摘　　要：为保证舰船电力系统谐波电流快速得到有效抑制,提出基于智能优化技术的舰船电力系统谐波抑制方法。通过基于p-q检测的舰船电力系统谐波检测方法,由电力系统瞬时无功功率、瞬时有功功率,计算舰船电力系统谐波电流值后,使用基于模糊PID智能优化的谐波抑制方法,改进遗传算法,以谐波抑制后电流畸变最小化为目标,寻优得到模糊PID控制器的最优控制参数后,根据计算的谐波电流与理想电流之间的差值,以谐波电流补偿的方式,完成舰船电力系统谐波抑制。实验结果验证:本文方法应用后,电流畸变情况明显改变,仅用0.005 s便可完成谐波抑制。In order to ensure the fast and effective suppression of harmonic current in ship power system,a harmonic suppression method based on intelligent optimization technology is proposed.Through the harmonic detection method of ship power system based on p-q detection,after calculating the harmonic current value of ship power system from the instantaneous reactive power and instantaneous active power of the power system,the harmonic suppression method based on fuzzy PID intelligent optimization is used,and the improved genetic algorithm is used to optimize the optimal control parameters of fuzzy PID controller with the goal of minimizing the current distortion after harmonic suppression,According to the difference between the calculated harmonic current and the ideal current,the harmonic suppression of the ship power system is completed in the way of harmonic current compensation.The experimental results show that after the application of the proposed method,the current distortion of the ship power system is significantly changed,and the harmonic suppression can be completed in only 0.005 s.
