摘要: 针对强台风环境下配电线路故障问题,提出了一种台风到来前配电线路故障概率评估方法。首先,根据历史灾害损失数据拟合强台风环境下的杆塔故障概率曲线;其次,利用流体力学软件对配电网所在区域进行风荷载仿真计算;最后,在真实台风环境下根据台风实时气象信息计算配电网所在区域的风荷载,并计算配电线路整体故障概率。算例验证了强台风环境下该方法对配电网线路故障概率评估的合理性和实用性,该方法可为中国东南沿海配电网台风期间应急预警及防灾减灾工作提供借鉴参考。

Abstract: An outage probability evaluation method of distribution line under typhoon is proposed in this paper. First, the probability curve of the tower fault of the 10 kV distribution line is fitted according to the historical typical typhoon data. Secondly, the wind load in the area of the distribution network is simulated by the hydrodynamics software. Finally, based on the wind load calculated from the real-time meteorological information under real typhoon environment, the overall failure probability of the distribution lines are calculated. The simulation results verify the rationality and practicability of the method for the probability evaluation of the distribution network fault in the strong typhoon environment. The method can be used as a reference for emergency warning and disaster prevention of distribution network in southeastern coastal areas of China during typhoons.
