基于最小二乘法的湖北电网舞动区域分布图局部订正研究

Research on Partial Revision in Hubei Power Grid Galloping Region Distribution Map Based on Least Squares

为了适应湖北电网高效智能精细化管理,需建立湖北电网舞动区域分布图的智能绘制模型,考虑到舞动区域分布与地形起伏度具有密切的相关性,绘制模型中采用最小二乘法进行一元线性回归,分析舞动区域与地形起伏度的相关性,建立地形起伏度订正模型,完成湖北舞动区域分布图的局部订正。结果表明订正模型精度较高,符合湖北省输电线路舞动实际情况。

In order to adapt to the Hubei fine grid intelligent and efficient management,the need to establish a smart grid drawing model Hubei dancing area distribution,taking into account the distribution of dancing and undulating terrain of the area is a close correlation between the model used in drawing conducted a least squares linear regression,correlation dancing and topography of the area,the establishment of a revised model of the topography,the completion of the regional distribution of local dancing Hubei revised figure. The results showed that the revised model of higher precision,more in line with the actual situation of Hubei transmission line dancing.
