摘　　要：总结含统一潮流控制器(unified power flowcontroller,UPFC)的系统潮流计算方法,在此基础上设计一个能与传统PQ潮流算法结合的UPFC潮流计算模型,将潮流计算结果与UPFC的稳态模型相结合,分析控制目标值与系统控制量、电气量的关系。提出一种用中间控制变量代替直接控制方式的潮流控制策略,仿真结果证明该控制策略是合理、有效的。The paper summarizes a calculation method for power flow with unified power flow controller（UPFC）,on the basis of which UPFC model for power flow calculation that can be integrated with conventional PQ calculation method is designed.By combining results of power flow calculation with steady-state model of UPFC,the paper analyzes relationship among control target value,system control quantity and electric value.It presents a flow control strategy— to substitute middle control variable for direct control mode and the simulation result proves that the control strategy is reasonable and effective.
