【摘要】 为掌握了解TCSCAC的正常运行性能,必须对它进行稳态分析。提出了考虑电抗器漏抗后的变耦电抗装置的等效电抗公式,得出了理论电抗特性;以伊―冯500 kV输电系统为应用背景,进行单回输电的功率调节仿真分析,得出了输电系统状态参数及串补装置各组成设备的电流、电压及工作容量的变化规律,为TCSCAC的各组成设备的选择设计运行提供了依据。同时还进行了动态模拟试验,并对变耦电抗装置的实际电抗特性进行了测试,试验和测试结果表明,实际特性和理论分析特性基本一致。更确切地和TCSC从理论上进行了经济性能比较分析,其结果是TCSCAC所需主设备元件的最大工作容量要比TCSC大幅度降低。更多还原

【Abstract】 An analysis of steady-state of TCSCAC is necessary to grasp its working performance. Thus this paper proposes the equivalent reactance formula of adjustable coupling reactance devices with reactance leakage of reactors,figuring out the theoretic reactance characteristic. Based on Yimin-Fengtun 500 kV transmission system,simulations and analyses of single transmission line are conducted,and attain the state parameters of transmission system and the change law of the current,voltage and working capacity of the series compensation devices. This provides the basis for selecting,designing and running the TCSCAC device components. Besides,the research has made dynamic simulation tests and detected the practical reactance performances of adjustable coupling reactance devices. The results show that practical performance accords with that based on theoretical analysis. A more accurate theoretic analysis of its( TCSCAC) economic performance compared with TCSC is conducted. And the analysis result shows that the max capacity needed by TCSCAC’ s main device components,is decreased significantly than that of TCSC.更多还原
