摘　　要：先进的三维物探船是电力推进形式的科考船,配置有变频控制的大功率推进电机和震源空压机,电站谐波必须进行控制,否则将导致高精度信号的采集和运算产生较大误差。文章以国内首艘自主设计的某三维物探船为例,根据投资预算、谐波控制指标、勘探作业特点、动力冗余等要求,对变频器选型论证、对发电机参数调整,制定全船谐波的综合治理方案,对同类船舶动力系统的设计具有借鉴意义。The advanced 3D seismic survey vessel is a research ship with electrical propulsion system.Equipped with high-power frequency convertor of propulsion motors and seismic compressors,the harmonics of the power system is heavy and must be suppressed,if not,the high-precision signal detected and processed will be seriously affected.In the article,taking the first self-designed 3D seismic vessel as an example,it introduces the integrated harmonic control scheme according to investment budget,THD specification,researching characteristics,power redundant requirements,selection of frequency converter model and adjustment of generator parameters and so on,which has reference values for the power system design of the similar vessels.
