摘要

为了掌握变耦电抗式可控串补的实际特性,进行了动态模拟试验。以东北电网伊—冯500 kV输电系统为应用背景,建立了包括串补装置在内的整个系统的动态模拟装置,设计调试了具有多功能的控制系统,进行了电抗调节、功率调节、电抗跃变调节等基本特性试验以及暂稳控制和阻尼功率振荡试验,记录了各项调节性能曲线及调节过程中串补元件的电流电压波形。串补装置的稳态性能试验结果与理论分析结果相符,暂态性能良好,暂稳控制可进行“强补”,采用合适算法同样具有阻尼功率振荡的作用。

Dynamic Simulation of Thyristor Controlled Reactance Series Compensator by Adjustable Coupling
Guizhou University,Guiyang 550003,Guizhou Province,China
Abstract:

In order to master actual characteristics of the Thyristor Controlled Reactance Series Compensation by Adjustable Coupling (TCSCAC), dynamic simulation tests are performed. Using the 500kV power transmission system form Yimin to Fengtun in Northeast Power Grid as the application background, a dynamic simulation device containing TCSCAC is built, and the adjustment and calibration of a multi- functional control system designed for this purpose are conducted. Then the basic characteristic tests such as reactance regulation, power regulation, reactance long-step regulation, transient stability control and power oscillation damping are carried out. The regulation performance curves of these tests and the current and voltage waveforms of series compensator during these tests are recorded. Test results show that the steady state performance of TCSCAC conforms to the results of theoretical analysis, the transient performance of TCSCAC is satisfied and the high compensation can be implemented during the transient stability control process as soon as the fault is cut off. Likewise, TCSCAC can be used to suppress power oscillation while suitable algorithm is adopted.

Keywords: thyristor controlled reactance series compensator by adjustable coupling;dynamic simulation;power regulation;reactance long-step regulation;transient stability control;power oscillation damping
