摘要
为提升大电网分析的自动化水平,获得更精确的电力系统计算分析模型,基于电网通用信息模型(common information model,CIM)提出了一种多粒度的电力系统潮流计算数据生成方法。首先,对CIM模型的拓扑连接关系进行分析并改造。然后基于图论方法,从抽象深度和电力系统运行状态两个方面,对潮流计算拓扑进行构建。最后结合实际电网CIM数据及DSP潮流计算软件进行验证,结果表明该方法能通过在线系统中的CIM数据生成不同粒度的潮流计算拓扑。
To improve the automation level of large power grid analysis and construct more accurate power system calculating topology,a multi-granularity power flow calculation data construction method based on common information model(CIM)is proposed.Firstly,the connection relationship of CIM topology is analyzed and reformed.Then,subject to different abstraction depth and power system operation state,the power flow calculation topology is constructed based on graph theory.Finally,the method is tested with actual grid CIM data and DSP power flow calculation software.Results show that the proposed method can provide different granularity power flow calculation topologies through online system CIM data.
