摘要

并网变流器在新能源发电、电能质量治理等领域的应用逐渐广泛，但其输出的并网电流谐波对电力系统有很大影响。重复控制是通过在参考波形中引入谐波成分，并在控制器中将其与误差信号进行比较从而抑制谐波的一种方法，因其对周期性扰动有良好的跟踪性能而在并网变流器中得到广泛应用。但当电网频率波动时，重复控制的谐振频率将会偏离实际电网的基波和谐波频率，大大降低了并网变流器的谐波抑制能力。对此文中提出一种与PI复合应用的多内模自适应重复控制策略来抑制并网变流器中的谐波干扰。首先给出所采用的典型并网变流器拓扑及其控制结构，建立其数学模型；其次针对传统重复控制器的缺点，引入校正因子以增强谐波下的控制增益，提升系统的频率适应性；最后对提出的控制策略进行参数设计，并通过仿真和实验验证了所提策略的有效性。

Abstract

The application of grid connected inverters in new energy generation

power quality control and other fields is gradually widespread

but its output harmonic of the grid connected current has a significant impact on power system. The repetitive control is a method to suppress harmonics by introducing harmonic components into the reference waveform and comparing them with error signals in the controller. It is widely used in grid connected converters due to its good tracking performance to periodic disturbances. However

in case of power grid frequency fluctuation

the reasonant frequency of the repetitive control will deviate from the fundamental and harmonic frequencies of the actual power grid

which greatly reduces the harmonic suppression ability of the system. Therefore

in this paper a multi-internal model adaptive repetitive control strategy combined with PI is proposed to suppress harmonic interference in grid-connected converters. Firstly

the typical topology and control structure of the used grid connected converter are given and its mathematical model is set up. Then

in view of the shortcomings of the traditional repetitive controller

the correction factor are introduced to enhance the control gain under harmonics and improve the frequency adaptability of the system. Finally

parameters of the proposed control strategy are designed

and the effectiveness of the proposed strategy is verified through simulation and experiments.
