配电网可视化供电能力计算软件的开发及应用

利用VisualC 6.0开发了可视化供电能力计算软件。阐述了软件开发的总体架构和模块划分及软件的功能特点,并用具体算例进行验证。该软件借鉴PowerWorldSimulator软件的风格,应用二维可视化技术,可以连续计算配网系统潮流,应用各种颜色显示各种元件不同的运行状态,采用饼图表示线路潮流的负载率,箭头表示线路潮流的大小和方向,节点电压可随运行状态变化,开关状态、电源出力以及负荷都可以在线改变。运行过程中如果出现线路过载或电压越限都采用醒目的颜色或数字显示。结果表明此软件可视化程度较高,界面全部汉字化,方便调度运行人员使用,实用性较强。

Application and Development of the Visual Software for the Load Supply Capability Computation of Distribute Network

A visual software for the Load Supply Capability(LSC) is developed by using Visual (C ) 6.0.The total framework,the module division and the function characteristic of software development are described in this paper,and a case in point is used to prove it.This software follows the style of PowerWorld.By using different colors to indicate different states of components,this software also utilizes cake chart to show load rate of circuit power and the arrow point to express the size and direction of the circuit power flow.The nodal voltage can vary with operation state;switch state,power and load can all change online.If circuit overload or voltage goes out of limit,it adopts striking color or digital display to give alarm.The result indicates the visual degree of this software is relatively high.All these interfaces use Chinese characters so it is easy for management and running personnel to use such a software of high practicability.
