SVG及其在电力系统软件图形化中的应用初探

对电力系统接线图等图形的灵活支持是目前电力系统应用软件应该具备的基本功能之一,传统的处理方法是开发专用的图形处理模块提供支持,限制了软件的灵活性和开放性。IEC61970标准统一了对电力系统资源的统一建模,以实现软件系统的开放和互操作,但并没有能涉及电力系统图形数据的统一建模。SVG(ScalableVectorGraphics)是基于XML的可扩展二维矢量图形格式,正逐渐广泛应用于Web上的图形数据开放式发布,具有广泛的应用前景,本文提出了将SVG应用于电力系统软件中以提升基于Web的电力系统应用的图形

Study of the application of SVG in power system graphicalized software

It is essential for the power system software to provide visualization of many kinds of graphics such as the power system network diagram. The traditional method to achieve this goal is to develop specialized graphical module, which makes the system less open and flexible. On the other hand, the IEC61970 provides a uniform modeling of the power system resource to realize the openness and interoperability of the software systems, but the interoperability of the graphics is not included. SVG(Scalable Vector Graphics) is a language for describing two-dimensional graphics in XML and makes the graphics sharable through Web.Based on a brief introduction of SVG, this paper puts forward the application of SVG in power system software to make its graphics system more flexible, open and interoperable through Web.
