摘要：近年来，随着国家海洋战略的实施，船海技术等领域有了突飞猛进的发展，在船用电源的选择、大功率负载、船用变频器上广泛采用了非线性的电力电子装置，造成了大量的谐波污染，已经无法再维持船舶电网的正常供电。因此，就如何解决这种谐波污染，成为了当今电力系统发展的首要目标。而并联型有源电力滤波器在性能上具有响应的速度快和易于控制等特点，对谐波有很好的滤除效果，且对优化电能质量有着不可或缺的作用。本文主要介绍三相三线制并联型有源电力滤波器，从以下几个方面展开了分析：

本文首先介绍了谐波的基本概念以及在船舶电力系统中的产生原因和对于系统的严重危害，并对谐波抑制的相关方法和并联型有源电力滤波器在目前的研究情况，进行一定的阐述。其次研究了基于d-q变换的相关原理，在这种基波与谐波分离上又采用了Butterworth滤波器。建立三相三线制的主电路模型，在控制电路的选择上，本文主要研究了滞环比较法，建立出滤波器主电路的数学模型，并在各参数的选择上进行相关的运算。依据瞬时电流跟踪控制原理，估算负载侧电感的取值。在直流侧电压的稳压设计上，采用了PI调节器，以闭环控制为基础进行仿真和建模，设计相关的调节器的参数。最后在Matlab/simulink中电力系统模块中对并联型有源电力滤波器进行了实验仿真研究，验证了各个模块的功能。仿真结果表明，该方案能很好的抑制谐波。

Abstract：In recent years, with the implementation of the national marine strategy, ship and sea technology and other fields have developed by leaps and bounds in the choice of marine power supply, high power load, marine frequency converter widely used non-linear power electronic devices, resulting in a large number of Harmonic pollution, has been unable to maintain the normal power supply of the ship's power grid. Therefore, how to solve this harmonic pollution, has become the primary goal of today's power system development. The parallel type active power filter has the characteristics of fast response and easy control in performance, has good filtering effect on the harmonics, and has an indispensable role in optimizing the power quality. This paper mainly introduces three-phase three-wire parallel active power filter, from the following aspects of the analysis:

This paper first introduces the basic concept of harmonics and the causes of the ship power system and the serious harm to the system, a certain Elaborated. Secondly, the correlation principle based on d-q transform is studied, and the Butterworth filter is used in this fundamental and harmonic separation. In this paper, we study the hysteresis comparison method, establish the mathematical model of the main circuit of the filter, and carry out the related operation on the selection of the parameters. In this paper, we study the main circuit model of the three-phase three-wire system. According to the instantaneous current tracking control principle, estimate the value of the load side of the inductor. In the DC side of the voltage regulator design, the use of PI regulator, closed-loop control based on simulation and modeling, design of the relevant parameters of the regulator. Finally, the simulation of the parallel active power filter in the power system module of Matlab / simulink is carried out to verify the function of each module. The simulation results show that the scheme can suppress the harmonics well.
