The demand for community wind turbines is increasing to fulfill local requirements and make the grid more stable. A turbine with a hydrostatic transmission is more reliable and cost effective than a conventional gearbox turbine making it an attractive alternative for community wind turbines. A power regenerative test platform has been built at the University of Minnesota to understand the performance of a hydrostatic transmission in a wind turbine. The design of the test bed is described in detail in this paper. The testbed emulates the rotor torque including the effects of the blade dynamics and pitch in a hardware-in-the-loop configuration. This test platform provides a powerful tool to investigate the performance of new components, controllers, fluids and energy storage methods on the hydrostatic wind turbine transmission.
