摘　　要：以电力系统中无功优化的非线性规划模型为基础,采用原对偶内点算法进行全局寻优.文中通过对障碍参数确定方式的研究,根据障碍参数的物理本质以及电力系统本身的特点,提出了在运用原对偶内点算法分析电力系统无功优化时,应根据不同物理意义的变量来确定相应障碍参数的方法.在此基础上,分析了障碍参数中加速因子对算法的影响,提出了加速因子的动态确定策略.在对IEEE 118节点系统进行的计算分析表明本文算法收敛性好、计算速度快.The primal - dual interior point algorithm is applied in global optimization on the basis of non - linear programming model for optimal reactive power. The process of how to get barrier parameters which are decided by their physics meaning and the eharacter of the power system is discussed in detail. This paper gives the method of how to get accelerating factor by the influence of barrier parameters to the algorithm. The results of tests in IEEE 118 nodes system have shown that the proposed method has good caleulation speed.
