新能源送出系统基于SVG缺相控制的暂态过电压抑制方法

Gaoya dianqi
针对新能源集中送出系统的人工接地短路试验和仿真结果表明，风电、光伏汇集线路发生单相瞬时接地故障后，系统在故障相分闸至重合期间存在暂态过电压，并已成为制约新能源送出能力的主要因素之一。文中基于对典型新能源集中送出工程暂态过电压的仿真计算和人工接地短路试验结果，分析了汇集线路故障发生及清除后暂态过电压的阶段性特征及其产生机制；研究了静止无功发生器（static var generator，SVG）在原有控制策略下的无功响应情况与系统过电压情况的关联性，分析了原有策略的缺陷 ...

低电压穿越场景下的构网型储能变换器功率协同控制策略

Gaoya dianqi
随着高比例新能源并网，构网型储能变换器在网侧电压故障期间，面临着暂态失稳和过电流的问题，对并网稳定造成严重威胁。针对这一问题该文首先建立不同工况下的暂态模型，分析了暂态功角失稳和过电流的原因。其次，在此基础上提出了面向低电压穿越场景下的有功—无功协同控制策略，通过电压跌落的在线辨识，结合输出侧相量关系，实现了对构网控制策略参考功率的分段自适应控制。最后，通过仿真和实验验证了所提方法对提升暂态稳定性、无功支撑及过电流抑制的有效性。
