摘　　要：为满足国际海事组织MARPOL尾气排放要求,远洋船舶开始加装废气洗涤系统。因该系统含有大功率变频器,电力电子器件,使船上电网的谐波污染不断加重。文章通过谐波仿真建模计算分析,提出了有源电力滤波器的使用方法。文章分别对加装滤波器前后电网中的谐波含量进行对比分析研究,发现加装滤波器后,谐波含量显著下降,达到了对船上谐波治理的目的,效果比较理想。In order to meet the emission requirements of articles 14.1 and 14.4 of Annex VI of MARPOL of the international maritime organization,more and more ocean going ships begin to install waste gas washing systems,which can effectively remove the sulfur oxide emissions from the tail gas.The waste gas washing system adopts a high-power seawater pump,which is matched with a high-power frequency converter to adjust the washing water flow in real time.With the application of high-power electronic devices,the harmonic pollution of ship power grid is increasing,which has an impact on the safe and stable operation of power grid.How to control the harmonic of power grid to reduce the impact of harmonic on shipboard power load is particularly important.This paper analyzes the application of active power filter in ship technical transformation through harmonic simulation modeling and calculation.
