摘要随着电力行业的日益繁荣,现代社会对电力系统实时信息掌握的快速性日益提高，对于潮流计算，这一获取电力系统电气信息量的基本而重要的手段，很有必要研究出一款可以人机交互的具有良好的可视化界面的软件来服务于潮流计算，使得潮流计算更加的智能化、直观化和快速化，这样才能满足现代社会对于信息掌握的快速性和方便性的要求。61710

    目前，国内外已经涌现出很多电力仿真和计算的软件，比EMTP、BPA、PSCAD等，在电力系统的各种分析和研究中起到了很大的作用。但是这些软件都有一个通病，就是软件的可视化程度不高，软件的人机交互的友好性不够，虽然它们在潮流计算等方面具有一定的精度，但是其晦涩复杂的界面和输入输出系统使得这些软件在使用时很不方便，未使用者必须经过专业的学习才能掌握它们，从而造成了一定的时间和精力的浪费。

对于现状，笔者开发了一款基于Visio2003 的可视化的潮流计算软件，在一定程度上弥补了传统的电力分析软件的不足，下面这方面的工作做一个简要的介绍：

1）建立了各种电气元件库，比如发电机，变压器等等，每个元件都有自己相应的电气属性，并且具有良好的参数修改界面；

2）通过对visio里的图元的shape的属性的调用实现了对电力拓扑的识别和系统的导纳矩阵的形成；

3）运用基于PQ分解法的原理编制了潮流计算程序；

4）最终的结果通过excel表格显示出来，并且在电力拓扑图上进行自动标注。

经过多次试验证明，本软件具有良好的精度和友好的人机交互功能，可以在一定程度上弥补传统的电力计算软件的不足，同时也说明了通过对visio的二次开发来实现电力系统的潮流计算软件这一条路是可行的。

Title The Development of Visualization for Power Flow Calculation     

Abstract With the growing prosperity of the power industry, the modern society has a greater eager to grasp the power system real-time information quickly.As for the power flow calculation ,a fundamental and important way to get the electric information of power system, it is necessary to come up with a can of software with HCI and  good visual interface to serve the power flow calculation .The software can make flow calculation more intelligent, intuitive and fast ,so as to meet the requirements of a quick and convenient grasp of the information of the modern society .

At present, a lot of software for power system simulation and calculation such as EMTP, BPA, PSCAD , have emerged at home and abroad .They have played an important role in a variety of power system analysis and research. But these software have a common problem, that is, the visualization and  the HCI of these software are not friendly enough, despite their certain precision for flow calculation. Their complex interfaces and input-output system make them inconvenient to use. The user who has never used them must go through professional learning to master them, resulting in a certain amount of time and effort wasted.

For the current situation, the author developed a flow calculation software

with visualization based Visio2003, making up the shortage of traditional power system analysis software to some extent . Next, the author will has a brief introduction for his work.

1)Establish the library for various electrical components, such as generator, transformer, etc. Each component has its own corresponding electrical properties, and has a good interface for parameter modification.

2)By calling the property of the primitive shape in Visio, we have completed the realization of the power system topology recognition and got the admittance matrix.
