The Steady-State Voltage Stability Analysis And Corrective Control Research Of Power System

This thesis was working for PMU synchronous measurement based the steady-state voltage stability analysis and voltage stability corrective control research using primal-dual interior point method.First, this thesis analyzed the steady-state voltage stability of simple power system form the analysis of Q-U curve, and then used the voltage stability criterion getting from which to analyze the voltage stability of complicated power system.Second, for utilizing PMU synchronous measurement, this thesis presented PMU synchronous measurement based general practical algorithm of voltage stability analysis in power system. It can be realized easily, which make it useful in real-time monitoring and analyzing of voltage stability.Third, considering the economy of voltage stability corrective control, this thesis used the corrective control model of satisfying system and equipments' run request and having enough voltage stability margin but cost is least. For getting the purpose of voltage stability corrective control, this thesis used primal-dual interior point method to solve the problem of optimal power flow (OPF).Forth, the calculation of standard cases indicated all the analysis is effectual and some helpful conclusion was gained form the careful analysis.
