Abstract

This paper analyzes the stability of a grid-following inverter by the complex vector control in αβ domain and by the PLL synchronization control in dq domain. It is known that the frequency transfer function of the PLL may affect mutual interactions between grid and line impedances. This paper analyzes the frequency characteristics of the inverter based on the mixed-domain control for stability by the impedance method. Considering frequency coupling effects by the PLL control, it is found that the passivity of the inverter is violated and it may become unstable for a weak grid. This result is validated by analytical derivation, simulation, and experiment.

考虑锁相环效应的复杂矢量控制电网跟随逆变器稳定性分析

本文在αβ域采用复矢量控制，在dq域采用锁相环同步控制，分析了电网跟踪逆变器的稳定性。我们知道锁相环的频率传递函数会影响栅极和线路阻抗之间的相互作用。本文用阻抗法分析了基于混合域稳定控制的逆变器的频率特性。考虑到锁相环控制的频率耦合效应，发现逆变器的无源性被破坏，在弱电网中可能变得不稳定。通过解析推导、仿真和实验验证了这一结果。
