摘要
提出了计算电力系统非全相振荡时最大断口电势的简便方法。考虑到电网接线的影响,综合利用发电机分群原理及二端口混合参数方程,推导出与分群结果无关的一种新的断口电势计算公式。对复杂环网非全相振荡时最大断口电势计算的算例表明,该方法有效且满足实际电网整定计算的要求。
A simple method for calculating maximum open-circuit potential was presented when power system was in the non-full phases and swings operation. Based on grouping theorem for generators and hybrid equation of two-port, the procedure to calculate open-circuit potential considering electric network structure was deduced, which is independent of the result of grouping generators. It meets the requirements of relay setting through a calculated example in complex ring net.
