| 摘 要： | 随着风电迅速发展,风电场规模和单机容量越来越大,风电对接入的电网的影响不容忽视。而风资源丰富的地区大多电网不够强壮,加之风电自身故有的无功特性(吸收或者不发无功),风电接入对电网电压稳定性的影响显得尤为突出。对基于普通异步发电机的恒速风电机组构成的风电场与基于双馈感应发电机的变速恒频风电机组构成的风电场接入电网后的暂态电压稳定性,通过电力系统仿真软件DigSILENT并结合实际电网进行分析,给出风电场不同出力情况下的故障极限切除时间。关于静止无功补偿装置(SVC)和静止同步补偿器(STATCOM)对异步机风电场暂态电压稳定性的改善也进行了研究。

| Abstract: | With the increasing share of wind power in a power system,the impact of its integration cannot be ignored.A regional grid which has a lot of wind resources is mostly not strong.Combined with the reactive power performences of wind farms,the voltage stability of the grid with wind farm integration is particularly important.The transient voltage stability of the grid was analyzed for the cases of integration with DFIG(doubly fed induction generator) based wind farms and IG(induction generator) based wind farm... |
