摘要:
目前应用最为广泛的覆冰厚度计算模型主要是针对称重法原理,而垂直档距是该模型中非常重要的一个参量,参量取值的准确度对等值覆冰厚度的监测结果准确度具有决定性的影响。但在现阶段的工程实践中,现有的各个计算模型并未对垂直档距参量在线路运行过程中动态变化特性进行全面、深入的考量,因此影响了覆冰预警系统的应用效果。本文对垂直档距在输电线路运行过程中的动态变化特性进行了定性和定量分析,研究了冰荷载和温度变化对导线应力及垂直档距的影响,并通过数值仿真对其影响程度进行了评估,最终在此基础上提出了基于垂直档距动态变化特性的覆冰厚度计算策略,从而提高称重法测量输电线路覆冰厚度的准确度。
Abstract:
The most widely used icing thickness calculation model is mainly based on weighing method. The vertical span is an important parameter in icing thickness calculation model, and its precision decides the accuracy of the icing monitoring terminal monitoring results. But in the present engineering practice, the changing characteristic of the vertical span in power transmission line operation is not fully considered, which affects application effect of icing early warning system. In order to improve the precision of weighing method to measure the icing thickness on transmission line, the author carries out qualitative and quantitative analysis of the changing characteristic of the vertical span in line operation, researches the influence of ice loading and temperature variation on the stress of conductor and the vertical span, and evaluates its influence through the numerical simulation, finally puts forward an icing calculate method of icing thickness monitoring system based on dynamic characteristic of vertical span.
