Abstract:

电网故障时逆变型分布式电源(inverterinterfaceddistributedgenerator,IIDG)的不脱网控制策略决定了其故障电流,而传统等值模型未计及IIDG负序电流注入,造成含IIDG电网短路计算的局限性。文章分析了含IIDG电网短路计算原理,结合故障中IIDG序电流控制和无功功率支撑,建立IIDG短路计算序分量电流源模型。在此基础上,比较不同控制条件下多逆变型分布式电源(IIDGs)短路电流和端电压响应,揭示IIDGs短路电流与电网以及自身不脱网运行持续时间的关系,提出计及不脱网运行时序和序电流控制的多IIDGs电网短路电流的对称分量迭代算法。采用PSCAD/EMTDC软件仿真验证该方法的正确性。
