Abstract

Solar energy is considered as one of the most consistent green energy in our country with the regular sunny days in Malaysia and the condition of weather here is good throughout the year. Besides, Malaysia does have winds of approximately 10 to 20 knots (approximately 5.14 to 10.29 m/s) of wind speed energy but it is dependent on the monsoon season and sea breeze. Thus both the solar and wind power will be integrate together in the project. In the project, it is important to know how system should works when lack of either source of energy so that losses in integration would be minimize. The problem in integrating is the suitability of connection and how to minimize the losses. Thus the objective of the project is to design and develop a wind energy conversion system for solar VAWT and to integrate wind and solar power as a hybrid system that can function concurrently. To start all the work, review have been made on various sources so that the direction of the project is specified. Then, the work that carried out are the conceptual design that includes the transmission for energy conversion, size and type of generator, solar panel specification in terms of suitability as well as the integration of power with consideration on the local weather condition. Then appropriate material and application are used to fabricate the project prototype so that testing are able to be done. The generator used is the normal dc motor generator, whereas chain drive is used as the energy extraction. Circuit design is done between solar and wind power system with addition of diode to further improve the performance of the system. With the prototype done, testing and analysis through site have been carried out with the result of parallel circuit with blocking diode as the better circuit for this prototype. Site test purpose is also to show that the system are able to work as according to design and targeted location. Through laboratory test, the parallel circuit is further analyse on its characteristic on various controlled environment. The results shows that the system are able to integrate both solar and wind power system at similar power output range and performance is lowered when the power output range varies in large amount. The results is plotted into graph where intersection shows the range at which the performance rate changes. However the power dissipation is still low for solar panel whenever the variation of power output is large. The generator itself also shows that the efficiency grows higher as the rpm. The generator performance have not reached its optimum as well. The testing for integration shows that efficiency of the generator reached maximum at 39.3% at wind speed 4m/s. Thus there’s room of improvement that can be done on the future work.
