摘要

根据输电线路状态方程，分析了输电线路长度变化与线路实际运行状态，包括导线运行温度、导线等值覆冰厚度及风速的对应关系，提出根据导线实际运行状态计算输电线路实际长度的方法，并以东北某线路实际监测导线张力和导线温度数据验证了此方法的正确性。根据输电线路长度变化与线路实际运行状态的关系，建立了输电线路各点在不同状态下距线路首端距离的换算方程，最终将实际故障距离换算成故障点距线路首端水平距离。

Abstract

The relationship between the transmission line length and the operating states of transmission line， including the conductor temperature， equivalent icing thickness and wind speed， is analyzed based on the equation of state in transmission line. The corresponding method to calculate the transmission line length is also proposed by considering the operating states of transmission line. Correctness of this method is verified by the conductor tension and conductor temperature practical running data from Northeast China. Finally， the conversion equation is established according to relationship between the transmission line length and the operating states of transmission line， and then the actual distance to fault position is converted into the horizontal distance.
