双微机单独和协同控制下交流传动系统的研究

Study of the AC drive system with individual/co ordinated control of dual microcomputer

就交流电力机车逆变器并联运行过程中电流（负载）平衡分配存在的问题以及解决的方法进行了研究，分析了产生逆变器电流不平衡的原因，并提出了一个控制逆变器电流平衡的数学模型。根据该模型，设计了一套双微机单独协同控制系统。试验结果表明。

Study is made regarding the current distribution balance problem during the AC electric locomotive converter parallel operation,and the way to solve it.The reason to cause the current unbalance of the converter is analysed and a mathmatical model is proposed to control the converter current balance.A dual microcomputer individual/coordinated control system is designed according to the model.Test results show that this control methed is rational and viable.
