In this project wind turbine system will be constructed to generate power to supply electricity for buildings demands and batteries . In the first part of the project blades of the wind turbine will be designed and manufactured based on the specific of the wind generator. In the second parte of the project the wind turbine will be installed on roof of scientific centers building and then the wind turbine will be connected by wire into control unite in the energy research center (ERC) , the control unit will be connected with batteries and inverter . The third part of the project data of the wind speed will be measured by using anemometer , at the same time the value of current and voltage will appear on the computer screen which interface with PIC , then the data obtained will be tabulated and analyzed. According to results, The average of wind speed in the site have a value of 6 m\s and the maximum out put power generated from wind turbine was at this speed equals 170 W, the annual energy obtained from wind turbine equals1489.2 kwh the wind turbine life is about 20 years So, the average energy obtained from wind turbine during life cycle of turbine is about 29784 kwh , the total cost of wind turbine system was $ 6750 during life cycle after calculation the cost of one kwh is $0.226 = 0.85 NIS. The system combined with the controlling system (Whisper Controller) having the basic functions which are, rectification, regulation, and resistive power dumping. The output current from controller was DC current , the controller was connected with PIC that include ( current sensor , voltage sensor ) the PIC interfaced with wind sensor and connected in the computer to show the data on computer screen , the system also connected with inverter to invert the current from DC to AC , the final part of the system was batteries that storing the additional electricity . In the final part of the project , the availability of using such a system in other area in Palestine will be discussed taking into consideration ,environmental , and other concern .
