摘要(Abstract):
配电网络重构和无功优化等场合涉及大量的潮流计算,而现有配电网潮流计算方法大多采用迭代法,其迭代过程消耗大量的时间,增加了计算负担。为提高潮流计算的效率,在定量分析配电网简化条件的基础上,采用2种简化方法对ZIP负荷模型进行线性化,提出了基于2种线性负荷模型的线性单相潮流计算方法(linear single-phase power flow method,LSPF)和线性三相潮流计算方法(linear three-phase power flow method,LTPF)。采用多个三相平衡和三相不平衡测试系统,分别对2种线性单相潮流计算方法和线性三相潮流计算方法的计算性能进行了测试与比较。
