| Abstract: |
| Because of low temperature and high humidity in high altitudes wind farms in south China, the wind turbine generators were affected by freezing frequently and heavily, which causes total power generation losing and even safety problems. According to these reasons, anti-freezing design of wind turbine generator was proposed. The passive coating technique and the active heating technique were introduced in blade design; ultrasonic anemometer was chosen in wind turbine; the nacelle and the cover of hub were designed in streamlined; and the anti-freezing control strategy was added in the master control program. These designs were tested in a Yunnan wind farm. The result showed that the freezing problem was solved successfully; the total power generation is significantly higher than the other units. The purpose was to provide reference for anti-freezing design of wind turbine generator. |
