Internet display system: real-time consumption tracking via Internet

Informational technology (IT) plays an important role in the power system industry. The World Wide Web (WWW) has become a convenient way to access information because the Internet browser integrates different network services into a common easily accessible user interface. This paper presents the Web-based real-time electricity demand metering, made for the first time within one electricity company in South East Europe. An example of the integration of the existing SCADA software with the advanced network technologies is presented. Authors selected Visual Basic, PHP (PHP: hypertext preprocessor) and MySQL database as development tools. The choice of PHP offers powerful features such as the zero client installation and on-demand access. The application is implemented on the basis of three-tier client/server architecture and up-to-date Web technologies. The access to data is available from any location 24 hours per day by using Web browsers
