Research on Characteristics of Coastal Wind Power under Typhoon Environment in Fujian Province

The typhoons that landed or affected Fujian province from 2016 to 2018 are statistically analyzed. The results show that in recent four years, there are two typhoons affecting Fujian province every year on average, and seven typhoons landed and five are super typhoon. Typhoon landing in Taiwan island has a great impact on the coastal wind speed of Fujian province. The wind speed firstly increased and then decreased after entering the Taiwan Strait, and increased again before landing in Fujian province. When the typhoon directly landed, the wind speed continued to increase before landing and decreased after landing. The wind farm responded to the possible impact of the typhoon during the high wind speed, and selectively shut down. When the wind speed exceeded the rated wind speed, the wind turbine automatically cut out. When the wind turbine was not shut down or cut out, the consistency between wind power output and wind speed was relatively high. Before the typhoon landed, the output gradually increased to full power, with the intensity of the typhoon weakening, the output of wind power decreased.
