随着电力系统的发展,系统日益扩大,数据量越来越大,要求系统运行时,调度人员对出现的问题快速反应,才能保证电力系统的安全运行.原有电力系统中的数据显示方式已经不能满足实际要求,利用现有的科学技术、计算机图形学,选取更有效的展示方法已成为迫切需要解决的问题.文章提出的可视化图形模型可以结合计算机图形学,为电力系统的数据可视化提供更好的方法.“,”With the development of power system,the system expands and the data increases day by day,it is necessary that the dispatchers have rapid reaction to the problems that possibly occur during the operation of power system so as to ensure its safety.The original display mode of power system data can not meet the actual requirements anymore,and how to select a more effective display approach by using the existing science and technology and computer graphics has become an urgent problem to be solved.The visual graphic model proposed in this paper can provide a better way for the visualization of power system data by using the computer graphics.
