| 摘 要： | 以东北电网拟建的５００ｋＶ伊敏－冯屯交流电系统所需可控串联电容装置（ＴＣＳＣ）为研究目标，建立了相应的动态模拟装置，并利用负序电流激振法测量动模发电机组的自然谐振频率，在此基础上激发现罕见的次同步谐振（ＳＳＲ）现象，文章对ＳＳＲ现象发生的机理作了详细讨论，提出了ＴＣＳＣ“激振频带”概念。最后对ＴＣＳＣ系统中次同步谐振发散后ＭＯＶ行为进行了讨论。

| Abstract: | A physical model of power system is used in the study of subsynchronous resonance(SSR) stemmed from thyristor controlled series capacitor(TCSC). The models of generating sets, transformers, transmission lines and TCSC are described. The natural frequencies of the model machine shaft-system are measured by negative sequence current excitation method. The series resonance frequency of the stator circuit is not only calculated, but also measured. Several SSR phenomena, including the influence of metallic oxide valves(MOV), are studied by this physical model and some conclusions are drawn. |
