摘　　要：分析和评估合环操作对辐射型中压配电网所造成的影响对配电网的调度和安全运行有着重要的意义。首先对某城市的典型中压配电网络进行研究,在其配电网原有SCADA/EMS和GIS系统上,提出适合于该配电网特点的合环操作分析系统的解决方案,采用基于IEC 61970/61968的公共信息模型(CIM)进行合环操作分析系统和原有系统之间的数据交换。合环潮流计算是合环操作分析系统的核心,本文采用叠加原理对合环潮流进行计算,使计算具有良好的收敛性,满足了系统在线运行的要求。Analyzing and evaluating to the effect caused by loop closing operations in radial medium voltage distribution networks are extraordinary important to the safe operations. This paper studies the radial medium voltage distribution in the specified city, and introduces the solution of the loop closing operation analysis system. The CIM model based on IEC 61970/61968 standards is used to realize the data exchange between the loop closing operation analysis system and other systems existed in the distribution. To the loop closing power flow calculation, which is the most important part in the loop closing operation analysis system, the superposition principle is involved ,which leads to better convergence property for the power flow calculation, satisfying the requirement for the system operating on line.
