RED615线路差动保护继电器

继电保护装置RED670二次回路增加控制回路断线功能作者：张法胜来源：《电气传动自动化》2019年第05期摘要：通过研究ABB公司RED670线路差动保护装置，发现该装置不具备控制回路断线监视等功能，该功能实现必须外加元件。

关键词：线变组;保护装置;控制回路断线文章编号：1005-7277（2019）05-0213-02Abstract：Through the research on ABB RED670 line differential protection device， it is found that the device does not have control loop disconnection monitoring and other functions.Key words：Wire is set; Protective device; Control loop disconnected0 引言华北石化公司共有3座110kV变电站，110kV总变电站110kV侧为双母线分段接线，另外2座110kV变电站电源引自总变电站，采用线路变压器组接线。

总变电站110kV侧一次设备为ABB公司GIS设备，线路变压器组保护装置采用ABB公司RED670线路差动保护，保护構成见图1。

RED670集保护、测控于一体，具有保护功能配置灵活、硬件可扩展等特点，由电源模块、模拟量输入模块、开关量输入模块、开关量输出模块、通信模块、时间同步模块等组成。

但通过研究发现，该装置没有国内110kV线路保护装置自带控制回路断线监视功能的插件。

若直接应用，不能构成完整的保护测控装置，不满足国内有关设计规范。

1 控制回路断线问题在电力系统中，断路器是保证正常供电，切除故障的重要设备，为保证断路器可靠动作，通常设置断路器控制回路断线监视回路，监视断路器合、跳闸线圈及断路器控制回路的完好性，并在断路器控制回路断线时报警。

地铁供电故障处理措施探讨摘要：地铁用电量是非常巨大的，作为地铁正常运作的重要支撑部分，其故障发生带来一定的负面影响。

本文主要对A\B地铁线路的交流电故障进行分析，提出解决措施，避免往后此类故障的发生。

关键词：城市轨道；供电系统；交流送电；故障；措施前言地铁采用集中供电模式，环网电缆连接变电所逐所送电，不能越所带电，因此，中间任何一个环节出现故障均会影响到送电进程。

一、地铁各变电所送电流程二、地铁供电故障案例与措施（一）主变电站至正线变电所环网电缆相序（A相、B相电缆接反）错误故障：在B线A站主变电站向B站变电所电缆送电后核相，发现A相、B相电缆接反，当时送电组有人提议继续送电，可将此处的相序按错误的相序记住倒着核，但这将会引起相序混乱，尤其影响电源备投最终导致设备故障或威胁人身安全。

解决方案：暂停送电，做好防护措施，让施工人员倒完相序后再行送电。

此类问题应发现一处，纠正一处。

避免方法：试验人员完成电缆试验，并用油漆笔在电缆头1m外标示相序，安装人员严格按标示对应安装。

（二）电缆屏蔽层未接地故障A线从A站变电所2#馈线柜向B站变电所2#进线电缆送电时，A站35kV开关柜的电缆室听到有嗞嗞的异响，按程序立即分闸，经排查为电缆屏蔽层未接地。

根据《电力工程电缆设计规范》（GB50127-2007），第4.1.19条电力电缆金属护层必须直接接地。

4.1.11条规定交流系统单芯电力电缆金属层接地方式的选择，应符合下列规定：1线路不长，且能满足本规范第4.1.10条要求时，应采取在线路一端或中央部位单点直接接地。

2线路较长，单点直接接地方式无法满足本规范第4.1.10条要求时，水下电缆、35kV及以下电缆或输送容量较小的35kV及以上电缆，可采取在线路两端直接接地。

此次事故是因施工人员疏忽未按设计要求造成该端电缆屏蔽层未接地而引起的。

解决方案：做好停电作业防护措施，对电缆放电后，将该电缆屏蔽层做接地。

避免方法：除施工按设计要求规范作业外，还应加强复查、验收。

Line differential protection and control RED615Compact and versatile solution for utility and industrial power distribution systemsRelion ®615 seriesIdeal selectivity for two-end line differential protectionRED615 is a phase-segregated, two-end line differential protection and control relay for protection, control, measurement and supervision in utility and industrial power distribution systems, including radial, looped and meshed distribution networks, with or without distributed power generation. RED615 is also ideal for line differential applications with an in-zone transformer. RED615 relays communicate between substations either over a fiber-optic link or a galvanic pilot wire connection.ApplicationRED615 has been designed to be the main protectionfor overhead line and cable feeders, in either isolated neutral, resistance-earthed, compensated or effectively earthed distribution networks, depending on the standard configuration.RED615 is available in five standard configurations, one of which is a plain line differential protection with overcurrent backup protection two with added earth-fault protection functionality in particular, and another two further extended with directional overcurrent as well as phase-voltage and frequency-based protection. Switch on to fault is now introduced in all standard configurations and voltage unbalance in the two extended ones. They both also include a fault locator which locates short circuits in radial distribution networks and earth faults in effectively and low-resistance earthed ones. If the fault current is as high as or higher than the load current, earth faults in isolated neutral distribution networks will also be located. In addition, one of the two extended standard configurations includes support for three combi-sensor inputs for phase currents (Rogowski coil)and voltages (voltage divider), whereas the other supports conventional current and voltage instrument transformers as the rest of the standard configurations.Two RED615 relays interconnected over a communication link form an entirely selective unit protection scheme. Protection of ring-type and meshed distribution networks generally requires unit protection solutions, also applied in radial networks containing distributed power generation.The standard configurations can be tailored to meet application-specific requirements using the IEC 61850-compliant Protection and Control IED Manager PCM600. Human-machine interfaceAs a member of the Relion® product family, RED615 shares the same human-machine interface (HMI) look and feel as the other Relion protection and control relays and IEDs. The same look and feel includes the location of a push button with a certain function and the menu structure.RED615 is equipped with a large graphical display whichcan show customizable single-line diagrams (SLD) with position indication for the circuit breaker, disconnectors and the earthing switch. Also measured values provided by the chosen standard configuration can be displayed. The SLDs are customized using PCM600 and can have multiple pages for easy access to selected information. The SLDs can be accessed not only locally but also via the web browser-based HMI that has now been enriched with a number of usability enhancing features.Standardized communicationRED615 fully supports the IEC 61850 standard for communication and interoperability of substation automation devices, including fast GOOSE messaging and now alsoIEC 61850-9-2 LE and Edition 2, offering substantial benefits in terms of extended interoperability. The line differential relay further supports the DNP3, IEC 60870-5-103 and Modbus®protocols, now introducing also the parallel redundancy protocol (PRP) and the high-availability seamless redundancy (HSR) protocol. With the protocol adapter SPA-ZC 302, Profibus DVP1 can also be used. RED615 is able to use two communication protocols simultaneously.For redundant Ethernet communication, RED615 offers two optical Ethernet network interfaces. The redundant Ethernet solution can be built on the Ethernet-based IEC 61850, Modbus® and DNP3 protocols.The implementation of the IEC 61850 standard in RED615 covers both vertical and horizontal communication, including GOOSE messaging with both binary and analog signalsas well as parameter setting according to IEC 61850-8-1.In addition, IEC 61850-9-2 LE process bus with sending sampled values of both analog voltages and currents and receiving sampled values of voltages is introduced. The sampled values can also be used for synchro-check, bothin conventional instrument transformer and sensor-based applications, to ensure safe interconnection of two networks. For process bus applications, which require high-accuracy time synchronization, IEEE 1588 V2 is used, with a time stamp resolution of not more than four microseconds.IEEE 1588 V2 is supported in all variants with a redundant Ethernet communication module. In addition, RED615 supports synchronization over Ethernet using SNTP or over a separate bus using IRIG-B.Main benefits−Withdrawable plug-in unit design for swift installation and testing−Selective unit protection as phase-segregated two-end line differential protection, either with sensors or conventional2 Line-differential protection and control | RED615Protection function overview of the E configuration of RED615.instrument transformers−Ready-made standard configurations, including line differ-ential communication, for fast and easy setup with tailoring capabilities−Line differential communication between substations either over a fiber-optic link or a galvanic pilot wire connection−Ideal for line differential applications with an in-zone trans-former−IEC 61850 Edition 2 and Edition 1 support, including HSR and PRP, GOOSE messaging and IEC 61850-9-2 LE for less wiring and supervised communication−IEEE 1588 V2 for high-accuracy time synchronization and maximum benefit of substation-level Ethernet communica-tion−Large graphical display for showing customizable SLDs, accessible either locally or through a web browser-based HMI 615 seriesRED615 is a member of ABB’s Relion product family and part of its 615 protection and control series of relays, characterized by compactness and withdrawable plug-in unit design.
