| Abstract: |
| The work aims to realize the lightweight design of typhoon wind turbine tower. The typhoon environment load cases and the typhoon control strategy were researched. Based on the typhoon wind turbine according to GB/T 31519—2015 Wind Turbine Generator System under Typhoon Condition Standard, the typhoon control strategy was developed to keep the wind turbine in the opposite state during the typhoon. The loads on key parts of the wind turbine unit were calculated by software BLADED and the results indicated that the tower base load was reduced by 23.5% with typhoon control strategy. The tower was redesigned and the weight of tower was reduced by 15%, realizing the lightweight design, saving about RMB 4.16 million for one wind farm and having good economic benefit.According to the field measurement of the wind turbine unit, during the period of typhoon Capricorn, the correlation between the theoretical simulation value of the tower base load Mxy of the typhoon type wind turbine unit adopting the typhoon control strategy and the measured value was 94.1%, which was highly consistent. It verifies the accuracy of the theoretical simulation calculation and the feasibility of the application of the lightweight tower, and contributes to the development of the wind turbine units in the coastal areas and offshore areas of China's wind power industry. |
