| description | A ship variable-frequency load motor-capacitor inertia frequency modulation cooperative control method comprises the following steps: establishing a system power-frequency state equation and carrying out discretization processing to generate a system prediction model, and further setting a cost function which comprehensively reflects system performance requirements of suppression frequency fluctuation and load control. The control problem of the variable-frequency load is converted into a constraint optimization model, the optimal voltage and rotating speed adjustment amount are solved through a model prediction control method, the result is applied to a ship load frequency converter in a feedback control mode, and the effect that the variable-frequency load participates in frequency adjustment in a self-adaptive mode is achieved. Inertial stored energy is released by actively adjusting voltage-rotating speed, so that the load participates in adjustment; compared with a single capacitor/rotor energy storage f |
