Research on control strategy of single-phase photovoltaic grid-connected inverter based on H6 bridge
摘要
Abstract
The single-phase H6 inverter has the ability to suppress the leakage current,In order to make photovoltaic grid-connected power generation system to export high quality power.On the basis of H6 bridge inverter,It presents a PI +QPR complex control strategies which not only overcomes the disadvantages of QPR (Quasi Proportional Resonance) control for low frequency DC component suppression,but also solves the problem of PI control in the presence of steady state error;Based on Simulink,the simulation model was established.The results show that the new control strategy can not only achieve the static error free tracking,and effectively reduces the frequency DC component,but also can achieve unity power factor.The accuracy and feasibility of the proposed control strategy are finally verified,In practical application,it has great engineering value.关键词
