本文提出了具有电能质量改善能力的分布式发电系统的物理模型。该发电系统由一个5kW的PEM燃料电池、一个天然气重整器、储氢瓶和一组超级电容器组成。附加的电能质量功能是通过一个矢量控制的电子转换器实现的，用于调节注入功率。该系统的性能在一个规模的电网上进行了实验测试。它由不同的线路组成，由线性电感和电阻组成，并考虑线性和非线性负载。通过对物理模型电网产生不同电压和频率的扰动，测试了改进电能质量的能力。
In this paper, a physical model for a distributed generation (DG) system with power quality improvement capability is presented. The generating system consists of a 5kW PEM fuel cell, a natural gas reformer, hydrogen storage bottles and a bank of ultra-capacitors. Additional power quality functions are implemented with a vector-controlled electronic converter for regulating the injected power. The capabilities of the system were experimentally tested on a scaled electrical network. It is composed of different lines, built with linear inductances and resistances, and taking into account both linear and non-linear loads. The ability to improve power quality was tested by means of different voltage and frequency perturbations produced on the physical model electrical network.
