大电网继电自动装置的隐藏故障、脆弱性和适应性问题

Hidden failure,vulnerability and adaptability of relaying automations in large interconnected power systems

市场环境多变和不确定因素增加,特别是几次大停电以及信息技术进步的影响,对继电自动装置提出了一些新的要求。介绍了当前自动化信息化主要的研发热点:开发快速同步监控装置、加强动态安全评估的预防性控制、某些变电站间隔级单元信息纳入EMS管理。为解决涉及继电自动装置的隐藏故障监视、电力系统脆弱性分析和适应性控制等问题,以及当前出现的新型系统监视保护和动态分析预测进行了分析和讨论。

The market environment change and uncertain factor increase,especially the influence of several large-area blackouts and information technology progress,bring forward some new require-ments to relaying automations. Recent researches about automation informization focus on:develop-ment of the rapid synchronous supervisor,preventive control for improving dynamic security estimation,integration of substation cell information into EMS. The hidden failure,power system vulnerability and adaptive control regarding relaying automations are thus discussed,as well as system dynamic monitoring,predicting,protection and analysis.
