charger (pile): since many rectification links are used inside the charger, that is, a large number of three-phase rectifier devices are used in the charger, which is a high-power power electronic nonlinear load for the power grid and will generate a large number of harmonics. the existence of harmonics causes serious distortion of the voltage and current waveforms in the charging station power system, greatly deteriorating the power supply quality.
after the active filtering solution is put into use, it can not only ensure that the harmonic current of the distribution system drops significantly, but also improve the power factor of the site. when the capacity is sufficient, the current distortion rate of the site will be reduced from 23% to 5 about %, and can also have both SVG function, both inductive reactive power and capacitive reactive power can be compensated. after compensation and filtering, the power quality is significantly improved.
