摘要
随着电力传动技术、自动化控制技术的不断发展,现代船舶电力系统中大功率变流装置的应用越来越多,使得船舶电网中的谐波污染日益严重,若不进行有效治理,则会严重影响船舶电网的供电品质和船舶电气设备的安全运行。针对这一问题,论文采用基于模糊PID的有源电力滤波智能谐波抑制方法,并对传统有源电力滤波PID控制中谐波检测中存在的缺陷进行了改进,提高了谐波检测的准确性和实时性。通过仿真实验,对改进前后的谐波抑制进行了验证,结果表明,基于模糊PID控制的有源电力滤波具有较好的谐波抑制效果。
With the continuous development of electric drive technology and automatic control technology,the application of high-power converter in modern ship power system is more and more,which makes the harmonic pollution in ship power grid in⁃creasingly serious.If not effectively treated,it will seriously affect the power supply quality of ship power grid and the safe operation of ship electrical equipment.To solve this problem,this paper adopts the intelligent harmonic suppression method of active power fil⁃ter based on fuzzy PID,and improves the defects of harmonic detection in traditional PID control of active power filter,which im⁃proves the accuracy and real-time of harmonic detection.The results show that the active power filter based on fuzzy PID control has better harmonic suppression effect.
