Abstract

In this paper a grid-connected PV system is presented. Its main feature is that, besides injecting energy into the grid, it behaves as an active filter. The reference signal used to modulate the output current is obtained through an adaptive filter. The main advantages of the technique are that the system becomes almost independent of the parameter variations, and that it lends itself to a very simple hardware implementation. A 1 kW prototype was built and tested. The results obtained show good compensation of the current drawn by nonlinear loads.
具有功率因数校正能力的并网光伏系统
本文提出了一种并网光伏发电系统。它的主要特点是,除了向电网注入能量外,它还表现得像一个有源滤波器。用于调制输出电流的参考信号通过自适应滤波器获得。该技术的主要优点是系统几乎不受参数变化的影响,并且它使自己成为一个非常简单的硬件实现。建造并测试了一台1千瓦的原型机。结果表明,该方法对非线性负载产生的电流具有较好的补偿作用。
