电能质量讲座第三讲无功补偿及其装置

无功补偿是保证电网电压稳定与经济运行的重要手段.从无功功率产生的原因、无功功率流动对电力系统造成的影响、无功补偿的原则、无功补偿容量的配置以及无功补偿装置的发展等方面对无功补偿技术进行了全面的阐述.着重介绍了国内目前采用的无功补偿的技术原则,以及采用电力电子技术的新型无功补偿装置的原理与优缺点,为实际工作中的无功补偿提供了基础.

Lecture on Electrical Energy Quality Ⅲ.Reactive Power Compensation and its Equipment

The compensation of reactive power is an important approach to ensure the stability of power system and make the power system perform more efficient. The current situation and trends of reactive power compensation from some aspects, such as the reason of the reactive power generation, the harm of the reactive power flow, the principle of reactive power compensation, the configure of the capacity of reactive power compensation and the development of equipments of reactive power compensation, were expatiated systemically.The principle of reactive power compensation applying in China, the principle and the characteristic of the novel reactive power compensation equipment using the electric and electronics technology were introduced emphatically. A reference to the application of reactive power compensation was provided.
