摘　　要：本文着重研究了配网合环系统之间相角差与环网阻抗,提出一种基于回推法的配网合环潮流计算方法;通过BPA仿真及实测数据验证了算法的有效性和准确性,利用误差分析和修正手段将适用性延伸至不同220kV变电站或不同500kV变电站的配网线路合环潮流计算。弥补了现有研究的空白和不足,有较高的工程实用价值,对广东电网推进配网合环工作极具指导意义。This paper focuses on the study of the phase angle difference between the closed-loop systems of the distribution network and the impedance of the ring network, and a method for calculating the power flow of the closed-loop network based on the backstepping method is proposed. Utilize error analysis and correction methods to extend the applicability to the calculation of closed-loop power flow of distribution lines of different 220 kV substations or different 500 kV substations. It makes up for the gaps and deficiencies of the existing research, and has high practical value in engineering, which is of great guiding significance for the promotion of the distribution network integration of the Guangdong power grid.
