Thermal Load Graph Analysis Method Based on Cubic Convolution Interpolation

为提高电网设备运行状态分析水平,本文研究了基于热力地图的负载分析系统。本文引用三次卷积插值算法实现热力图的可视化分析;基于设备负载率建立数据分析模型,并在百度地图和电网地理接线图的基础上设计了交互式的可视化分析界面。以某电网设备运行数据为例,对数据进行提取、处理和分析。结果表明:问题设备可以在地图上一目了然的展示出来,便于工作人员识别分析,从宏观上展示了设备的负载分布情况,根据其运行状态进行可视化分析,快速锁定问题区域和设备,提早采取电网检修工作,避免造成电网资源的损耗和浪费。

In order to improve the analysis level of grid equipment operation status,this paper studies the load analysis system based on thermal map.In this paper,the cubic convolution interpolation algorithm is used to achieve the visualization of thermodynamic maps.The data analysis model was established based on the equipment load rate,and an interactive visual analysis interface was designed based on the Baidu map and the geographical wiring diagram of the power grid.Taking the data of a grid equipment operation as an example,the data is extracted,processed and analyzed.The final research results of this paper show:The problem equipment can be displayed on the map at a glance,which facilitates the identification and analysis of the staff and shows the load distribution of the equipment from a macro perspective.Visual analysis based on its operating status,quickly locking up problem areas and equipment,and early adopting power grid overhaul work to avoid wastage and waste of power grid resources.
