In this paper deicing mechanism for wind turbine is developed. Hot water is used to remove the ice accumulated on the wind turbine blades. The pipes are embedded in the wind turbine blades. The pipes which are embedded may be made up of copper or steel or any other thermally conducting material. The water pipe is connected to the blade from the water tank placed at the ground. The water is heated by water heater. The water heater may be an electric heater. The water may also be heated by gas geyser. The water pump is used to circulate the water from the water tank to the wind turbine blades. When the water pump is started it circulates the water through the water heater and the wind turbine blades. The pump keeps the water circulating through the wind turbine blade until the ice melts and falls down. In the environmental conditions favorable for ice accretion on the wind turbine blades, the pump circulates water through wind turbine blade after frequent intervals of time to prevent ice accretion on the wind turbine blades. © 2017 IEEE.
