The disclosure relates to a hydraulic drive train with energy dissipation for electrical generation. The disclosure is particularly adapted to wind-driven embodiments wherein the input power can fluctuate quickly. A hydraulic pump is provided in the nacelle of the windmill and powered by the wind turbine shaft. This hydraulic pump provides high pressure oil to generators, typically at ground level. The generators are protected from high pressure oil spikes by a pressure relief valve. Electric pumps on the ground level provide or supercharge the oil to the hydraulic pump in the nacelle.
