摘要 覆冰严重威胁输电线路的安全稳定运行,获得实时的覆冰环境参数,开展覆冰预测研究是输电线路防冰、减灾工作的基础。旋转多导体法是一种常用的覆冰环境参数测量方法,但该方法在导体直径选择上一直没有完善的理论依据。该文根据旋转多导体法基本原理,建立旋转多导体覆冰增长计算模型,对旋转多导体表面的水滴碰撞、冻结等过程进行数值模拟,分析旋转导体在不同直径、不同环境条件下的覆冰增长规律,量化各环境参数对旋转导体覆冰增长速率的影响特性,提出一种可靠的旋转多导体直径的选择方法。结合仿真结果得出:不同环境条件下不同直径旋转导体间的覆冰速率差异性不同,多导体直径选择需兼顾的主要条件为最大化不同直径导体间的覆冰速率差异,使得导体覆冰速率能随覆冰环境参数的改变而灵敏变化。

Abstract:Icing seriously threatens the safe and stable operation of transmission lines. The research on icing prediction and obtaining environment parameters is the basis of anti-icing work of transmission lines. The multi-rotating conductor method is usually used to measure the icing environment parameters, but there is no perfect theoretical basis for the selection of conductor diameter. According to the basic principle of multi-rotating conductor method, an icing model of rotating conductors was established in this paper. The processes of water droplet collision and freezing on rotating conductors were simulated. The icing law of rotating conductors with different diameters and under different environmental conditions was analyzed, and the effects of various environmental parameters on the icing rate of rotating conductors were quantified. A reliable method for selecting the conductor diameter was proposed. Based on the simulation results, the method indicates that the differences of icing rate of conductors with different diameters changes with the change of environmental conditions, the selection of conductor diameter should be set to maximize the difference of icing rate between conductors with different diameters, and make conductor icing rate change sensitively with the change of environment parameters.
