In order to improve the maintenance efficiency, SGCC put forward the remote centralized maintenance mode. The centralized monitoring is the essential business of centralized maintenance, it collect the vast amounts of information from nationwide smart grid dispatching and control systems, and provides monitoring pictures for the users who need understand the global running state of the systems. How visualizing the huge information in the limit screens is a problems to be solved. This paper introduces the application of pixel-oriented visualization techniques in the centralized monitoring, takes the nationwide state estimation rate monitoring for an example, and compare with original techniques. Through the research and application, we find that using pixel-oriented visualization techniques could make centralized monitoring more effective.
