摘要
针对电动船舶中电力系统的谐波抑制问题进行研究。首先分析电动船舶电力系统中谐波产生的主要原因及谐波特点;其次,针对船舶推动电力系统中的整流器对谐波产生的影响,采用了三相电压型PWM整流器对其进行改进,抑制电力系统中谐波的产生;由于高次谐波成分并没被滤除干净,因而在供电网侧与PWM整流器之间增加了L型滤波器对剩余谐波进行滤除。最后,利用Simulink仿真器对本文算法进行仿真验证,结果证实算法对谐波滤除的有效性。
This paper studies the electric power system harmonic control problems in the electric ship. First of all,we analyzed the main reasons for the harmonic in electric ship power system and the characteristics of harmonic. For reducing the rectifier influence on harmonic,we adopted the three-phase voltage source PWM rectifier to suppress the harmonic generation in power system. Then,we added the L type filter between the supply network side and the PWM rectifier for cleaning the rest of the higher harmonic components. Finally,we used Simulink to simulate the method. The experimental results show that the method can effectively reduce the harmonic in ship power system.
