一种具有无功补偿功能的晶闸管变流装置

A NEW THYRISTOR CONVERTER BASED ON REACTIVE POWER COMPENSATORY TECHNIQUE

针对普通晶闸管变流装置深控时功率因数低的问题，在分析了晶闸管超前相控基理及其实现条件的基础上，提出了一种采用晶闸管超前相控、提供无功补偿的方法．现场运行结果表明：该装置在输出有功功率的同时，还可根据需要提供无功补偿，提高了电网功率因数，减小了无功损耗，节约了电能，经济效益和社会效益显著．

As the power factor of a deep controlled thyristor converter is very low, a new approach based on phase lead reactive power compensation technique is proposed in this paper. Application proves that it can provide reactive power compensatory as needed, increase the power supply network's power factor, decrease the wastage of reactive power and save energy consumption. This paper also describes the theory and the realizing condition of phase lead control.
