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 L30 Line Current Differential System GE Multilin...
Page 15: Software Architecture
Employing OOD/OOP in the software architecture of the L30 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.

Page 50: 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 51: 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 52: Protection And Control Functions
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.

Page 141: 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 142 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 143 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.

To reset the unit after a lost password: Email GE customer service at multilin.tech@ge.com with the serial number and using a recognizable corporate email account. Customer service provides a code to reset the relay to the factory defaults.
Page 145 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 161 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 162: Clear Relay Records
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 163: Communications
ETHERNET NETWORK TOPOLOGY The L30 has three Ethernet ports. Each Ethernet port must belong to a different network or subnetwork. Configure the IP address and subnet to ensure that each port meets this requirement. Two subnets are different when the bitwise AND oper- ation performed between their respective IP address and mask produces a different result.

Page 173 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 174 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 175 (for circuit breakers) or raise/lower (for tap changers) using a single control point. That is, the DNP 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.

Page 177 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. 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 178 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 179 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.

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.

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.

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 447: 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 448: 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 449: Relay Synchronization
8.1 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 450: Description
8.2OPERATING CONDITION CHARACTERISTICS 8.2.1 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.

The local and remote currents are 180° apart, which represents an external fault.

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.

9.1.2 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.

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 595: C.1.1 Introduction
LAN environment. Actual MMS protocol services are mapped to IEC 61850 abstract ser- vices in IEC 61850-8-1. The L30 relay supports IEC 61850 server services over TCP/IP. The TCP/IP profile requires the L30 to have an IP address to establish communications. These addresses are located in the ...
Page 596: C.1.3 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.
Page 597: 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 598: 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 599 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 600: 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 601: 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.
Page 602: C.4.1 Overview
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 603 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 604 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 605: 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 606: C.5.1 Overview
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 607: 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 608: 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 >...
Page 609 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.

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 616 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.
