摘要

[Objective]The study aimed to assess the risk of tropical cyclones to wind farm operation in northern costal areas of Jiangsu Province.[Method]Based on tropical cyclone data during 1951-2011 from nine national basic weather stations as well as wind data during 2005-2007 determined by six gradient wind measurement towers in northern costal areas of Jiangsu Province,the spatial and temporal distribution of tropical cyclones influencing northern coastal areas of Jiangsu Province were discussed firstly,and then the possible effects of tropical cyclones on wind farms in the northern costal areas were assessed,finally some suggestions about type selection and parameter design of wind turbines were proposed.[Result]Annual average number of tropical cyclones influencing northern coastal areas of Jiangsu Province was 1.7,and the first two kinds of tropical cyclones were dominant in quantity,accounting for about 73%for total quantity.The quantity of tropical cyclones bringing substantial economic benefits to wind farms accounted for 87.7%of total quantity,with annual average quantity of 1.5.Maximum wind speed appearing every 50 years did not exceed 37.5 m/s,in accord with the national Grade-III standard for safe operation of wind turbines.2.1%-3.8%of turbulence intensity eigenvalues at a height of 70 m exceeded the maximum anti-turbulence intensity designed by IEC(0.16),and it is suggested that anti-turbulence intensity parameter of wind turbines in northern costal areas of East China should be changed to 0.31-0.41.[Conclusion]The research could provide scientific references for design and choice of wind turbines as well as operation and management of wind farms in the study region in future.
