  • Page 15: Product

    2.1.1 Overview The B30 Bus Differential System is part of the Universal Relay (UR) series of products. It is a microprocessor-based relay that provides protection and metering for a busbar with up to six feeders. Protection is provided by a low impedance percent differential element with features that make it immune to current transformer (CT) saturation.

    Modbus/TCP, TFTP, and PTP (according to IEEE Std. 1588-2008 or IEC 61588), and it allows access to the relay via any standard web browser (B30 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port. The Ethernet port also supports the Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option.

    The B30 supports password entry from a local or remote connection. Local access is defined as any access to settings or commands via the faceplate interface. This includes both keypad entry and the through the faceplate RS232 port. Remote access is defined as any access to settings or commands via any rear communications port.

    The UR samples its AC signals at 64 samples per cycle, that is, at 3840 Hz in 60 Hz systems, and 3200 Hz in 50 Hz systems. The sampling rate is dynamically adjusted to the actual system frequency by an accurate and fast frequency tracking system. The A/D converter has the following ranges of AC signals: B30 BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL 2-17...

    Measured analog values and binary signals can be captured in COMTRADE format with sampling rates from 8 to 64 samples per power cycle. Analog values can be captured with Data Logger, allowing much slower rates extended over long period of time. 2-18 B30 BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL...

    Some customers prefer very low currents to display as zero, while others prefer the current to display even when the value reflects noise rather than the actual signal. The B30 applies a cut-off value to the magnitudes and angles of the measured currents.

    Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user- programmable pushbuttons to clear specific records is a typical application for these commands. Since the B30 responds to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.

    PRODUCT SETUP File transfer by IEC 61850 The B30 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.

    NUMBER: 0 The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the B30 over a network. The B30 operates as a TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file obtained from the B30 contains a list and description of all available files, for example event records and oscillography.

    COMMUNICATIONS  PROTOCOL connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the B30 maintains two sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the B30 at one time.

  • Page 254

    CHAPTER 5: SETTINGS The B30 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to which the B30 can connect. A maximum of two simultaneous connections are supported at any given time.

    PTP, or SNTP, its time is overwritten by these three sources, if any of them is active. If the synchronization timeout occurs and none of IRIG-B, PTP, or SNTP is active, the B30 sets the invalid bit in the time stamp of a time-tagged message.

    FlexAnalog operands. The measurands sent are voltage, current, power, power factor, and frequency. If any other FlexAnalog is chosen, the B30 sends 0 instead of its value. Note that the power is transmitted in KW, not W. Measurands are transmitted as ASDU 3 or ASDU 9 (type identification value set to measurands I, respectively measurands II).

  • Page 259

    Commands are received as General Command (Type Identification 20). The user can configure the action to perform when an ASDU command comes. A list of available mappings is provided on the B30. This includes 64 virtual inputs (see the following table). The ON and OFF for the same ASDU command can be mapped to different virtual inputs.

    Setup for IRIG-B is illustrated in the Installation chapter. For the Other protocols, whenever a time synchronization message is received through any of the active protocols, the B30 clock updates. However, given that IEC 60870-5-103, IEC 60870-5-104, Modbus, and DNP are low-accuracy time synchronization methods, avoid their use for synchronization when better accuracy time protocols, such as IRIG-B and PTP, are active in the system.

    See the Order Codes section in chapter 2 for details. The B30 supports the Precision Time Protocol (PTP) specified in IEEE Std 1588 2008 using the Power Profile (PP) specified in IEEE Std C37.238 2011. This enables the relay to synchronize to the international time standard over an Ethernet network that implements PP.

    The B30 supports the Simple Network Time Protocol specified in RFC-2030. With SNTP, the B30 can obtain clock time over an Ethernet network. The B30 acts as an SNTP client to receive time values from an SNTP/NTP server, usually a dedicated product using a GPS receiver.

    B30 clock is closely synchronized with the SNTP/ NTP server. It takes up to two minutes for the B30 to signal an SNTP self-test error if the server is offline.

    This mechanism is referred to as a dynamic bus replica. The dynamic bus zone is programmed as a number of ‘source-status’ pairs. The Sources feature of the B30 is a convenient and flexible mechanism for associating input currents and voltages with protection and control elements.

  • Page 474: Ct Ratio Matching

    9.2.2 CT ratio matching The B30 allows for using CTs with various rated secondary currents and transformation ratios. Scaling to a common base is performed internally by the relay. The maximum allowable ratio mismatch is 32:1. For proper setting of the differential characteristic, it is imperative to understand the common base used by the relay.

    LOW BPNT 9.3.3 Enhanced security To enhance the performance of the B30, the differential characteristic is divided into two regions having diverse operating modes, as shown in following figure. The first region applies to comparatively low differential currents and has been introduced to deal with CT saturation on low-current external faults.

  • Page 477: Directional Principle

    The B30 operates in the 2-out-of-2 mode in the first region of the differential characteristic. Both differential and directional principles (Differential Principle and Directional Principle) must confirm an internal fault in order for the biased differential element to operate.

  • Page 478

    Figure 9-6: Directional principle operation during internal faults The B30 implementation calculates the maximum angle for the considered currents and compares it against a fixed threshold of 90°. The flag indicating whether the directional protection principle is satisfied is available as the FlexLogic operand BUS 1(2) DIR.

  • Page 479: Saturation Detector

    9.5.1 CT saturation detection The saturation detector of the B30 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, 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 480: Output Logic And Examples

    For high differential signals, the directional principle is included only if demanded by the saturation detector (dynamic 1- out-of-2 / 2-out-of-2 mode). Typically, the directional principle is slower, and by avoiding using it when possible, the B30 gains speed.

  • Page 481: Internal And External Fault Example

    The first of the following figures 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 B30 remains stable. The second figure presents the same signals but for the case of an internal fault. The B30 trips in 10 ms (fast form-C output contact).
