摘要

本文介绍了光伏发电微电网接入公共电网时的现象。设计了一种用于微电网供电的光伏逆变器系统，并利用Matlab-Simulink进行了仿真。对三种不同的功率因数进行了模拟，以这种方式显示功率因数如何影响系统的行为，特别是当瞬态发生时。采用PI控制策略对光伏逆变器系统进行控制。该逆变器采用单极电压开关技术的PWM驱动。

Connecting a PV supplied micro-grid to the public grid

In this paper, the phenomena that occurs when connecting a PV energized micro-grid to the public grid, is presented. A PV inverter system, for supplying the micro-grid, was designed and simulated using Matlab-Simulink. The simulations are done for three different power factors, showing in this way how the power factor can influence the behavior of the system, especially when the transitory regime occurs. A PI control strategy is used for controlling the PV inverter system. The PV inverter is driven by a PWM with unipolar voltage switching technique.
