利用Matlab中的动态仿真工具Simulink,建立了与无穷大系统相连的两机风电场模型。对系统发生三相短路故障时进行了仿真,在此基础上分析了静止同步补偿器(STATCOM)的补偿特性,并将其与SVC的补偿效果进行了比较。仿真结果表明,STATCOM能更好地提高风电场的暂态稳定性,保持风电场连续运行。
The wind farm model of two constant speed wind power generation sets that connecting with the infinite bus system is built in Matlab software.Simulation is made when three-phase short circuit fault occurs in wind farm.Based of that,the compensation character of STATCOM is also analyzed by comparison with SVC.The research result shows that STATCOM can improve the transient voltage stability of wind farm more effectively than SVC and will ensure the continuous operation of wind power generation sets.
