Abstract
The purpose of this research is to determine the efficiency of the “Pneumatic Wind Energy System”, which was invented by Dein SHAW and other people, under various conditions and design a control system. The system is able to control the gear ratio of CVT and the switch of clutch according to the environmental wind speed and the situation of the whole system. And to solve the problem of gas leakage, which happened when air compressor operating under high pressure, proposing an idea of hydraulic subsystem to improve the efficiency of the whole system. The thesis starts from introducing subsystems of the “Pneumatic Wind Energy System” and the way of measuring efficiency. Then explain the logic and operation principle of the control system. Finally introduce the new hydraulic subsystem and its operation principle.
