Abstract
To address the practical issues of severe harmonic pollution,three-phase current imbalance and frequent power supply fluctuations in the power grids of high-altitude pastoral areas in China,this paper designs a multifunctional bidirectional inverter integrating the functions of a three-phase voltage-type PWM rectifier,a grid-connected inverter and an active power filter.The system supports two operating modes which are energy storage rectification and harmonic compensation.In rectification mode,it modulates the three-phase half-bridge structure through SPWM to achieve stable charging of the DC-side energy storage unit while providing active filtering capability.In filtering mode,the system disconnects the energy storage side interface and adopts an ip-iq harmonic extraction strategy based on the improved Clark transformation and DSOGI algorithm.It combines SRF-PLL phase-locked loop to realize high-precision detection and real-time compensation of grid harmonic and unbalanced currents.The system exhibits good robustness,harmonic suppression capability and dynamic tracking performance in the complex high-altitude environment.It provides strong support for the integration of distributed power sources and power quality optimization in high-altitude areas.关键词
