摘　　要：电力系统的运行方式是一个连续转移过程。将单点的无功优化控制扩展到考虑运行方式转移过程,从而使电压控制的可操作性和效率更符合实际需求。构建了包括变压器档位在内的非线性约束条件下的无功最优化目标函数,提出了优化和潮流计算相互迭代算法,两个实例分析说明了考虑转移过程的无功优化控制具有更好的鲁棒性和效率。The operating mode of power system is a continuous transition process. The reactive poweroptimization control of single point is extended with considering the transition process of power system operating mode,which makes the operability and efficiency of voltage control more com-pliable with the practical requirements. The objective function of reactive power optimization is set up including the nonlinear constraint of transformer tap positions. The iterative algorithm of alterna-ting optimization computation and power flow computation is presented. The analysis of two exam-ples show that the transition-optimized reactive power control has better robusticity and efficiency.
