摘要

电力系统级联停电往往是一个复杂的现象,最终可能导致大面积停电。检测和预防级联停电对维护电力系统的可靠性和安全性至关重要。本文讨论了一种通过协调全系统和全变电站监控工具来检测级联事件的方法的实现。首先给出了实现框架。详细研究了所提出的全系统和局部变电站算法的数据要求。概述了传统的监控和数据采集系统(SCADA)与现代智能电子设备(ied)的集成,以获取和处理数据。基于实际电力系统模型的算例分析表明,该算法是可行的。这些检测工具可以作为系统操作员处理级联事件情况的决策支持。

Detection tools for disturbances and protective relay operations leading to cascading events
The power system cascading outage is quite often a complex phenomenon, which may finally result in a large area blackout. Detecting and preventing cascading blackouts is crucial to maintaining the power system reliability and security. This paper discusses implementation of a method used to detect the cascading events by coordinating the system-wide and substation-wide monitoring and control tools. The framework of the implementation is given first. The data requirements for the proposed system-wide and local substation algorithms are investigated in detail. Obtaining and handling data through integration of traditional Supervisory Control and Data Acquisition (SCADA) system and modern Intelligent Electronic Devices (IEDs) is outlined. Case studies based on a real power system model shows the proposed algorithms are feasible. These detection tools could work as decision-making support for system operators to deal with cascading event situations.
