转子磁场定向矢量控制在矿用电机车上的应用

Rotor flux oriented vector control in the mining application of the motor vehicle

结合矿用电机车的工作状况,研制开发出基于DSP的SVPWM变频调速系统。该系统采用转子磁场定向矢量控制方案,显著减小逆变器输出电流谐波成分及电机谐波损耗,提高电压利用率,提高电机车的工作性能,对提高矿山企业的经济效益和社会效益是非常重要的。

In response to the status of mining electric locomotives,develop frequency control system of SVPWM for mining electric locomotives based on DSP.The system adopts the rotor field-oriented vector control scheme.It is significant to reduce current harmonic components outputted by the inverter and it can raise voltage utilization ratio,that system can improve the working performance of electric excavator,and it is very important to enhance the economic and social benefits of the mining enterprises.
