基于模态分析的多逆变器系统串并联谐振特性分析
Series-parallel Resonance Analysis of Multi-inverter System Based on Modal Analysis
摘要
Abstract
The resonance analysis method based on modal analysis can obtain accurate resonance positioning of a multi-inverter system,but it has shortcomings in the identification of resonance types.In this paper,a resonance identification method based on modal analysis and participation factor calculation is proposed for multi-inverter systems.A Norton equivalent model of the inverter with active damping of the capacitance current is established and the line impedance is considered.The result difference between series and parallel resonance modal analysis is analyzed when the inverter combination changes.The characteristics of different types of resonances are obtained by classifying the resonance types.A specific modal analysis method is selected for each type of resonance,and the type of resonance is identified by the performance of the participation factor.Finally,a simulation circuit model and an experimental platform are built to verify the correctness of the conclusions.关键词
