摘　　要：为了提升电网抵御台风灾害的能力,从运行角度出发提出一种电网台风风险预警方法。根据气象局提供的台风预测信息,通过比较线路网格到台风中心的距离s与台风十级风圈大小,确定危险线路集,并计算危险线路集中线路的预测风速vy,再由预警区域内线路的基础信息校正线路设计风速后作为判断风速vp,比较预测风速与判断风速的大小,得到预警结果,并发布相应预警信息。同时,考虑到人工设置的门槛值主观性强,设计了一种自动校正方法,提高了预警的准确性和系统的可移植性。通过中山电网实际运行测试,验证了所提方法的有效性。In order to enhance the ability of power grid to withstand typhoon disaster, an early warning method for power transmission risk of typhoon is proposed in this paper from the perspective of operation. According to the typhoon forecast information provided by the meteorological administration, the risk set of line is determined by comparing the distance from grid center to typhoon center with the wind radius of level ten,and the corresponding forecasting wind speed is calculated, then the warning results is got through comparing calculated wind speed with judge wind speed which is corrected on the design wind speed of transmission line by basic information recorded in the early warning area, and appropriate warning information will be released in time. Moreover,an automatic correction method for the system is designed to improve accuracy of the early warning and portability of the system, as the subjectivity of warning threshold value set by people is strong. The real operation test of Zhongshan power grid is taken to verify the validity of the proposed method, and the result shows that the typhoon risk early warning method is effective.
