摘要
统一潮流控制器 ( UPFC)的控制规律的求取是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。本文通过控制量与被控制量之间灵敏度分析的方法 ,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。通过实际潮流计算结果和线性化后所得结果的数值比较 ,表明了所选取的UPFC的控制变量对电力系统的潮流控制作用趋向于线性。
The control rules of UPFC is the key to realize its function,but it is based on the power flow control characters of the power system ,in which it is located in.In this paper, according to the sensitivity mothod, the UPFC controllability of power flow is analysised, including the situation that there are more than one UPFC in a power system. By contrasting the linearized results with power flow calculation results ,we can clearly see that the UPFC's action to the power system tends to be linearization.
