摘　　要：由于PSASP和BPA等电力系统仿真软件的广泛使用,并且SCADA覆盖了江苏电网内主要运行设备,因此可以将SCADA实时数据作为建立电力系统仿真软件潮流反演数据包的数据源。本文基于江苏电网的SCADA系统,研究开发了一种数据转换软件可以方便快速地将电网某个时间断面下EMS中状态估计后的SCADA实时数据转换成电力系统仿真软件的数据包进行潮流反演。算例结果表明了基于SCADA实时数据电网潮流反演数据转换软件的正确性,并能有效节省大量工作量。Since the power system simulation software,such as PSASP and BPA,are accepted widely and the equipment in main power grids has been overlaid by SCADA in Jiangsu,the real-time data from SCADA can be obtained as the data source to construct the data package of the simulation software to replay power flow.In this paper,the data conversion software which quickly converts the real-time data after state estimation from SCADA in EMS to the data package of simulation software was programmed.The calculation results showed that the software is effective and helpful in workload saving.
