摘    要：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．

Abstract: 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.
