当今社会是一个信息社会,一个知识经济时代。自世界上第一台计算机ENINC(Electronic numerical integrator and calculator)于1946年在美国问世到现在,计算机业飞速发展,技术淘汰指标高的惊人,价格下降以及软件应用的快速扩展引发了以信息处理计算机化为标志的“微机革命”,随之而来的是以全球信息网络普及和全球信息共享为标志的“全球信息网络革命”的蓬勃兴起。可见,世界已进入在计算机信息管理领域中激烈竞争的时代,计算机已经变得普通的不能再普通的工具,如同我们离不开的自行车、汽车一样。我们应该承认,谁掌握的知识多,信息量大,信息处理速度快,批量大,谁的效率就高,谁就能在各种竞争中立于不败之地。
电力一直是国家经济发展的主要能源,个人生活离不开的能源,但是不同的配电方式影响着电力效能的高低。本文就是要设计开发一款城市中压配电网典型接线模式可靠性分析系统,实现系统管理,包括登陆、退出;接线方式管理,包括五种树型接线方式和一种环型接线方式。
本系统是采用sql server 2000作为后台数据库,vc++ 6.0工具来设计程序,利用ado技术来把应用程序与后台数据库相连接。

Abstract
Today's society is an information society, a knowledge economy. Since the world's first computer ENINC (Electronic numerical integrator and calculator) appeared in the United States in 1946 to the present, rapid development of the computer industry, technology out of the prohibitively high index, prices and software applications led to the rapid expansion of information-processing computer marked by the "computer revolution", followed by global information and global information sharing network for the universal sign of "global information network revolution," flourished. Shows that the world has entered the field of information management in the computer era of fierce competition, computers have become common tools can not be normal, as we can not do without a bicycle, car. We should recognize that one who has mastered the knowledge of many large amount of information, information processing speed, high-volume, whose efficiency is high, who will be able to compete in a variety of invincible.
