包括基于热力学机理、流体力学机理和实测数据模拟等建立起的数学模型

并分析对比了其优缺点;其次

介绍了目前覆冰导线在线监测技术

包括视频监测技术、力学载荷计算监测覆冰厚度、倾角变化监测弧垂等技术;最后

指出了现有覆冰监测技术的一些不足之处

并提出了一些改进意见。

Abstract

Ice coating on transmission lines harms the safe and stable operation of power grids.This paper introduces the existing prediction models of icing process on transmission lines

including the mathematical models based on the mechanism of thermodynamics

the mechanism of fluid mechanics

and the measured data simulation

analyzes and compares their advantages and disadvantages.And this paper discusses the on-line monitoring technologies of iced conductors

such as the video surveillance technology

the ice thickness monitoring technology via calculation of mechanical load

the sag of line monitoring technology via calculation of inclination variation.In addition

some insufficiencies in the existing ice coating monitoring technologies are argued

and some improvements are suggested.
