摘要(Abstract)：

风火打捆能源基地的投入运行,在带来巨大经济效益的同时也引起电网安全稳定性发生变化。某些严重故障后,仅切除常规火电机组难以保证系统稳定运行或代价过大。首先分析了风电机组和火电机组暂态特性的差异性以及各自对系统暂态稳定的影响。然后指出了严重故障后导致系统失稳的2个主要原因:一是故障过程中产生了加速能量;二是由于故障后,外送通道被削弱,外送系统输电能力急剧下降。因此,提出了严重故障后火电机组和风电机组的优化切机方案。西北某电网的仿真结果表明:该优化切机方案在保证故障后系统安全稳定运行的基础上,能显著降低系统稳定恢复所需切机量,改善故障后系统恢复特性,大大提高系统运行的安全性和经济性。
