摘要
近年来,日常电网调度以及电网数据监视对实时化和自动化水平提出了更高的要求,当前电网模型难以满足日益增长的计算需求。通过分析现有电网调控数据采集与监控处理系统(supervisory control and data acquisition,SCADA)模型的功能局限性,以具体区域、供电区和厂站实例为对象,设计面向电网网络的模型。通过对使用模板公式计算前后的计算时间进行统计对比分析,证实了基于面向网络对象的模型开发的计算功能能够自动感知电网结构的变化,并实时动态调整计算模型,为实现由面向设备对象的监视转变为面向电网网络对象监视奠定了基础。
In recent years,daily power grid dispatching and grid data supervision have placed higher demands on real-time and automation levels,but current power grid models can hardly meet ever-increasing computing requirement.Based on an analysis of functional limitations of the existing SCADA(supervisory control and data acquisition)model,a model for power network was designed by taking specific zone,power supply area and plant station example as objects.Statistical comparative analysis of calculation time obtained before and after calculation was made with the template formula verified that the computational functions developed on the basis of a model aiming at network objects could automatically perceive changes in grid structure and dynamically adjust the calculation model in real time,thus laying a foundation for further transformation from equipment-oriented supervision to grid-oriented supervision.
