Modeling of gearless wind power transfer

In this paper, a gearless hydraulic wind energy harvesting and transfer system is mathematically modeled and verified by experimental results. The energy is harvested by a low speed-high torque wind turbine connected to a high displacement hydraulic pump, which is connected to hydraulic motors. The quality of transferred power from the wind turbine to the generator is important to maintaining the systems power balance, and frequency droop control in grid-connected applications, and to ensure that the maximum output power is obtained. The gearless wind power transfer technology may replace the current energy harvesting system to reduce the cost of operation and increase the reliability of wind power generation.
