摘要
我国华南沿海地区是台风登陆高频区,台风灾害会给电网造成很大损失。目前,电网企业仍然缺乏有效的台风测量和预警手段。针对沿海强风地区输电线路的台风观测对提高线路防风抗灾能力十分必要,基于激光测风雷达、三维超声风速仪和表面应变计等多种测量手段研究了沿海地区输电线路层面台风的观测方法。通过对"莫兰蒂"台风的实测分析,验证了本方法的可操作性,并获得了"莫兰蒂"台风大量的实测数据。通过对实测数据的深入分析,得到了"莫兰蒂"台风风速风向和脉动特性的变化规律。
Typhoon lands on southern coastal area of China in a high frequency,and it can cause great loss of the power grid.At present,the power grid enterprises still lack effective method for typhoon measurement and warning.Typhoon observation on transmission line in coastal area is very necessary for improving the disaster prevention and mitigation ability of power grid,the observation method of typhoon on transmission line level in coastal areas is studied based on laser wind-detecting radar,three-dimensional ultrasonic anemometer and surface strain gauge and other measuring equipments.This method is verified by the pratical measurement of the typhoon“Meranti”,and large amount of measured data of typhoon“Meranti”is achieved.By analyzing the data deeply,the variation law of wind direction and fluctuation characteristics of typhoon“Meranti”is given.
