摘要

本文介绍了一种工作在孤岛模式下的单相逆变器的控制设计。该控制旨在提高暂态响应和抗扰性。控制器的结构是一个比例积分加上一个比例。在比例-积分回路中加入一个重复控制器,在比例回路中加入一个posicast控制器。在逆变器中设置暂态控制器的目的是改善对负载阶跃的暂态响应。得到的瞬态响应是低响应阻尼,振荡少,透支21%。该重复控制器具有提高抗扰性的功能,在非线性负载下实现电压总谐波畸变为2.64%,并保持了电压信号的幅值、频率和波形。

Design ofthe Control of a Single-Phase Inverter in Island Mode to Improve both the Transient Response and the Disturbances Rejection in a Microgrid
In this paper, the control design of a single-phase inverter working in island mode is presented. This control aims to improve both the transient response and the disturbances rejection. The structure ofthe controller is a proportional-integral plus a proportional. In the proportional-integra loop a repetitive controller is added and in the proportional loop a posicast controller is added. The purpose of the posicast controller in the inverter is to improve the transient response to load steps. The transient response that is obtained is a low response damped with few oscillations and an overdraft of 21%. The repetitive controller has the function of improving the disturbances rejection, achieving a total harmonic distortion ofvoltage to 2.64% with non- Iinear loads and maintaining the amplitude, frequency and waveform of the voltage signal.
