Hydraulic full-period frequency modulation new energy generator set and primary frequency modulation method thereof

The invention relates to a hydraulic full-period frequency modulation new energy generator set and a primary frequency modulation method thereof. The generator set comprises paddles, a one-way quantitative hydraulic pump, a coupler, a proportional throttle valve, a two-way variable hydraulic motor, an excitation synchronous generator, a grid-connected cabinet, a water turbine, a water valve, a water storage tank, a water pump, a leather bag type energy accumulator, an energy conversion element, a hydraulic oil tank, an overflow valve, a generator, an oil supplementing pump and a one-way valve. According to different wind conditions, the power grid is divided into three areas, namely a maximum power tracking area, a constant rotating speed area and a constant power area, and when the frequency of the power grid deviates from 50 Hz, the stability of the frequency of the power grid is controlled by changing the rotor kinetic energy of blades, the opening degree of a proportional throttle valve, the energy storag
