【摘要】 以东北电网拟建的500kV伊敏－冯屯交流输电系统所需可控串联补偿电容装置（TCSC）为研究目标，建立了包括TCSC的整个系统的动态模拟装置。在此基础上，进行了TCSC整体动模装置的基本运行方式、潮流控制以及暂态响应的试验，所得结果与理论分析一致。此外，单回线运行时，在接近谐振点的某一补偿度上，观察到了次同步谐振（SSR）现象，并对此现象进行了分析。更多还原

【Abstract】 A physical model composed of generators. transformers and two 500 kV long transmission lines with TCSCcompensation and used for studying control effect of TCSC on the system is described. The TCSC control system isimplemented by master-slave type multi CPU parallel processing system consisting of STD+DSP. Various disturbances andoperation modes are tested on the model. Subsynchronous resonance appears during test. and it conforms with the naturalfrequencies measured by negative sequence current excitation method.更多还原
