The Experimental Study On Streetlight 50W Wind Turbine

The project stems from Hengshui "50W lamps wind turbine research".Designed 11 impllers of 50W to match the generator and make a contrast of power output characteristic by lorry experiment . By comparing a variety of wind turbine start-up and power output characteristics,we can make sure a small start-up wind speed, good power output of wind turbine.We designed 11 sets of wind turbines of 50W matching with 50W wind turbine generator①Three sets of lift- type vertical axis wind turbines, adding good start-up resistance-type blades on arms;②Four sets wind turbines of concentrated wind energy turbine by using the theory and methods of concentrated wind energy turbine③With the premise of the same diameter, designed four sets of propeller-type wind turbines in accordance with BEM.The experimental results show that:①compared to output power between propeller-type blades and amendment–type blades , with the same speed and the same number of blades ,the output power for the largest difference is 5.39W which indicates the principle of amending is feasible.②we can get the conclusion to contrast start-up wind speed and output power between all of the impellers,the wind turbine with six-blades in the chord length 1.25 times of designed chord has a best start-up wind speed and reach the rated power with a lower wind speed ,especailly higher output power in lower wind speed and good stall performance in high speed . This wind turbine is suitable to 50W lamps generators.
