摘要

并网测试是新建电厂并网发电之前必须进行的工作

对于电力系统安全稳定运行具有十分重要的意义。本文针对某水电站并网测试期间

发电机组对线路进行冲击合闸试验环节的事故案例进行了详细的分析

利用DIgSILENT/PowerFactory软件对事故工况进行了仿真复现

并提出事故的解决策略及其最佳配置方案;对并联电抗器不同安装位置及补偿度对系统的不同效果进行了理论分析

提出了相应的最佳解决策略

并验证了该策略的有效性及可行性。研究内容及结果具有一定的理论分析和工程应用指导意义。

Abstract

Grid connection test is the work that must be done before the grid connection generation of new power plant and is of great significance for safe and stable operation of power system. In this paper

the fault during pulse closing test of generator unit on the line is analyzed in detail during the grid connection test period of certain hydra power plant.The fault is simulated and reproduced by DIgSILENT/PowerFactory software

and the solution strategy and optimal allocation scheme of the fault is proposed. The theoretical analysis for different installation position of shunt reactor and different effect of compensation to the systemis made

the corresponding optimal solution is proposed and the effectiveness and feasibility of the strategy is verified. Both the study contents and result have definite instruction significance for the theoretical analysis and engineering application.
