Key technology for smart grid dispatching aided decision

Aimed at the "growing information flood" caused by the power energy management system, this article presents a solution with three functions: the multi-dimensional analysis when the power grid at normal state, the visualization display at abnormal state, and the intelligent fault analysis at fault state. According to these three functions, correspondingly presents three key technologies: the CIM+GPS+GML+SVG modeling method for power equipment and spatial information, the visualization method for power grid abnormal information, and the rapid fault recognition method based on the power flow translation factor.
