Simulation model of PMSG permanent magnet synchronous generator grid connection/matlab

Simulation model of PMSG permanent magnet synchronous generator grid connection
(1) It mainly includes generator, rectifier, inverter (dual pwm control), power grid, control, display and other parts;
(2) The maximum power tracking mppt of the fan adopts the best tip speed ratio method;
(3) Machine side control (power generation control): speed and current double closed-loop control, PI and flux decoupling are adopted; The modulation strategy adopts SVPWM;
(4) Grid-side control (grid-connected control): adopt voltage and current double closed-loop control, both of which adopt PI; Based on voltage feedforward decoupling (active and reactive decoupling); The modulation strategy adopts SVPWM;
(5) Good dynamic response characteristics. When the torque suddenly changes, the generator output speed is stable and the DC bus voltage is stable;
(6) The grid-connected voltage and current are in phase, and the power factor is close to 1;
(7) Small harmonic distortion of grid-connected current, THD=0.01%
