无功补偿技术和无功补偿设备分析

Discussion of the Reactive Compensation Technology and the Analysis of the Reactive Compensation Equipments

无功功率是指维持电源和电气设备的电容和电感之间进行的电磁能量交换必须的功率,在电力系统中,有效率的无功补偿对整个电力网安全、有效地运行非常重要。无功补偿装置已经由同步调相机、并联电容器发展到了静态无功补偿装置。文中对几种无功补偿技术的原理和特点进行了分析、比较,并对静止无功发生器的前景进行了展望。

The concept of the reactive power is the kind of power of electromagnetic energy exchange which is between power and electrical equipments. In the power system, iFs important to have the effective reactive compensation for the safe, economic and high quality operation. Reactive compensation devices have been developed from synchronous condensers, shunt capacitors to static compensation. This paper analyzes and compares the principle and peculiarities of several leading reactive compensation techniques and looks into the future of SVG（static var generator）.
