摘要:电力系统的无功优化和无功补偿是提高系统运行电压,减小网损,提高系统稳定水平的有效手段。本文对当前常用的无功优化和无功补偿进行了总结,对目前无功补偿和优化存在的问题进行了一定的探讨和研究。电压是电能质量的重要指标之一,电压质量对电网稳定及电力设备安全运行、线路损失、工农业安全生产、产品质量、用电单耗和人民生活用电都有直接影响。无功电力是影响电压质量的一个重要因素,电压质量与无功是密不可分的,电压问题本质上就是一个无功问题。解决好无功补偿问题,具有十分重要的意义。

Abstract:Reactive optimization and pensation of power system is a valid way to increse the system’s operating voltage and maintenance level .It’s also the way to   reduce the loss . This essay summarize what Reactive optimization and pensation are in our daily life. It also discusses and studies some problems existing in reactive optimization and pensation. Voltage is one of the important targets of Quality of power supply,  whose quality will affect stabilization of power grids and  electric equipment functioning well directly. Lin loss and safety in production in industry and agriculture ,the production’s quality , electrical energy depth loss ,and electrical energy used mon people every day will be infulenced directly by it too. voltage qualit is an important factor to affect voltage quality .so voltage qualit and voltage qualit are closely related to each other. The problems about voltage is the problem of reactive energy in in all,to solve the problem of pensation well is very meaningful and necessary.
Keywords: Reactive Optimization    pensation   loss of voltage qulity    Power Factor
