Smart Grid Situation Awareness Diagram Modeling and Conceptual Design of Situation Awareness Visualization
Zhang Jian-mi · Dianli xitong zidonghua · 2014
A conceptual model for smart grid situation management is provided together with the object model of situation awareness visualization as well as the core algorithm.The core of situation visualization is the situation diagram modeling.A situation diagram constitution model is put forward,and a real time situation diagram generation scheme and a condition trigger storage scheme for historic diagrams have been designed.The stored historic diagrams with time stamp can be assembled for historic situation play back of historic situation explaining and reasoning.A graph generation scheme for future situation prediction is also presented from which future situation visualization is accessible.The judgment criterion for situation diagram is also discussed and it is observed that the base graph selection will have a serious impact on the performance of situation induction as well as situation perception.The engineering application theory and method under discussion have been applied in the electric power distribution network situation awareness visualization.
