Abstract

The invention belongs to the field of pulse power generation, particularly relates to a pulse power supply system based on a generator cluster and an energy storage microgrid and a discharging method,and aims to solve the problem that residual energy of a pulse generator cannot be fully utilized in the prior art. The method comprises the following steps: respectively discharging each pulse generator based on a system discharge signal and parameters; grouping the pulse generators, and transferring the residual energy of each group to any pulse generator in the group; discharging again, grouping the pulse generators with available residual energy, and performing energy transfer again; and iteratively discharging the pulse generator set until the rotating speed of the pulse generator is reduced to the condition that discharge and the power generation indexes do not meet the requirements. According to the invention, by utilizing the characteristic that through the controllable rectification of charging motor, constant-voltage power generation can be carried out in a wide rotating speed range, so residual energy can be transferred in the pulse generator cluster, the conversion ratio from inertia kinetic energy to pulse electric energy is improved from the system level, and the energy utilization rate is improved.

technical field [0001] The invention belongs to the field of pulse power generation, and in particular relates to a pulse power supply system and a discharge method based on generator clusters and energy storage microgrids. Background technique [0002] The pulse generator is a special rotating electrical machine that integrates flywheel energy storage, electromechanical energy conversion and pulse discharge. The discharge energy density of the pulse power supply system based on the pulse generator can reach 2-3 times that of the capacitor, which is conducive to the miniaturization of the pulse power supply. At present, most of the large-scale pulse generators developed at home and abroad have a single inertial energy storage of no more than 50MJ, and most of the single pulse discharge energy does not exceed 4MJ, which cannot meet the demand. Therefore, it is necessary to use multiple sets of pulse generators in parallel. total discharge energy. The pulse power supply syst...
