摘要

本文研究并实现了一种基于Zeta变换器的模块集成逆变器的最大功率点跟踪技术。集成模块的逆变器允许PV太阳能电池板产生的电力注入商业电网。这种结构比采用多个面板连接到大型单个逆变器(中央逆变器)的结构具有显著的优势。模块集成结构提供的优势可以突出:模块化,允许系统的自然并行性,增加了系统的可靠性,因为在模块故障的情况下,工厂在所有能量由几个光伏板及其独立工作的模块集成逆变器提供后仍保持供电,最后,有可能单独获得MPPT,这在大型系统中非常有趣,因为只有几个面板可能发生遮阳。这项工作中采用的系统包括将PV阵列与Zeta转换器级联,并与以相同频率与电网同步运行的单相全桥逆变器相关联。在DCM中工作的Zeta变换器负责合成与电网同步的整流正弦电流波形。CSI用于每180°反转一次电流。本研究考察了三种MPPT技术,即恒压、摄动、观察和爬坡。使用数字信号处理建立了一个原型。得到的结果验证了所提出的研究,在工作中描述。

MPPT techniques applied to the control of a module-integrated inverter grid-connected based on Zeta converter for PV panels
This paper presents the study and implementation of maximum power point tracking techniques (MPPT) applied to a module-integrated inverter based on a Zeta converter. The module-integrated inverter allows electricity generated by a PV solar panel to be injected into the commercial power grid. This structure provides significant advantages over the structure that employs the combination of multiple panels connected to a large single inverter (central inverter). Among the advantages offered by the module-integrated structure can be highlighted: modularity, allowing the natural parallelism of the systems, increased system reliability, because in case of failure of a module the plant remains powered after all energy is provided by several PV panels and their module-integrated inverters that work independently, and finally, there is the possibility of obtaining the MPPT individually, which is quite interesting in large systems, where shading may occur in only a few panels. The system employed in this work consists in the association of a PV array to a Zeta converter in cascaded with a single phase full-bridge inverter operating synchronized with the power grid at the same frequency. A Zeta converter working in DCM is responsible for the synthesis of a rectified sinusoidal current waveform synchronized with the grid. The CSI is used to invert the current every 180°. In this study three MPPT techniques were examined, namely Constant Voltage, Perturb and Observe and Hill Climbing. A prototype was built using digital signal processing. The obtained results validated the presented study, described in the work.
