摘要
利用简单的二维展示来进行上海电网电能质量全方位监测已经略显无力,迫切需要建立具有三维显示和分析功能的电能质量监测场景,但是采用当前的方法进行电能质量监测时,无法建立电能质量监测点与线路间的关联性二维矩阵,存在电能质量监测精度低的问题。为此提出一种基于GIS坐标结合Unity3D展示的电能质量监测方法。该方法先将地理坐标依次导入到Unity3D中,获取网格间的拓扑连接关系,组建监测关联矩阵,给出各个监测点的扰动方向,设定扰动源位置判别阈值,给出电能质量指标变化趋势,由此实现电能质量监测。仿真证明,所提方法监测效果较为全面,为实现电网电能质量全方位监测奠定了结实的基础。
This paper presents a quality monitoring method of electrical power combined with Unity3D based on GIS coordinate. At first, this method successively imported geographical coordinates into Unity3D and obtained topological connection relation between grids. Then, the method built monitoring correlation matrix and gave disturbance direction of each monitoring point. Moreover, the method established discriminate threshold of disturbance source and gave change trend of electrical power quality index. Thus, we realized the monitoring of electrical power quality. Simulation result verifies that the proposed method has more comprehensive monitoring effect, which lays a solid foundation for realizing power grid quality monitoring.
