Abstract:
According to the security class of wind turbine generator systems (WTGS), the ch aracters of tracks, intensity and wind of tropical cyclone〖JP2〗 s (TC), which impacted China coast areas, were analyzed in detail by usin g the TC data from 1961 to 2006 and selecting TC which entered the warning regio n about 3 degrees in latitude from the coastline and impacted China coast. The a nalysis showed that typhoon and severe tropical storm (STS) accounted for 59.5% of the total frequency, super typhoon and severe typhoon accounted for 21.5% of the total frequency. In Zhejiang and its southern coast the 10min average maximum wind speed of TC was over 25m·s-1,and it is less than 25m·s-1 in its northe rn coast. The region, where the 10min average maximum wind speed was over 40m·s-1, is mainly at the Guangdong coast east of the Zhujiang Estuary and southeastern coast of Hainan. The high wind of TC, which landed at Fujian and its northern coast and whose intensity was over typhoon, was usually over 25m·s-1, and the intensity of TC, which landed at the south of Fujian and caused high wind, was over severe tropical storm. The availability of TC high wind is over 80% at the middlesouthern coast of Fujian and Jiangsu coast, and the areas are mainly at the middle coast of Zhejiang, the coast at the borderline of Zhejiang and Fujian Provinces and Guangdong coast east of Zhujiang Estuary, where the TC threatens the safety of wind turbines.
