Rendering Method of Galloping Distribution Map Based on Meteorological-Geographical Method

继频率法、舞动系数法之后,提出了基于气象地理法的输电线路舞动分布图绘制方法。在统计和分析输电线路历年来发生导线覆冰舞动情况的基础上,通过总结气象、地形特征规律,建立覆冰舞动的气象模型和地理模型;结合运行经验,提出舞动区域的分区、分级标准;建立舞动分布图绘制方法标准技术体系。最后,以某省为例采用气象地理法绘制了舞动分布图,并检验其与实际舞动情况的吻合程度,得出了该方法合理、正确的结论。

This paper presented the rendering method of galloping distribution map for transmission line based on the meteorological-geographical method following the frequency method and the galloping coefficient method. Based on the statistics and analysis on the icing galloping conditions of transmission line over the years, the meteorological model and geographical model were built for icing galloping, through the summary of meteorological and topographic features, laws. In combination with operation experience, galloping area partition and classification standard were put forward. The standard technical system of rendering method for galloping distribution map was established. Finally, this paper used the meteorological-geographical method to draw the galloping distribution map for some province, and inspected its matching with the actual situation, which could conclude that the method was reasonable and correct.
