摘要(Abstract):

针对某次宾金直流单极闭锁事故,详细介绍了事故前后浙江电网运行状态以及宾金直流单极闭锁后金华换流站重要事件顺序。在BPA程序中搭建了与实际系统一致的发电机、励磁以及特高压直流模型,发电机调速器采用典型参数。参照事故后电网实际动作逻辑,利用BPA开展了事故再现分析,并将仿真结果与PMU实测曲线进行对比,结果表明仿真曲线与PMU曲线较为吻合,验证了仿真方法与仿真模型的有效性。
The operation status of Zhejiang power grid before and after unipolar block that occurred on July 13 and important event sequence of Jinhua converter station after the accident are introduced. Models of generators,excitation systems and UHVDC identical to real the real systems are established in BPA and the parameters of speed regulators are classic values. According to post-accident action logic of the power grid,accident reconstruction and analysis are presented by BPA; in addition,the simulation results and curves measured by PMU are compared,which shows that the simulation curves tally with curves measured by PMU and confirms the effectiveness of the simulation method and model.
