摘要(Abstract):
风电场通常包括多台同类型的风电机组,在大电网仿真计算中需要将风电场等值,以减小仿真规模并保证仿真的准确性。提出了基于风电机组低电压穿越特性的风电机组倍乘等值台数确定方法,该方法主要考虑了实际风电场中各风电机组出力不同对风电场等值的影响,基于双馈、全变流类型风电机组在低电压穿越期间的有功、无功控制策略,确定比较合理的等值机组台数,最后将风电场等值为多台出力相同的风电机组。通过对实际风电场的仿真分析表明,在不同控制方式下,综合考虑不同电压跌落水平的有功、无功最佳等值台数是一个范围,进而可以综合确定一个等值台数,以兼顾准确性和保守性。一般情况下,离线仿真可选择最小可能台数,在线仿真可选择有功最佳台数范围内的最小台数。
