摘要/Abstract

摘要： 随着电网规模的扩大和数据量的增多,需要一种高效直观的技术手段来实现对电网运行状态的监控和及时预警,电力系统可视化技术在这种背景下受到了人们的广泛关注。通过OpenGL和VC++的混合编程,实现了电力系统潮流动画、电压等位图、预警可视化的绘制,并开发了综合安全预警可视化系统,能够将电网的潮流分布情况、电压分布情况、越限及高危元件信息以动画、图形的方式生动形象地显示在屏幕上。该系统已成功运用于国内某电网,通过人机界面的交互,给调度人员的工作带来了极大便利。

Abstract: With the power system expansion and the increase of the amount of data, highly effective and intuitionistic techniques need to be achieved for the monitoring and safety warming of the system. Therefore, power system visualization techniques are highly concerned in this background. A method to achieve safety warning visualization by drawing power flow animations and voltage bitmaps was conducted by hybrid programming of OpenGL and VC++. Besides, a comprehensive safety warning visualization system was developed, by which the power flow distribution, voltage distribution and the information of out-of-limit and risk component on the screen can be revealed vividly. This warning system has been successfully applied to one domestic grid. Through the interaction of man-machine interface, it does bring great convenience for the dispatchers’ work.

Key words: power system, OpenGL, power flow animation, voltage bitmap, safty warning, visualization, dispatching, drawing
