摘要
鉴于交流侧三相对地短路故障后同步发电机失步的异常现象,通过分析静止同步串联补偿器(SSSC)及VSC-HVDC换流器的原理及控制方式,在国内首次提出将SSSC虚拟内置入VSC-HVDC换流站的控制策略。在建立MATLAB仿真模型的基础上,分析比较了有无SSSC对同步发电机转子转速的影响。仿真结果表明,该控制策略具有良好的控制性能。
Refer to the abnormal condition of the generator＇ sun-synchronous working after a three-phase ground fault applied in the ae-side, through analyzing the principle and control method of Static Synchronous Series Compensator （SSSC） and VSC-HVDC, a novel strategy was proposed to solve the problem in VSC-HVDC for the first time in this field On the basis of establishing Matlab simulation model, comparison before and after merging SSSC in VSC-HVDC was made. Simulation results show the validity and the effectiveness of the proposed control strategy.
