摘　　要：本文首先推导了合环潮流的通用计算公式,并针对不同类型的配网合环,给出了合环潮流的实用计算公式。结合配网合环的实际情况,对这些公式进行分析和简化,分析结果用PSASP软件进行仿真验证,得到了不同合环方式下,合环回路参数对合环潮流的影响,为调度人员快速判断、计算和减小合环潮流提供了理论依据。In this paper,a general formula for calculation of closed loop power flow is derived firstly. Then, according to different types of closed loop,some practical calculation formulas are deduced. Combined with the actual situation,the formulas are analyzed and simplified. The analysis results are validated by the simulation of PSASP. Based on the results,the impact of closing loop parameters on the power flow under the different types of closed loop is concluded,which is a theoretic support for the dispatcher to quickly judge,calculate and reduce the closed loop power flow.
