摘　　要：基于现有流速仪检定车调速系统不能满足声学多普勒流速仪检定规程,流速仪检定车的调速系统需要重新设计。通过调速电机分析比较,同步电机变频调速对流速仪检定车的调速系统最为适合。同步电机为恒转速电机,但负载变化会引起同步转速下功率角的摆动。针对不同性质的负载对同步转速的影响,通过分析同步电机瞬态过程特性,并结合反馈控制电路实验,得出利用反馈控制提高同步电机瞬态过程特性的结论。The existing Current Meters Calibration Vehicle Velocity Governing System （CMCVVGS） cannot satisfy the verifica- tion procedures of the acoustics Doppler current meters,CMCVVGS need to be redesigned.Through analysis and comparison of the adjustable-speed motors, synchronous motor frequency control in Current Meters Calibration Vehicle （CMCV） is generally considered to be the most suitable method.Synchronous motor is a constant velocity motor,but the load change will lead to the swing of power angle under the synchronous velocity.By analyzing the characteristics of the transient process of the syn- chronous motors and combine with the simulated experiments of control circuit, reaching the conclusion that feedback control can improve the transient process characteristics of synchronous motors.
