摘要
电力系统的无功补偿与无功优化是提升系统稳定水平、系统运行电压以及减小网损的重要方式,但在电力系统中,往往会遇到包含许多变频设备的供电电力系统,那么此时的系统补偿不可能只是以设备的功率因素作为基础来思考,而必须从配电系统构成以及变频特性和电网谐波等多个方面来考虑,一次最终确定好补偿的方案。接下来,分析研究了含有变频设备供电系统无功补偿问题。
Reactive compersation and reactive optimum of the power system are an important way to increase stable sys- tem level, system running voltage and decrase the network losses. In the power system, there are a lot of variable frequen- cy equipments in the power supply system, So then the system compensation can not only be as an equipment power fac- tor to be thought, they must be considered in many respects from the distrubition system form,variable frequency charac- teristic and electric network harmonic. It analyzes and studies the reactive compensation of the power supply system in- cluding the variable frequency equipment.
