摘要
针对大多数船用感应电机采用一台变频器控制一台电机,成本较高的问题,本文提出了用一台变频器控制两台电动机的方案,从而降低成本。首先以转子磁链的电流模型和单电机控制方法为基础,并利用Matlab中的Simulink软件构建了一台变频器控制两台并联异步电动机的模型。然后使用ODE45算法,对两台并联的异步电动机进行仿真分析。结果表明,两台电机的最终稳态磁链幅值与给定的磁链幅值相差不大。
In view of the high cost of controlling one motor with one frequency converter in most marine applications of induction motors,a scheme of controlling two motors with one frequency converter is proposed in this paper to reduce the cost.Firstly,based on the rotor flux current model and the control method of single motor,a converter control model of two parallel asynchronous motors is built using the Simulink software in Matlab.Then,ODE45 algorithm is used to simulate the two motors.The simulation results show that the final steady-state flux amplitude of the two motors differs little from the given flux amplitude.
