Smart Grid Situation Awareness Diagram Modeling and Conceptual Design of Situation Awareness Visualization

提出了智能电网态势管理概念模型及概念设计,包括态势感知可视化对象建模及应具有的核心算法模块。态势可视化的核心是态势图建模,文中提出了态势图构成模型,并提出了实时态势图片生成以及基于条件触发的历史图片存储机制。存储的带时间戳的历史态势图片,经过拼图,可实现历史动态态势图动画反演播放;提出了未来的预测动态态势图的生成机制,生成的带时戳的未来态势图片,经过拼图,可实现未来动态态势图动画播放。初步探讨了态势图设计评价指标,指出态势底图的选择将直接影响到态势感应和感知可视化效果。

A conceptual model for smart grid situation management is provided together with the obj ect 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 j udgment 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.
