摘要
利用考虑铁损的推进电机等值电路模型,通过数值计算方法寻找推进电机不同转速及负载下对应的最佳效率。改进了恒磁通的传统矢量变频控制方法,以实现电机最小能量损耗;探讨了节能运行控制方法的适用范围。仿真实验数据表明,改进后的控制方法可在相当宽广的运行区域内提高电机的运行效率,并保证系统不损失动态响应特性。
The iron-loss model of the asynchronous marine propulsion motor is applied to find out mum point against different speeds and loadings. Traditional constant-flux chieve minimum-loss control and the application range of the energy-saving results indicate that the modified vector control strategy can enhance motor vector control me control method is tho dis the efficiency opti- d is modified to a- cussed. Simulation running efficiency in a wide operationalrange without losing its dynamic characteristics.
