Abstract :
This paper derives the relationship between drag coefficient and electrical power of generator by deducing the connection between drag coefficient and rotor power coefficient. The efficiency losing state of running is introduced to the simulation of aging of blade and control strategy and using variable-pitch control is utilized under the efficiency losing state of running. The simulation result of software Matlab display that wind turbine operates safely by using the strategy under efficiency losing state of running.
