Abstract

Aiming at the intelligent control strategy of the hot air blower de-icing technique for wind turbine blades was requirement. A high efficient and energy-economical intelligent control strategy was designed, the control strategy workflow and two intelligent modes were designed, namely pre-heating mode and de-icing mode. Through field de-icing tests, the results showed that the inner temperature of blade tip was around 30 when running at pre-heating mode, the blade tip surface temperature was 5 , which was able to restrain ice formation and supply fundamental heat for de-icing mode. The inner temperature of cavity reached 60 for supplying enough heat to de-ice quickly when running at de-icing mode. Compared with the conventional de-icing method, the intelligent de-icing control strategy was saved 80% energy consumption in one icing period, which improved electrical production. The feasibility of the intelligent control strategy was proved and it benefited for further development of wind turbine industry under cold weather conditions.
