Efficiency analysis and controller design of a continuous variable planetary transmission for a CAES wind energy system
چکیده انگلیسی

This study proposes a CAES wind energy storage system composed of a windmill, a continuous variable planetary (CVP) transmission, a flywheel, a clutch, a reciprocating compressor, and an air tank. The mode of transformation of wind energy into compressed air in the system is also illustrated, in addition to details on the process of the controller design. The system controller can adjust the gear ratio according to the wind speed (Vwind) and rotational speed of the flywheel (ωflywheel). With a proper controller design to control the gear ratio, the flywheel can rapidly reach a rotational speed that is suitable for compressing the air into a tank. In addition, the windmill can be operated at the most efficient point. Therefore, transformation efficiency of wind energy into compressed air could be improved. After completion of the controller design, the efficiency of the two air compression systems (one system is driven directly by the windmill and another is driven by the flywheel) are compared to determining the target for improving performance in the future.


► CAES wind energy system expands the operable range for wind generator system.
► The controller makes the windmill work at its optimal efficiency.
► The energy transforming process excludes electrical transforming process.
