaselet approach and an adaptive statistical restraint. The L30 uses per-phase differential at 64 kbps with two phaselets per cycle. A detailed description of the current differential algorithms is found in chapter 8.

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 L30 responds to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.
Page 147 0 ms The L30 is equipped with up to 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 parity.

Page 152 TIMEOUT: 120 s The L30 supports the Distributed Network Protocol (DNP) version 3.0. The L30 can be used as a DNP slave device con- nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the L30 maintains two sets of DNP data change buffers and connection information, two DNP masters can actively communicate with the L30 at one time.
Page 153 DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000 V on the L30 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 154 5.2 PRODUCT SETUP 5 SETTINGS master can operate a single point for both trip and close, or raise and lower, operations. The L30 can be configured to sup- port paired control points, with each paired control point operating two virtual inputs. The DNP NUMBER OF PAIRED CONTROL setting allows configuration of from 0 to 32 binary output paired controls.
Page 155 The L30 supports the Manufacturing Message Specification (MMS) protocol as specified by IEC 61850. MMS is supported over two protocol stacks: TCP/IP over ethernet and TP4/CLNP (OSI) over ethernet. The L30 operates as an IEC 61850 server. The Remote inputs and outputs section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.
Page 156 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 L30 releases previous to 5.0x, this name string was repre- sented by the setting.
Page 157 DESTINATION MAC address; the least significant bit of the first byte must be set. In L30 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 L30) and setting the multicast bit.
Page 158 The L30 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 164 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 L30 virtual inputs.

The second major technical consideration is the restraint characteristic, which is the decision boundary between situations that are declared to be a fault and those that are not. The L30 uses an innovative adaptive decision process based on an on-line computation of the sources of measurement error. In this adaptive approach, the restraint region is an ellipse with variable major axis, minor axis, and orientation.

Page 422: Ground Differential Element
The line ground differential function allows sensitive ground protection for single-line to-ground faults, allowing the phase differential element to be set higher (above load) to provide protection for multi-phase faults. The L30 ground differential function calculates ground differential current from all terminal phase currents. The maximum phase current is used for the restraint.

In all cases, an estimate of phase error is computed and used to automatically adapt the restraint region to compensate. Frequency tracking is provided that will accommodate any fre- quency shift normally encountered in power systems. GE Multilin L30 Line Current Differential System...

1_A k   1_ADA_A 1_MAG_A Another source of the measurement errors is clock synchronization error, resulting in a clock uncertainty term. The L30 algorithm accounts for two terms of synchronization error corresponding to: • Raw clock deviation computed from time stamps. There are several effects that cause it to not track exactly. First, the ping-pong algorithm inherently produces slightly different estimates of clock deviation at each terminal.
Page 431: Ct Saturation Detection
For short transmission lines the charging current is a small factor and can therefore be treated as an unknown error. In this application the L30 can be deployed with- out voltage sensors and the line charging current is included as a constant term in the total variance, increasing the differ- ential restraint current.
Page 432: Differential Element Characteristics
The L30 incorporates an adaptive differential algorithm based on the traditional percent differential principle. In the tradi- tional percent differential scheme, the operating parameter is based on the phasor sum of currents in the zone and the restraint parameter is based on the scalar (or average scalar) sum of the currents in the protected zone - when the operat- ing parameter divided by the restraint parameter is above the slope setting, the relay will operate.
Page 433: Relay Synchronization
9.1 OVERVIEW The major difference between the L30 differential scheme and a percent differential scheme is the use of an estimate of errors in the input currents to increase the restraint parameter during faults, permitting the use of more sensitive settings than those used in the traditional scheme.

The operating characteristics of the L30 are fundamentally dependant on the relative ratios of the local and remote current phasor magnitudes and the angles of as shown in the Restraint Characteristics figure.

If GPS is enabled at all terminals and the GPS signal is present, the L30 compensates for the channel asymmetry. On the loss of the GPS signal, the L30 stores the last measured value of the channel asymmetry per channel and compensates for the asymmetry until the GPS clock is available.

Create FlexLogic™ similar to that shown below to switch the 87L element to Settings Group 2 (with most sensitive set- tings) if the L30 has a valid GPS time reference. If a GPS or 87L communications failure occurs, the L30 will switch back to Settings Group 1 with less sensitive settings.

Page 571: C.1.1 Introduction
The L30 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks. The TP4/CLNP profile requires the L30 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the L30 to have an IP address to establish communications. These addresses are located in the ...
Page 572: C.2.1 Overview
C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the L30 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 573: 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 L30 current and voltage source. There is one MMXU available for each con- figurable source (programmed in the ...
Page 574 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 L30 protection elements, these flags take their values from the pickup and operate FlexLogic operands for the corresponding element.
Page 575: C.3.1 Buffered/Unbuffered Reporting
C.3.4 LOGICAL DEVICE NAME The logical device name is used to identify the IEC 61850 logical device that exists within the L30. 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 576: C.3.6 Logical Node Name Prefixes
A built-in TCP/IP connection timeout of two minutes is employed by the L30 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 L30. 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 L30 will use the source Ether- net MAC address as the destination, with the multicast bit set.
Page 578 The L30 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 579 REMOTE IN 1 ITEM item to remote input 1. Remote input 1 can now be used in FlexLogic equations or other settings. The L30 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 580: C.4.5 Ethernet Mac Address For Gsse/Goose
GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the L30 is configured to use an automated multicast MAC scheme. If the L30 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 581: C.5.1 Overview
The L30 can be configured for IEC 61850 via the EnerVista UR Setup software as follows. An ICD file is generated for the L30 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 582: 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 L30 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.
Page 583: C.5.3 About Icd Files
(which also includes SSD, CID and SCD files). The ICD file describes the capabilities of an IED and consists of four major sections: • Header • Communication • IEDs • DataTypeTemplates GE Multilin L30 Line Current Differential System C-13...
Page 584 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 L30 Line Current Differential 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 L30 settings file is typically much quicker than create an ICD file directly from the relay.
Page 588 Like ICD files, the Header node identifies the SCD file and its version, and specifies options for the mapping of names to signals. The Substation node describes the substation parameters: Substation PowerSystemResource EquipmentContainer Power Transformer GeneralEquipment EquipmentContainer VoltageLevel Voltage PowerSystemResource Function SubFunction GeneralEquipment 842792A1.CDR Figure 0–7: SCD FILE STRUCTURE, SUBSTATION NODE C-18 L30 Line Current Differential System GE Multilin...
