Web-based Management Information System Relay Protection and Implementation


eb before and after the end of the scripting languages ​​can be mixed to achieve a variety of programming, and server-side scripts and client-side script mixed programming, Web application developers to shorten the time to ask. 4.2Web function within the system to achieve the current electricity network construction become more sophisticated,[link widoczny dla zalogowanych], more applications will be increasingly turning to the Web. In order to meet the needs of network users, network functionality of the system developed, the main purpose is to simple functions such as data query, the system uses the browser / server (B / S) mode. B / S mode do not need to develop client software, easy management and maintenance, development of high efficiency, short development cycle, system and platform-independent, is particularly suitable to query information-based information management system. Internet users access the server through the Web browser, the query and other operations,[link widoczny dla zalogowanych], these services request by the data packet to the server side, was captured ASP component that interprets and executes the corresponding script, access the database through the ADO object and returns the corresponding data that the same form of data packets back into the network on the user's browser display. To handle server-side script commands specific procedures, the need to install a script engine (ScriptingEngine) servers, such as: running on NT or Win2000 on IIS (IntemetInformationServer) or Win98 on the PWS (PersonalWebServer). Protected sectors of the system as a service system should be installed to run the power company's protection department LAN server, the Power Authority to provide network services. Internet users can visit after the Electricity Generating Authority of private network access the system through a browser page. Electrical machinery main function of the system's network components from the Web information management, Web server components and database components together to achieve three parts: 1) Web information management component is a Web services management background, the administrator of the components through the network users can add and delete account, set permissions to a user's query,[link widoczny dla zalogowanych], set the Web can be accessed through the device parameters and equipment protection configuration and setting, set the protection setting is available for download such notice. These settings are stored by the component in the database; 2) a database component is the core of Web services, Web services provide data to support its Web server component of the data processing request and reply; 3) Web service component is the Web service the subject of Internet users to access back-end database through which to obtain the necessary information. 5 system running effect of the system has been put into operation more than 1 year, made the following significant benefits: (1) implementation of the protection management computer, information technology, greatly improving the protection of professional management; (2) The management tools and the change in the way, save a lot of manpower, material, and now only have a staff sufficient to undertake all maintenance work; (3) enables information sharing, improved resource utilization; (4) greatly improved work efficiency; (5) directly serve the substation site work to meet the needs of all kinds of information, greatly improving the efficiency and quality of field work for the protection of safe and reliable operation of automatic equipment and provides an important guarantee. 6 Conclusion Web-based management information system network protection capabilities improve, simple, intuitive and efficient, both to meet the needs of power system protection work, but also as a modern power system protection as part of integrated management. In addition, the system also interfaces with other systems more easily and work together. Can be expected, Internet technology is to achieve protection management computer, information of the inevitable choice. References: 【1】 Lin Li, Jing Zhang, High Shu, Huang Zu Yi.
