Windflow’s synchronous power-train

A torque-limiting gearbox/low variable-speed system for wind turbines

Identification

Windflow’s power-train and its synchronous generator enable wind turbines to provide physical inertia and system strength for grid stability.

Windflow's solution is a mechanical Variable Speed (VS) system called the torque-limiting gearbox/low variable-speed (TLG/LVS) system which leaves the generator speed constant (set by the grid) and has a differential (a planetary stage with one input from the wind turbine and two outputs) in the gearbox. One output from the differential drives the generator (constant speed), the other drives a hydraulic pump (variable speed). A hydraulic circuit controls the torque, while the turbine speed is controlled by pitching the blades. Together the hydraulic circuit and the blade-pitch control the power on the generator shaft, enabling it to be synchronous. Thus the important stability benefits of the synchronous generator can be retained while renewable penetration increases.
