摘要
为了研究不同励磁方式对采用脉冲宽度调制(PWM)斩波调速系统的矿用直流电机车的运行性能,以探究更适于矿用直流电机车作业条件的励磁方式,建立了电机车PWM斩波调速仿真模型,并结合矿用直流电机车运行条件,对其在3种不同励磁方式下的运行性能(包括启动性能、调速性能、动态性能)进行了仿真和比较。仿真结果表明:他励方式的矿用直流电机车更加适用于额定负载长距离运输;串励方式的矿用直流电机车较适用于频繁启动和要求功率为定值的场合。研究结果对矿用直流电机车斩波调速系统的应用和学习提供理论指导和借鉴。
In order to study the operation performance of mine direct current（DC） motor vehicle adopting pulse width modulation（PWM） chopper speed regulation system with different exciting mode,to explore more suitable exciting mode for minie DC locomotive operating conditions.A simulation model for PWM chopper speed regulation for electric locomotive is established,combined with the operating conditions of the mine DC electric locomotive,the operation performance（including starting performance,speed regulation performance and dynamic performance） in three different excitation modes are simulated and compared.The simulation results show that the DC locomotives separately exciting mode is more suitable for long distance transportation of rated load; DC locomotives series excitation mode is suitable for the occasion that frequent start and power requirements of fixed value.The research provides theoretical guidance and reference for the application and learning of the chopper speed regulation system of the mine DC locomotive.
