【摘要】：电力工业业是关系国计民生的重要行业。面对电网中复杂的生产管理状况,电网工作人员需要及时全面的了解电网运行中的各种信息,其中,有功、无功、负荷等实时数据是最为关键的部分,它能反映出电网的实时运行状态与健康状况。但实时数据具有数据量大、变化速度快、不易观测等特点。以可缩放矢量图形(Scalable Vector Graphics, SVG)作为电力系统一次接线图和地理接线图的图形格式进行实时数据的动态显示是一种有效方式。但是目前的方案中明显存在着一些不足,比如关键信息不突出,数据是“被动”实时,网络传输消耗大等,并不能满足实际的需求。本文从电力行业中实时数据的应用出发,依托于输变电设备状态可视化智能管理平台的建设需求,研究相关的实时数据动态显示技术。实现了基于SVG的电网实时数据动态显示系统。通过电力SVG技术展示电力一次接线图,并以此作为载体,动态的呈现实时数据以及相应历史数据。使用划分专题图层和配置报警策略的方式,明确突出各监测主题中的关键信息与不安全状态。同时采用服务器推送技术,变服务器的“被动”响应为“主动”推送,提高了数据的实时性,并减少了数据传输量。采用J2EE的系统架构,提供了良好地稳定性、可移植性、灵活性、易维护性机制。论文成果已在输变电设备状态可视化智能管理平台投入使用,并取一定效果。应用表明,通过实时数据的动态显示,工作人员可以及时的把握所关心的数据,进行针对性监测,提高了工作效率,这也验证了论文成果的正确性与有效性。
[Abstract]:Electric power industry is an important industry related to the national economy and people's livelihood.In the face of the complex production management situation in the power network, grid workers need to understand all kinds of information in time and comprehensively in the operation of the power grid. Among them, real-time data such as active power, reactive power, load and so on are the most critical parts.It can reflect the real-time operation state and health condition of the power grid.It is an effective way to dynamically display real-time data with scalable Vector graphics (SVG) as the graphic format of primary wiring diagram and geographical wiring diagram of power system.But there are some shortcomings in the current scheme, such as the key information is not prominent, the data is "passive" real-time, the network transmission consumption is large, and can not meet the actual needs.Starting from the application of real-time data in power industry, this paper studies the related real-time data dynamic display technology based on the construction demand of the state visualization intelligent management platform of power transmission and transformation equipment.The real-time data dynamic display system based on SVG is realized.The power primary wiring diagram is displayed by power SVG technology, which is used as a carrier to dynamically present real-time data and corresponding historical data.By dividing the thematic layer and configuring the alarm strategy, the key information and unsafe state in each monitoring topic are clearly highlighted.At the same time, the server push technology is used to change the "passive" response of the server to "active" push, which improves the real-time performance of the data and reduces the amount of data transmission.The system structure of J2EE provides good stability, portability, flexibility and maintainability mechanism.The results of this paper have been put into use in the intelligent management platform of transmission and transformation equipment, and some effects have been obtained.The application shows that through the dynamic display of real-time data, the staff can grasp the concerned data in time, monitor the work effectively and improve the work efficiency, which also verifies the correctness and effectiveness of the paper.
