无人值班变电站中,静态间隔图的维护难度大和画面响应速度慢决定其难以适应大电网监控系统的发展需要。在大电网集控中心数据采集与监控(SCADA)系统中实现不依赖于独立图形参数或文件的间隔图自动生成功能十分必要。文中深入分析了间隔图自动生成的关键技术,包括间隔图模版和图库自动关联,并给出了自动生成间隔图的2种实用方法,即基于实时库关键字和基于可缩放矢量图形(SVG)技术的间隔图自动生成方法。
In unattended substations, the maintenance of static interval map is difficult and the response speed of the screen is slow, which makes it difficult to meet the development needs of large power grid monitoring system. It is necessary to realize the automatic generation function of the interval graph independent of the independent graphical parameters or files in the SCADA system of a large power grid. In this paper, the key technologies of automatic generation of interval map are analyzed in detail, including the automatic association of interval template and gallery, and two practical methods of automatically generating interval map are given based on real-time library keywords and based on Scalable Vector Graphics (SVG) Technology automatically generated interval map method.
