基于泰勒级数等值方法的静态电压稳定分析
Analysis of Static Voltage Stability Based on Taylor Series Equivalent Method
摘要
Abstract
When the critical point of voltage stability is calculated by continuous power flow algorithm,there are prob?lems such as computation inefficiency and the convergent difficulty of power flow equation approaching the critical point of voltage stability.To optimize computation efficiency,the research mainly discusses how to determine the a more suitable step length and work out a more accurate critical point of voltage stability.Therefore,the analysis of static volt?age stability based on the Taylor series equivalent method is put forward.Thevenin equivalent method is utilized in the dynamic analysis,and the concepts of system dynamic equivalent impedance of the system are put forward. The critical condition of reaching maximum transmission power of electronic system is verified by using the dynamic analysis meth?od.The dynamic analysis method of analytic-complex-system is strictly utilized in a non analytic-complex-system so that the load point voltage phasor and the current phasor according to Taylor extension equation of voltage mode are ob?tained. As a result,the limit power and the critical voltage can be calculated. Simulative results show that the men?tioned algorithm can calculate the system limit power and the critical voltage effectively and accurately.关键词
