摘要

继电保护与安全稳定控制系统的隐性故障成为国内外大停电事故的重要诱因之一。对继电保护隐性故障的研究现状

从隐性故障分类、隐性故障概率模型、对电网影响分析方法及隐性故障监测措施4个方面作了综述。安全稳定控制系统的隐性故障研究才刚起步

根据安全稳定控制系统的特点

提出了其在测量、策略、定值、通信和表决模式5个环节中可能存在的隐性故障。简要分析了继电保护、安全稳定控制系统和电厂涉网参数的配合隐患导致的隐性故障可能对电网造成的影响。最后指出未来隐性故障研究的方向包括建模、评估方法、研究成果应用、继电保护和安全稳定控制系统配合隐患问题以及二次设备运行管理5个方面。

Abstract

In recent years

hidden failures of protection systems and security and stability control systems have become one of the main causes of power system blackouts all over the world. In the paper

the research on hidden failures of protection system is summarized in four aspects

including classification of hidden failure types

the probability model for hidden failures

analyzing methods of hidden failures’ impact on a power grid

and monitoring measures for hidden failures. The research on hidden failures of security and stability control systems has just started. Based on the characteristics of security and stability control systems

hidden failures that may exist in five links are pointed out

i.e. measuring

control strategy

setting

communication and voting pattern. The hidden failures resulting from the coordination problems among protection system

security and control system and power plant’s parameters related to the grid are also briefly discussed. Toward the end

the paper gives an outlook on the directions of future research for hidden failures: model building

assessment methods

application of research results

coordination between protection system and security and stability control system

and operation management of secondary equipment.
