摘要
电力系统专业计算软件在电力系统中有着十分重要的作用。电力企业的经营者们需要单独购买这样的专业计算软件,由于这样的计算软件使用复杂,需要大量的专业人员和专业培训,并且由于各个地区购买的专业计算软件不同,而且需要维护自己的硬件系统,其数据格式也各不相同,使得相互的电网数据、计算程序的共享和维护都十分困难。由此可见,传统的电力系统专业计算软件已经不能满足用户的需求。
     综合考虑了以上的功能需求,我们设计了基于Web的电力系统网络计算系统。它在设计上采用了基于Web的多层分布式结构。客户端采用了浏览器担当网络应用系统的前端。它彻底的解放了客户端,用户不需要安装任何客户端应用软件。并且它利用了Java强大的图形功能,使得使用界面非常友好和易于使用。服务器端建立起了分布式计算的中心,负责与各个计算模块的互联和通信。使得相互的信息共享和系统维护变得更加简单。
     用户只需要一台接入Internet的计算机,通过浏览器登录安装了本系统的服务器,便可以完成电力系统的专业计算。随着本系统开发的完善,它必将在很大程度上替代了以前客户端计算软件的功能。
     软件的每一次升级只需要在服务器端进行,用户端每次下载的都是最新版本,真正做到了“一次安装、到处运行”。节省了大量维护工作。并且同时可以在网站上提供基于Web的在线帮助,大大减少了培训费用。对于非电力系统的用户,也可以登录网站进行自学和接受专业培训,大大提高了电力系统专业软件的利用率。
The professional computing software of power system is playing a vital role in power system. The operators in power enterprises often purchase this kind of software individually. Due to the complexity of using the software, a considerable number of well-trained professionals are compulsory for power enterprises. What's more, because of different computing software and hardware systems, it's very tough for power enterprises to share data of electric network and computing software. Therefore, traditional computing software is incapable of meeting the demand of present power enterprises.
    Taking the above factors into account, we designed the Web-based graphic network computing system, which adopted the Web-based multi-tier distributed frame. On one hand, the web browser was adopted as the client side of the computing system, which is able to avoid the users' inconvenience by not installing any client application. Furthermore, the software has a very friendly GUI (Graphic User Interface) and is easy to use by applying the powerful functions of Java in graphics display. On the other hand, the computing hub was established on the side of server. It's very easy to exchange information and system maintenance because the hub is in charge of the interconnection and intercommunication.
    By using a computer connected to Internet, users are able to make professional computations when logging in the specified server. With the development of the new computing system, the traditional computing software will be replaced to a great extent.
    The new computing system just needs to be updated on the server side. The users can always obtain the latest edition. The workload of system maintenance can be reduced tremendously. And meanwhile the Web-based online help documents are available so that the cost of training is also reduced enormously. For those who are not professionals in power enterprises, they can log in the computing server and receive professional training. So the use rate of the professional computing software is eventually increased.
