摘要
根据配电网具有辐射状、弱环网和三相不平衡的特点,在已有前代回推的基础上,结合多端口混合补偿技术,实现了三相潮流和非接地故障计算的统一。且将接地故障进行单独处理,这样就避免了一般潮流和故障统一计算中由于接地点电压为零引起的计算不收敛现象。同时针对配电网中存在一个或者多个PV节点的情况,提出了对PV节点进行补偿的方法。
This paper proposes an approach to realize the integration of the calculation of three-phase power flow and ungrounding faults.This approach is based on forward and backward sweep method,considering characteristics of distribution system and multi-port compensation technology.In order to avoid calculation divergence when the grounding voltage is zero,the grounding fault is dealt seperately.Also,this paper presents a compensation method for PV node.
