Reaserch on Simulation of a Novel Single-Phase H5 Photovoltaic Grid-Connected Inverter Based on PR Controller
摘要
Abstract
In order to improve the utilization of new energy sources,this paper proposed a new type of single-phase inverter based on H5 topology,while for the problem of poor performance of non-fundamental frequency interference about PR control on the H5 inverter,the PR(proportional resonance) controller was improved to QPR(quasi-resonant proportional) controller to overcome the grid frequency fluctuation sensitive defects of the PR control.A single-phase PV system simulation model with H5 topology in Simulink platform was built to verify the theoretical analysis and results,which show QPR can not only realize static error tracking,but also have excellent resistance to grid disturbance,and achieve a unity power factor.Finally,the simulation results verify the accuracy and feasibility of the improved control strategy,which has positive significance for improving the performance of small power inverter.关键词
