Study on parallel operation of inverters based on droop method

YANG Shu-ying,ZHANG Xing,ZHANG Chong-wei(School of Elec.Eng.and Automation,Hefei University of Technology,Hefei 230009,China)  
This paper analyses the basic principles of droop method for wireless parallel operation of inverters.By adopting some new technologies,the performance of parallel operation system is improved.And in this paper the single inverters based on multiple feedback loop control method and their parallel operation system are designed.To overcome the disadvantages of first order inertial element,which is adopted in traditional parallel operation system to filter the power triples,the second order oscillational element is adopted in this paper,which improves the controllability and performance of the system.And the virtual impedance,adopted in this paper,reduces the impact of the output impedance of the inverters on the performance of parallel operation system.At last,to validate this control method,a prototype is built,which is composed of two 1kVA single-phase PWM inverters based on DSP TMS320F2407A.The static and dynamic performances of the system are tested,and the results show the good performance of the system.
