摘要:

近年来，配电网的电能质量问题日益突出，有源电力滤波器(APF)由于其突出优点成为解决该问题的主要技术手段之一。首先建立基于单相VSI的中性线APF的Euler-Lagrange(EL)系统模型，在此基础上对系统进行无源性设计，获得相应的电流跟踪控制策略，并基于FPGA设计了一块控制板。最后，仿真及对10 kVA中性线有源滤波器的实验结果证明了上述显著特性。

Abstract:

In recent years, there are many power quality problems in the distribution system, and active power filter(APF) becomes one of the main technique. This paper first establishes the Euler-Lagrange(EL) model of the neutral APF based on single-phase VSI, which the passivity design is based on. Then the control scheme tracking the desired current is derived accordingly and a PCB board is designed to carry out the algorithms based on FPGA. The simulation and experiment result shows the validity of the design in the end.

Key words: Euler-lagrange modeling damping injecting passivity neutral APF FPGA
