面向对象的可视化电力系统分析软件研究

摘要

The traditional programming technology is based onprocedure,which makes the software difficult to maintain and develop.The object-oriented programming is a new technology,which derives abstract classes from real objects and builds the program structure by means of heritage.It is more reasonable and easier to develop, and hence is an alternative to overcome the problems associated with the development,maintenance and update of large power system software.The visual programming technology improves the operation interface.The way to derive abstract program classes from power system devices is discussed and a program structure is introduced, which is based on object-oriented visual programming.It also pays much attention to the computational efficiency and operability.%传统的编程技术是基于过程的，使得软件难以维护和发展。面向对象编程是一种新的编程手段，它通过从真实对象中派生出抽象的类，并通过继承的方法来构造程序结构。程序结构更加合理，易于开发。因此，面向对象编程是克服大型电力系统分析程序难于维护、发展与更新的一种选择。可视化技术改善了操作界面。讨论了如何从电力系统装置派生出程序中抽象的类，介绍了一种以面向对象编程和可视化编程为基础，兼顾计算效率和易用性的程序结构。
