摘要

本文介绍了一种多驱动太阳能泵系统。该系统基于单级光伏(PV)拓扑结构，其中太阳能电池板阵列连接到各种逆变器，每个逆变器提供相应的离心泵。逆变器的工作是为了从光伏系统中提取最大功率。采用标准的间接矢量控制策略来调节每台机器的电流。此外，还提出了一种减小逆变器直流共链电流纹波的调制策略。给出了仿真结果并进行了讨论。

A Multi-drive Solar Pumping System with Reduced DC-link Current Ripple

In this paper, a multiple drive solar-pumping system is presented. The system is based on a single-stage photovoltaic (PV) topology where an array of solar panels is connected to various inverters, with each inverter supplying a corresponding centrifugal pump. The inverters are operated to extract the maximum power available from the PV system. A standard indirect vector control strategy is used to regulate each machine currents. Moreover, a modulation strategy aiming to reduce the ripple of the inverters common DC link current is presented. Simulations results are shown and discussed.
