摘要
传统的电力系统离线安全稳定分析计算量大,计算结果较为保守且与实际运行方式差别较大,而电力系统在线安全稳定分析技术直接采用当前电网实时运行状态和数据,更加符合当前电网实际情况。调研了在线安全稳定分析技术的应用现状,详细介绍在线安全稳定分析系统的基本原理及构成模块,深入分析各个模块的运行方式和主要作用,最后通过对山东电网主网架线路跳闸后的系统特性进行在线安全稳定计算和分析,并与WAMS系统实际采集结果进行比较,验证了在线安全稳定分析计算的准确性和可靠性。
The traditional offline analysis for the power system security and stability has a large amount of calculation,and the conservative calculation results are different from the actual operation mode. In contrast,the power system online security and stability analysis accords with the actual power by using the current power grid operation state and data. In this paper,the application situation of the online analysis was investigated,the component modules and basic principles of the online security and stability analysis system were introduced,the operation mode and main function of each module were analyzed,and system characteristics of Shandong Power Grid after line tripping were calculated and analyzed finally. The comparison between the calculation results and the actual acquisition results by the WAMS system verified the high accuracy and reliability of online security and stability analysis.
