摘要
文章对风电系统保护进行了论述,并就风电对电网继电保护产生的影响进行了分析,使用Matlab中动态仿真工具Simulink,对包含风电场的单机无穷大电力系统当联络线发生故障时进行动态仿真,通过双馈发电机在不同故障类型下的故障电压、电流曲线,得出风电场应采用适应性保护。
The paper discussed the relay protection of wind farm, analyzed the impact of wind farm integration on power system protection. Dynamic simulation of Matlab/Simulink was used, and the power system with single machine to infinitive bus including wind power generation was simulated. The conclusion of dynamic simulation shows that an adaptive relay protection for wind farm should be used when the short circuit fault occurred on the tie-tree and through analysis of fault voltage and current curve in different type of the fault for DFIG.
