用于三相并网逆变器稳定性分析的自导纳和伴随导纳建模
Self and Accompanying Admittance Model for Three-phase Grid-tied Inverter Stability Analysis
摘要
Abstract
The admittance (or impedance)-based approach is commonly used in stability analysis of the grid-inverter system.The paper illustrated the single-frequency input double-frequency output (SIDO) phenomenon and mechanism in a three-phase grid-tied inverter based on phase locked loop (PLL) control,which was distinct from the sequence coupling in impedance model reported recently.Then the complex variable representation was used to build admittance models,making the positive and negative sequence admittances lumped into one unity admittance.Moreover,Nyquist criterion analyzed the self-admittance and accompanying admittance effects on system stability.Simulation and experimental results verified the stability analysis results are more accurate by using the proposed admittance models in stationary frame.关键词
