What should the wind farm do when it encounters extreme rain and snow?

1, during the rainstorm, electrical and turbine professionals should immediately draw out personnel to enter the site to ensure that the sewage pumps in the circulating water pump house, condensate pump pit and condenser pit are in good condition and ensure normal operation.

2. In winter, the wind farm freezes seriously. When the blade freezes, the aerodynamic characteristics of the blade become worse, the lift coefficient decreases, the drag coefficient increases, and the blade will enter a stall state. When starting the machine after melting ice, the power should also be increased slowly, and the operation of each part of the unit without preheating is not conducive to the safe and stable operation of the unit.

3. The temperature is close to 0℃ and the air humidity is above 80%. According to experience, the blades of the unit will freeze. The operator observed that the wind speed did not match the output of the unit obviously, and the output quickly dropped below 30% of the standard power of the corresponding wind speed. Stop the machine immediately to ensure the safety of the fan.
