Abstract:  In order to solve the problems of the realtime and convenience of operation status and monitoring index of plant operation monitoring system, a method was presented for the Web publishing of monitoring system of power plant based on AJAX. SVG was used as the Web publishing and display format of graphics system. In order to solve the problem of information’s realtime dynamic refreshment, the AJAX was elected as the asynchronous communication mechanism. The application results show that this method has the advantages of saving network bandwidth, reducing transmission delay and flashedfree of page updates. Operation officers can easily learn the operation status of the power plant unit through Web browser. It’s benefit for the coordination of government, grid state, power plant.
Key words: asynchronous JavaScript and XML(AJAX); monitoring system; scalable vector graphic (SVG); asynchronous communication; Web publishing
