摘要(Abstract):
风电场聚合建模通常将整个风场按装机容量折算至一台机组。由于检修、弱风或故障脱网等原因,实际并网机组的数量将降低,引起聚合模型的误差。主要研究并网容量对直驱型风电场聚合模型误差及其对电力系统暂态稳定分析的影响。详细分析了故障期间低电压穿越(low voltage ride through,LVRT)策略对永磁同步发电机(permanent magnet synchronous generator,PMSG)外特性的影响。推导出了风电场在线容量与聚合模型误差之间的量化关系。通过仿真分析分别对比了不同在线容量时聚合模型在LVRT过程中有功功率、无功功率及恢复时间之间等输出量之间的误差。分析了具有可控功率源性质的PMSG接入对同步发电机功角稳定性的影响。结果表明,由聚合模型计算得出的系统暂态稳定分析的结论偏乐观。
