Abstract


With the expansion of the scale of the grid, improve the management level, the power system needs of a variety of information dissemination and sharing are also increasing. The majority of EMS / SCADA system the lack of convenient information distribution system, a large number of grid information can not be shared. This is contrary to the development of the Internet and the power, does not meet the requirements of modern power development. With the wide application of network technology, the use of Web technology release information resources has become the development trend of information technology of the power system. This paper analyzes the current situation of the information release system, the shortcomings and deficiencies of the proposed distributed dynamic Web information dissemination module. The main research J2EE technology overall framework, an important part of the Java programming language and Java Database Connectivity technology. Was constructed based on the J2EE browser / web server / database server three-tier information dissemination module, through a browser from a Web server to download the JSP page that contains the JDBC calls, you can query, browse a variety of substation data, historical curve Information. It integrates Web, Java, JSP, JDBC, server, and database technology, to achieve a highly modular, cross-platform and client maintenance-free. In this architecture, the browser hypertext proposed to access the database to the Web server, the Web server accepts client request, the request into SQL syntax, and handed over to the database server, database server request data processing, and then return the result of the processing results to the Web server, the Web server will be once again transformed into the form of HTML documents forwarded to the client browser to display friendly form of Web pages. Information distribution system substation various measurement parameters are stored in the Microsoft SQL Server 2000 database and set to an ODBC data source, Java database applications can access a variety of ODBC data source through JDBC-ODBC Bridge. Application in JBuilder X compile, package after debugging, and image files such as voltage, current curve be deployed with WebLogic 8.1 server, to call for the end user's browser. The information distribution system based on J2EE structure, Web applications as the core JDBC-ODBC bridge driver mode to build a unified, convenient information exchange platform, the browser does not need to install any software,
