Ice melting from wind turbine blades using resistive heating

Abstract: The paper is related to removal of the ice accumulated on the wind turbine blade the nichrome coil is embedded in the wind turbine when the wind turbine blade is being manufactured. In the invention a super capacitor is used to give energy to the nichrome coil embedded in the wind turbine blade. The pulses are given after every one minute to the nichrome coil in the season of snowfall. Due to this the turbine blade is heated due to resistance heating. The temperature of the turbine blade is increased. The ice is melted. Even if the lower layer of the ice is melted the remaining ice is slipped below due to gravitational force. For this one revolution of the turbine is made. Precaution us taken that no humans or animals are standing below and in close vicinity of the wind turbine when the turbine is I deicing is being done.

Laboratory model of surface roughness to test wind turbine voltage flicker

Abstract: In this paper the test set up is developed in which there is a provision of various surface roughnesses in the test set ups. In the test set ups there is a provision of sea sand, river sand, river pebbles of various sizes, grass, building models of various heights, hills models of various heights and slopes and offshore environment with artificial water waves is available. The main idea in this patent is that various types of surface roughness are created in the wind turbine test set up. The onshore environment can be created by using trays of sand of various sizes. The offshore environment can be created by using a tray of water at the bottom of the test set up. Artificial waves of water are created by a motor coupled with four longitudinal cups welded together and mounted on a shaft. Because of this continuous waves are produced. Another method of producing waves is that use a surface with inverted V all along the surface. The water is needed to move continuously with the help of a pump. This will also create the waves. The impact of wave height on flicker will be observed. For the surface of grass actual grass tiles may be fixed on the surface of the wind turbine test set up. For river bank surface, sand and pebbles of river can be kept at the bottom of the test set up
