Web‐based rural power monitoring system

Abstract

The electric power network in rural China is distributed over a substantial land area and has a very large number of transformer substations. It is difficult and expensive to monitor and control each substation manually. Therefore, it is important to be able to monitor the network remotely and this is best achieved using a real‐time, web‐based system. However, there is currently no good way to display the status of so many substations on a single web page and without time‐lapse or to manage each of the substations according to actual rural transformer substation topology. This paper offers a working solution to the above. First, we choose a new Scalable Vector Graphics (SVG) criterion using extensible Marked Language (XML) to communicate between client and server. This avoids bandwidth restrictions leading to time‐lapsed graphics, but not a traditional vector display method on web in geographical information system, such as JPG. Second, we create a web‐based framework based on Model‐View‐Control (MVC). Lastly, we develop and deploy a transformer configuration system for a Peking suburb to monitor and with it control about lapse graphics and show that it can support the functions of power network enlargement, zooming, and roaming. Our system enabled the monitoring and controlling of power substations in real‐time.
