摘要

本文采用基于阻抗的方法研究了三相并网光伏逆变器系统的稳定性。建立了考虑不同控制回路和无源元件的阻抗模型。建立并比较了同步帧和静止帧中具有电流控制的IMs。讨论了不同控制回路、滤波器参数、工作点以及系统中逆变器数量的影响。可以通过即时消息识别不稳定的原因。

Stability Investigation of Three-Phase Grid-Tied PV Inverters with Impedance-Based Method

This paper presents stability investigations of three-phase grid-tied photovoltaic inverter systems using the impedance-based method. Impedance models (IMs) are established considering different control loops, and passive elements. IMs with a current control in both synchronous and stationary frames are established and compared. Impacts of different control loops, filter parameters, operation point as well as the number of inverters in the system are discussed. It is possible to identify the reason of an instability with the IMs.
