摘要:In the process of Biomedicine PV Grid, in order not to affect the quality of the grid, must ensure that the output current of photovoltaic power generation system and grid voltage maintain a high degree of consistency in the frequency, phase and amplitude. In order to make the output current of PV Grid inverter to meet the relevant standard of the grid, the appropriate grid filter and control strategy is the key. In order to improve the quality of the grid current and reduce the pollution of the grid harmonic current on the grid, select the three-phase full-bridge inverter circuit with LCL filters. In the grid control strategy, select the double loop current control based on grid current and capacitance current, and introduce the PR control into the double loop control system, analyze that PR control can achieve zero steady state error tracking of grid sinusoidal reference current and anti-grid voltage disturbances. Make double loop current control and SVPWM control combined, and prove the stability of this method through the simulation experiment.
