摘要
在分析交流电路临界电压崩溃特性的基础上,确定了交流电路支路临界电压崩溃的边界,提出了基于交流电路运行特性计算电压稳定裕度指标的方法。算例表明所提算法有效规避了在接近崩溃点附近潮流收敛困难的问题。
Based on analysis of the critical collapse point characteristics of the ahernating current circuit, this paper determines the boundary of the critical voltage collapse for the ahernating current circuit branch, and proposes a calculating method of voltage stability margin index based on operating characteristics of alternating current circuit. The calculation example shows that this method effectively avoids the power flow convergence when close to the critical voltage collapse point.
