【摘要】 随着电力系统规模的不断扩大，它的运行状态也越来越复杂多变，调度人员在工作中需要处理大量的数据，任务繁重。随着能量管理系统(EMS)高级应用软件的不断完善和计算机计算速度的不断提升，各种分析计算结果源源不断地产生；电力系统的发展(如系统互联、电力市场化)，也使得经济类数据大量地涌现出来。现有EMS中的数据显示方式已经不能满足实际需要。因此，如何合理地显示大量数据，减轻调度人员工作强度和提高工作效率，已成为急待解决的问题。可视化技术是八十年代后期随着计算机技术发展而出现的一个新兴研究领域。它的主要目的是更加有效的分析和处理越来越多的科学和工程数据，提高工作效率，促进科学和工程技术的发展。本文结合可视化技术与计算机技术，对电力系统参数的显示问题进行了深入的研究，设计了一个电力系统参数的可视化软件。本系统以Windows XP为开发平台，以Visual C++6.0为开发工具，数据库部分使用的是SQL Server 2000，以面向对象技术作为设计思想，采用模块化程序设计方法，具有一定的通用性。本文首先介绍了可视化软件技术的发展过程，结合电力系统自身的特点和实际要求，完成了电力系统参数可视化软件的总体框架，规划了本软件的组成模块以及各模块之间的关系；并将系统分为图形绘制平台和运行部分；接着对于系统各个部分所用到的关键技术进行了阐述，重点对面向对象技术、图形技术和数据库技术等进行了详细的说明。在图形绘制平台部分用到了图形技术，主要是运用GDI函数绘制基本的图元，并实现了图元的拾取、复制、粘贴等编辑功能；在数据库设计方面，重点介绍了视图与数据库接口方面的知识，通过ADO来连接图元参数与数据库里的数据；最后介绍了数据显示技术的实现，包括动态箭头的显示、饼形图的可视化和三维可视化的显示。在这些技术的基础上，实现了电力系统的潮流可视化和母线的电压幅值三维可视化，并结合运行实例，在IEEE 36节点的单线图上进行了验证。更多还原

【Abstract】 With the development of power system, its operating state is more and more complex. The operators need to deal with a great deal of data, whose tasks are heavy. With the improving of the application software of energy management system (EMS) and the increasing of the computer calculating speed, kinds of results come into being. The development of power system brings a great deal of economic data. The present method of displaying data cannot be satisfactory. So a good way is needed to display the data so as to improve the operators’ working efficiency.The visualization technology is a new research domain with the developing of the computer technology at the end of the 1980s. It is used to analyze and deal with an immense amount of information and to improve working efficiency.This paper carries through a deep research on the display of data in power system combining the visualization technology and computer technology, and has successfully designed the visualization software of data in power system. The system is designed regarding Windows XP as operation system, and Visual C++ 6.0 as developing tool, and SQL Server 2000 as database. The system have the characteristic of modularization, and have universal property, its planning idea is object - oriented technology.This paper mainly illustrates the design progress of the visualization technology and accomplishes the overall structure of the visualization software of data according to the features and requirements of power system, and makes out the composing modules and the relationships between them; The system is divided into two parts: configuring platform and running platform; Then the paper focuses on the key techniques used in each part of the system emphasizing the Object-Oriented technique, graph technique and database technique.Graph technique is mainly used in the part of graph configuration. It mainly refers to drawing with GDI functions, and carries out the functions of collect, copy, paste and so on; At the aspect of database it manly introduces the knowledge of the view and database interface , and connects the data between the figure and database using ADO; Finally, the paper introduces the technique of data display, including the display of dynamic arrows, pie and three-dimension. Based on these visualizations technologies, visualizations in the power flow and bus voltage three-dimension are implemented. The characteristics of software are shown in concrete application combining with running example on IEEE 36.更多还原
