For current elements, the ‘base quantity’ is the nominal secondary or primary current of the CT. For voltage elements the ‘base quantity’ is the nominal primary voltage of the protected system which corresponds (based on VT ratio and connection) to secondary VT voltage applied to the relay.

(both protection B90 FUNCTION and logic), download the same file to all the B90 IEDs, and modify the settings accordingly to finalize the application. Com- munications and settings are typically modified when downloading the common B90 setting file.
Page 124 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 B90, the remote password must be used. If the connection is to the RS232 port of the faceplate, the local password must be used.
Page 125 The new password is accepted and a value is assigned to the item. ENCRYPTED PASSWORD If a command or setting password is lost (or forgotten), consult the factory with the corresponding Encrypted Password value. GE Multilin B90 Low Impedance Bus Differential System...
Page 126 INVALID ATTEMPS BEFORE LOCKOUT The B90 provides a means to raise an alarm upon failed password entry. Should password verification fail while accessing a password-protected level of the relay (either settings or commands), the FlexLogic™ operand is UNAUTHORIZED ACCESS asserted.

Page 128: 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 B90 applies a cut- off value to the magnitudes and angles of the measured currents.
Page 129: Clear Relay Records
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 B90 responds to rising edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.
Page 130: Communications
0 ms The B90 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 131 MODBUS SLAVE ADDRESS grammed. For the RS485 ports each B90 must have a unique address from 1 to 254. Address 0 is the broadcast address which all Modbus slave devices listen to. Addresses do not have to be sequential, but no two devices can have the same address or conflicts resulting in errors will occur.

Page 133 TIMEOUT: 120 s The B90 supports the Distributed Network Protocol (DNP) version 3.0. The B90 can be used as a DNP slave device con- nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the B90 maintains two sets of DNP data change buffers and connection information, two DNP masters can actively communicate with the B90 at one time.
Page 134 DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000 V on the B90 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 135 (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 B90 can be configured to sup- port paired control points, with each paired control point operating two virtual inputs.
Page 136 The B90 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 B90 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 137 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 B90 releases previous to 5.0x, this name string was repre- sented by the setting.
Page 138 DESTINATION MAC address; the least significant bit of the first byte must be set. In B90 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 B90) and setting the multicast bit.
Page 139 The B90 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.

To set up a B90 to receive a configurable GOOSE dataset that contains two IEC 61850 single point status indications, the following dataset items can be selected (for example, for configurable GOOSE dataset 1): “GGIO3.ST.Ind1.stVal” and “GGIO3.ST.Ind2.stVal”.

The most dependable protection of the initiating contact is provided by directly measuring current in the tripping circuit, and using this parameter to control resetting of the initiating relay.

9.2.1 DYNAMIC BUS REPLICA MECHANISM The bus differential zones of the B90 allow for protecting bus sections that include circuits that are switchable between dif- ferent sections. Proper relay operation is achieved by associating a status signal with each input current. This mechanism is referred to as a dynamic bus replica.
Page 291: Biased Differential Characteristic
Figure 9–2: BIASED OPERATING CHARACTERISTIC The higher slope used by the B90 acts as an actual percentage bias regardless of the value of the restraining signal.

Page 293: Enhanced Security
9.3 DIFFERENTIAL PRINCIPLE 9.3.3 ENHANCED SECURITY In order to enhance the performance of the B90, the differential characteristic is divided into two regions having diverse operating modes as shown in following diagram. The first region applies to comparatively low differential currents and has been introduced to deal with CT saturation on low- current external faults.
Page 294: Current Directional Protection
9.4.1 CURRENT DIRECTIONAL PROTECTION For better security, the B90 uses the current directional protection principle to dynamically supervise the main current differ- ential function. The directional principle is in effect permanently for low differential currents (Region 1 in Figure 9–3: Two Regions of Differential Characteristic) and is switched on dynamically for large differential currents (Region 2 in the same figure) by the saturation detector (see Section 9.5: Saturation Detector) upon detecting CT saturation.
Page 295: Ct Saturation Detection
9.5.1 CT SATURATION DETECTION The saturation detector of the B90 takes advantage of the fact that any CT operates correctly for a short period of time even under very large primary currents that would subsequently cause a very deep saturation. As a result of that, in the case of an external fault, the differential current stays very low during the initial period of linear operation of the CTs while the restraining signal develops rapidly.
Page 296: Output Logic
Figure 8-10 presents the bus currents and the most important logic signals for the case of an external fault. Despite very fast and severe CT saturation, the B90 remains stable. Figure 8-11 presents the same signals but for the case of an internal fault. The B90 trips in 10 ms (fast form-C output con- tact).

Assuming 0.003 Ω/m lead resistance and approximating the B90 input resistance for the 5A input CTs as 0.2 VA / (5 A) 0.008 Ω, the limits of the linear operation of the CTs have been calculated and presented in the Limits of Linear Operations of the CTs table.
Page 303: Low Breakpoint
A combination of very high residual magnetism and a DC component with a long time constant may saturate a given CT even with the AC current below the suggested value of the lower breakpoint. The relay copes with this threat by using a 2- out-of-2 operating mode for low differential currents. GE Multilin B90 Low Impedance Bus Differential System 10-5...

Page 377: C.1.1 Introduction
The B90 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks. The TP4/CLNP profile requires the B90 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the B90 to have an IP address to establish communications. These addresses are located in the ...
Page 378: C.2.1 Overview
C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the B90 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 379: C.2.6 Mmxn: Analog Measured Values
C.2.6 MMXN: ANALOG MEASURED VALUES A limited number of measured analog values are available through the MMXN logical nodes. Each MMXN logical node provides data from a B90 current and voltage terminal. There is one MMXN available for each configurable terminal (programmed in the ...

Page 381: C.3.1 Buffered And 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 B90. 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 382: C.3.6 Logical Node Name Prefixes
A built-in TCP/IP connection timeout of two minutes is employed by the B90 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 B90. This frees up the con- nection to be used by other clients.
Page 383: 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 B90 will use the source Ether- net MAC address as the destination, with the multicast bit set.
Page 384 The B90 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 385: C.4.5 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 B90 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 386: C.4.6 Gsse Id And Goose Id Settings
GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the B90 is configured to use an automated multicast MAC scheme. If the B90 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 387: C.5.1 Overview
An ICD file is generated for the B90 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 388: 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 B90 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.
Page 389: 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 390 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.

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 B90 settings file is typically much quicker than create an ICD file directly from the relay.
Page 394 Like ICD files, the Header node identifies the SCD file and its version, and specifies options for the mapping of names to signals.

Figure 0–9: SCD FILE STRUCTURE, IED NODE C.5.6 IMPORTING AN SCD FILE WITH ENERVISTA UR SETUP The following procedure describes how to update the B90 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 397 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.
