摘要

本文介绍了一种用于光伏发电系统与公用电网互联的功率调节单元(PCU)的设计。该PCU采用六脉冲三相逆变器和修正正弦脉宽调制(MSPWM)开关技术、并联和串联滤波器以及直流到交流功率转换的有效控制。并联和串联滤波器的设计既能降低谐波，又能校正功率因数。直流到交流功率转换的有效控制使逆变器输出电压不受直流电压变化的影响。本文对所提出的PCU进行了方程求解和广泛的仿真研究。设计了一种5mw的PCU，并对其性能进行了详细的研究。

Low-Harmonics Three-Phase Power Conditioner for hotovoltaic Integration

This paper describes the design of a power conditioning unit (PCU) for photovoltaic power system to be interconnected with the utility grid (UG). The proposed PCU employs six-pulse three-phase inverter with modified-sinusoidal-pulse- width-modulation (MSPWM) switching technique, a parallel and series filters and an efficient control of dc to ac power conversion. The parallel and series filters are de- signed for both harmonics reduction and power factor correction. The efficient control of dc to ac power conversion makes the inverter output voltage immune to the variation in the dc voltage. The proposed PCU has been studied with both equation solving and extensive simulations. A 5 MW PCU has been designed and its performance has been investigated in detail.
