摘　　要： 针对目前静止同步补偿器(Static Synchronous Compensator,STATCOM)输出建模和拓扑建模等方法的不足,通过引入单极性二值逻辑开关函数,建立了基于变换器物理特性和拓扑结构的开关函数模型。该模型的参数都是装置实际的物理参数,易于确定,更具一般性。对380V两机系统进行的仿真计算证明了所提模型和方法的正确性和有效性,并验证了STATCOM对系统无功补偿和电压稳定具有重要作用。 With consideration of the shortages of output model-constructing method and topological model-constructing method for Static Synchronous Compensator（STATCOM）,a switching function mathematical model of this device based on physical characteristics and topology of the converter is constructed by introducing the concept of the single-pole two-valued logic switching function.The parameters of the model are real physical ones of STATCOM device,which makes this model easier to be certain and more general.Simulation results of 380 V double-machine system prove that not only the proposed model and method are correct and effective,but STATCOM plays an important role on voltage stability and reactive supply in power systems.
