摘　　要：笔者提出了晶闸管变压式电容无功补偿装置投入和换级过程的控制过程,建立了单相试验装置各过程的状态变量方程,采用数字积分对试验装置投入和换级过程的暂态电流及晶闸管断态电压进行了仿真分析,分析结果和试验结果基本吻合。分析结果表明,装置暂投入和换级过程暂态性能良好,也为换级控制提供了设计依据。The authors proposed controlling processes of capacitor reactive power compensation by adjusting voltage with thyristor in operating and grade-changing situations, set up state parameter equations of various processes for single-phase test device, stimulated and analyzed the transient current of the device and the disconnected voltage on thyristor switches in operating and grade-changing processes with digital integral. The simulation resuhs are in accordance with the test ones, indicating that the device perform well in operating and grade-changing processes. This research may offer a reference for grade-changing control design.
