智能电网调度控制系统图形广域维护与浏览技术

随着电网互联和特高压交直流混合跨区输电的快速发展,电网运行特征发生了深刻变化,对大电网运行监控画面也提出了新要求。文中针对现有智能电网调度控制系统画面浏览方式无法满足在同一幅画面中集中监视跨调度机构的特高压联络线的问题,提出一种电网图形广域维护和浏览方式。该方式通过引入设备模型广域检索、广域文件统一管理和推送、画面广域模型的定义和维护、实时画面广域浏览等技术,实现特高压互联电网关键设备的一体化监视。该技术已在调控中心试点应用,满足送受端国调分中心、省调对特高压跨区交直流设备运行状态和运行风险提示的实时监控需求。

Graphics Wide-area Maintenance and Browsing Technology for Smart Grid Dispatching and Control Systems

With the rapid development of grid interconnection and ultra-high voltage(UHV)AC/DC interconnected power grid, the characteristics of grid operation have undergone profound changes and new requirements have been proposed. In view of the problem that the current graphics browsing of smart grid dispatching and control system is incapable of meeting the requirements on centralized monitoring of UHA line equipment belonging to different dispatching institutions in the same picture, a method of grid graphics wide-area maintenance and browsing is proposed. The method realizes integral monitoring of crucial equipment by introducing the equipment model wide-area retrieval technology, the wide-area graphics file unified management and pushing technology, the definition and maintenance of wide-area data technology and the real-time graphics wide-area browsing technology, etc. The scheme has been pilot applied in the control center. This method can provide technical support to the operation of UHV interconnected power grid, and meet the demand for real-time monitoring of operation state and operating risk prompted by UHV DC equipment.
