基于WebSocket的电力系统实时数据更新研究

摘要

Visualization technology has been widely used in power system, it utilizes the graphic perception ability of humanity to display equipment's operating status data intuitively, greatly improves the system management level and staff's operating efficiency. The real-time updating of the visualization data is the core part in visualization technology, this paper first elaborates the traditional data update mode, and discusses its advantages and shortcomings, then gives a solution based on WebSocket which a-chieves two-way communication to really accomplish the real-time data updating, finally gives an application example, and the key part of the code, to provide a basis for future research and application.%可视化技术在电力系统中已得到广泛的应用,其利用人对图形的感知能力,直观地展示设备运行状态的相关数据,大大提高了系统管理水平和运行人员的工作效率.可视化数据的实时更新是可视化技术的核心部分,本文阐述传统的数据更新方式,讨论其优、缺点,提出基于双向通信的WebSocket的解决方案,实现真正的实时数据更新,最后给出应用范例及关键部分的代码实现,为今后的相关研究、应用提供依据.
