保障电力系统可靠安全运行和电质量符合标准的要求,采取措施从而增大生产和传输电能,这是经济运行电力系统的基本原则.寻找一种技术可靠和经济可行的措施显得相当有意义.无功功率补偿是主要的提高电能生产和传输的主要措施之一.而电力电容器是现在最普遍的补偿设备,其经济性很好且效果快.本文对电力电容做了简单的介绍,叙述了为提高电力系统的经济运行,在选择电力电容的容量的选择.%Ensuring the reliable and safe operation of power system and requirements of power quality conforming to the standards and taking measures to increase the production and transmission of electrical energy is the basic principle of power system of economic operation. It is quite meaningful for exploring the measure with technical reliability and economically feasible And reactive power compensation is one of the main measures to improve power production and transmission. Power capacitor is the most popular compensation device at present, and has good economy and fast effect. In this paper, power capacitor is introduced, and the selection of capacity of power capacitor to improve the economic operation of power system is described.
