Page 30: Commissioning
1.5.7 COMMISSIONING The L30 requires a minimum amount of maintenance when it is commissioned into service. Since the L30 is a microproces- sor-based relay, its characteristics do not change over time. As such, no further functional tests are required. Expected ser- vice life is 20 years for UR devices manufactured June 2014 or later when applied in a controlled indoors environment and electrical conditions within specification.
Page 31: Product Description
The L30 is intended to provide complete protection for transmission lines of any voltage level. Both three phase and single phase tripping schemes are available. Models of the L30 are available for application on both two and three terminal lines.

Page 149: Introduction To Ac Sources
Sources, in the context of L30 series relays, refer to the logical grouping of current and voltage signals such that one source contains all the signals required to measure the load or fault in a particular power apparatus. A given source may contain all or some of the following signals: three-phase currents, single-phase ground current, three-phase voltages and an auxiliary voltages from a single-phase VT for checking for synchronism.
Page 150 CTs through which any portion of the current for the element being protected could flow. Auxiliary CTs are required to perform ratio matching if the ratios of the primary CTs to be summed are not identical. In the L30 relay, provisions have been included for all the current signals to be brought to the device where grouping, CT ratio correction, and summation are applied internally via configuration settings.
Page 151 Upon startup, the CPU configures the settings required to characterize the current and voltage inputs, and will display them in the appropriate section in the sequence of the banks (as described above) as follows for a maximum configuration: F1, F5, L1, L5, S1, and S5. GE Multilin L30 Line Current Differential System...
Page 152 When entering a settings or command password via EnerVista or any serial interface, the user must enter the correspond- ing connection password. If the connection is to the back of the L30, the remote password must be used. If the connection is to the RS232 port of the faceplate, the local password must be used.

Page 157: Display Properties
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 L30 applies a cut- off value to the magnitudes and angles of the measured currents.

Page 159: Communications
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. 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 160 0 ms The L30 is equipped with up to three independent serial communication ports. The faceplate RS232 port is intended for local use and is fixed at 19200 baud and no parity. The rear COM1 port type is selected when ordering: either an Ethernet or RS485 port.
Page 161 This allows the EnerVista UR Setup software to be used on the port. The UR operates as a Modbus slave device only. When using Modbus protocol on the RS232 port, the L30 responds regardless of the pro- MODBUS SLAVE ADDRESS grammed.

Page 163 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 164 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 166 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 167 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 168 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 169 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.

Various self-checking diagnostics are performed in the background while the L30 is running, and diagnostic information is stored on the non-volatile memory from time to time based on the self-checking result. Although the diagnostic information is cleared before the L30 is shipped from the factory, the user may want to clear the diagnostic information for themselves under certain circumstances.

Page 421: Theory Of Operation
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 424: 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_ADA_A 1_A k ( ) 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 433: 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 434: 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 435: 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.
Page 436: Operating Condition Characteristics
9.2OPERATING CONDITION CHARACTERISTICS 9.2.1 DESCRIPTION Characteristics of differential elements can be shown in the complex plane. 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.

Current differential section of chapter 5. The following figure shows how the L30 settings affect the restraint characteristics. The local and remote currents are 180° apart, which represents an external fault. The breakpoint between the two slopes indicates the point where the restraint area is becoming wider to override uncertainties from CT saturation, fault noise, harmonics, etc.

Practically, it is difficult to meet this criteria and avoid saturation completely. The L30 provides several means to ensure security during an external fault, including dual-slope restraint characteristics, adaptive restraint, and CT saturation mechanism, allowing the relay to be secure during severe external faults, while maintaining excellent performance for internal faults.
Page 444: Ct Saturation Analysis Tool
10.1.2 CT SATURATION ANALYSIS TOOL The CT saturation analysis tool is an Excel spreadsheet provided for users to analyze the L30 reliability during CT satura- tion caused by an external fault, to investigate the effect of adjusting 87L settings, and to examine the possibility of reducing the CT requirement.
Page 445 You are encouraged to test different fault locations and different fault levels and distributions per short circuit studies. Alter- natively, the tool can help to estimate required CT parameters (ratio and knee point voltage), based on some pre-deter- mined criteria. GE Multilin L30 Line Current Differential System 10-3...

Page 448 This satisfies the equality condition indicated earlier.

Page 449: Channel Asymmetry Compensation Using Gps
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.
Page 450: Compensation Method 2
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.

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 576: File Transfer By Iec 61850
APPENDIX C C.1.3 FILE TRANSFER BY IEC 61850 The L30 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.

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 578: 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 579 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 580: 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 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 581: 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 583 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 584: Ethernet Mac Address For Gsse/Goose
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.

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 586: Iec 61850 Implementation Via Enervista Ur Setup
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 587: 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 588: 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 >...
Page 589 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. GE Multilin L30 Line Current Differential System C-15...

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 593 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 C–7: SCD FILE STRUCTURE, SUBSTATION NODE GE Multilin L30 Line Current Differential System C-19...

Figure C–9: SCD FILE STRUCTURE, IED NODE C.5.6 IMPORTING AN SCD FILE WITH ENERVISTA UR SETUP The following procedure describes how to update the L30 with the new configuration from an SCD file with the EnerVista UR Setup software. Right-click anywhere in the files panel and select the Import Contents From SCD File item.
Page 596 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.
