摘要: 对晶闸管控制变压器(TCT)式可控并联电抗器结构特点进行分析,并总结其运行特点。根据晶闸管控制变压器式可控并联电抗器在90°180°范围内平滑调节容量的特性,重点分析电压取能和电流取能对其运行特性的影响,并提出晶闸管控制变压器式可控并联电抗器使用电压和电流混合取能的方法。通过建立真实动态模型,证明了该方法的可靠性和可行性,为晶闸管控制变压器式可控并联电抗器的设计提供了依据。Abstract: The structure of thyristor controlled transformer（TCT）type controllable shunt reactor is analyzed and its operating characteristics are summarized.According to the characteristic of the TCT type controllable shunt reactor that can adjust the capacity smoothly from 90°to 180°,the effect of voltage energy-gaining and current energy-gaining on its operating characteristics is emphasized,and the hybrid voltage-current energy-gaining method is proposed for application in the TCT type controllable shunt reactors.The reliability and feasibility of the hybrid voltage-current energy-gaining method is demonstrated through the establishment of a real dynamic simulation model to provide a design foundation for the TCT type controllable shunt reactors.
