统一潮流控制器 ( UPFC)控制规律的求取是 UPFC装置实现其功能的关键 ,而研究UPFC的功率特性是解决 UPFC控制问题的前提 ,为此建立了含 UPFC的电力系统稳态模型 ,通过合理地选取控制变量 ,将状态方程线性化 ,分析了 UPFC的功率控制特性和多个 UPFC功率特性间的相互影响程度。通过实际潮流计算结果与线性化后所得结果的比较 ,表明
The control rules of UPFC is the key to realize its function,but it is based on the power flow control characteristic of the power system.In this paper,a steady state model for UPFC is established first,then the total system is linearized by choosing UPFCs proper control variable.According to this,the UPFC control characteristic of power flow is analyzed,including the relation that there are more than one UPFC in a power system.By contrasting the linearized results with the results of power flow calculation,we can see clearly that the UPFCs action to the power system tends to be linearization.
