摘要/Abstract

摘要： 如何进行大风故障预警及停运概率的准确计算,对于提高电力系统预防风偏闪络和断线停运的能力具有积极意义。基于绝缘子风偏计算模型和极端风速的g-h分布模型,提出了电网大风停运概率计算的新方法。该方法首先通过绝缘子风偏模型计算风偏角和最小空气间隙,并建立了小空气间隙和风偏故障概率的线性函数关系;进而提出基于g-h分布的大风灾害下电力线路的断线概率计算方法。安徽电网的实际数据的计算结果证明了方法的有效性。因此建立有效的风偏计算模型和大风分布模型对预防大风停运具有重要作用。

Abstract: Wind faults early warning and trip probability calculation has a positive significance for power system defending windage yaw flashover and transmission line outage. This paper presents a novel algorithm for calculating wind trip probability based on calculation model of windage yaw and g-h distribution model. Firstly, windage yaw angle and minimum air gap are computed according to the calculation model of windage yaw of insulator string. The linear relationship between minimum air gap and probability of windage yaw flashover is established. The calculation method for probability of transmission line outage under gale disaster is further proposed based on the g-h distribution model. Historical data of transmission lines in Anhui power grid verify the correctness and efficiency of proposed method. Establishing calculation model of windage yaw and gale distribution model are important to prevent gale outage.

Key words: insulator string, windage yaw flashover, minimum air space, g-h distribution, wind trip probability
