摘　　要：针对电力系统电压崩溃问题,在负荷临界电压崩溃分析基础上,讨论功率型负荷的电力系统临界电压崩溃的潮流计算方法。提出利用交流电路临界电压崩溃的特性,规避崩溃支路,设置等值功率求解电力系统临界电压崩溃的潮流,解决临界电压崩溃潮流的不收敛问题,通过IEEE5节点算例进行验证。Targeting the electric power system voltage collapse problem, based on the analysis of the critical voltage collapse, this paper discusses the power flow calculation methods of the power system critical voltage collapse on power-type load. It proposes that collapse branch can be avoided by using characteristics of the AC circuit critical voltage collapse, and the equivalent power be set up to solve the power flow of power system critical voltage collapse and address the non-convergence of the power flow in the critical voltage collapse state. The algorithm is validated through IEEE5 node numerical examples.
