摘　　要：针对电网冰区分布图难以反映位于覆冰微地形区域线路的覆冰状况的问题,提出一种湖北电网覆冰微地形辨识方法。该方法首先明确山地划分标准,然后综合考虑坡向、山脊、临近水体等地形指标,以及线路走向、覆冰期主导风向等因素,最后得到覆冰微地形区判据,并以湖北典型覆冰微地形区为例验证。本方法对掌握湖北覆冰微地形分布规律,全面地考虑微地形对线路覆冰的影响,指导线路运维和在线监测设备布点均具有较大实际意义。In order to solve the problem that the icing distribution map of power grid cannot reflect the icing condition of the transmission line located in the icing microtopography area,this paper proposes an icing microterrain identification method for Hubei power grid. This method first defines the mountain land division standard,then comprehensively considers the topographic indicators such as slope direction,ridge and adjacent water body,as well as the line route and the dominant wind direction during the icing period,and finally obtains the criteria for the icing microtopography area,which is verified by taking the typical icing microtopography area in Hubei Province as an example. This method is of great practical significance for mastering the distribution law of icecovered microtopography in Hubei Province,comprehensively considering the influence of microtopography on transmission line icing,and guiding transmission line operation and maintenance and online monitoring equipment layout.
