Variable Ratio Hydrostatic Transmission Simulator for Optimal Wind Power Drivetrains

الملخص EN

This work presents a hydromechanical transmission coupled to an electric AC motor and DC generator to simulate a wind power turbine drive train.

The goal of this project was to demonstrate and simulate the ability of a hydrostatic variable ratio system to produce constant electric power at varying wind speeds.

The experimental results show that the system can maintain a constant voltage when a 40% variation in input speed is produced.

An accompanying computer simulation of the system was built and experimentally validated showing a discrete error no larger than 12%.

Both the simulation and the experimental results show that the electrical power output can be regulated further if an energy storage device is used to absorb voltage spikes produced by abrupt changes in wind speed or wind direction.
