外网等值模型必须跟踪外网运行方式的变化以确保地调EMS应用软件的计算精度。为提高地区电网EMS应用软件的实用性,作者开发了自适应的外网等值自动生成系统。该系统利用IEC61970CIM(CommonInformationModel)标准从省调EMS系统读取电网模型和实时数据,然后自动为地区电网生成外网等值模型,并按IEC61970CIS/CORBA(Component Interface Specification/Common Object Request Broker Architecture)规范通过广域网将外网等值模型发送至各地区电网,供地区电网EMS/DTS应用软件使用。该系统的外网模型可灵活定制,可在外网中自动生成或人工指定缓冲网,以满足等值精度和计算速度的要求。该系统实时自动运行,可随时为地区电网提供外网等值模型和相应的实时数据,大大提高了地区电网EMS/DTS应用软件计算结果的正确性。
External network equivalent model must track changes in the operation of the external network to ensure that the ground tone EMS application software calculation accuracy. In order to improve the practicability of EMS in regional power grid, the author developed an adaptive automatic equivalent system of external network. The system uses IEC61970CIM (CommonInformationModel) standard to read the grid model and real-time data from the provincial EMS system, and then automatically generates the equivalent model of the external network for the regional grid and complies with IEC61970CIS / CORBA (Component Interface Specification / Common Object Request Broker Architecture) The WAN equivalent model is sent over the wide area network to the regional grids for use by the regional grid EMS / DTS applications. The external network model of the system can be flexibly customized, and can be automatically generated in the external network or manually designated buffer network to meet the requirements of equivalent precision and calculation speed. The system runs automatically in real time and can provide the external network equivalent model and the corresponding real-time data for the regional power grid at any time, which greatly improves the correctness of calculation results of EMS / DTS application software in the regional power grid.
