采用多单元同步控制系统，考虑到煤矿的现场情况和控制距离, 在设备机头设有本地/遥控转换开关，既可实现本地控制, 也可远程遥控。3台变频器之间通过开放的RS-485串行通讯网络进行实时通信，实现数据交换。在运行中，可以在控制室通过工控机对3台高压变频器同时给定同步速度，实现良好的同步关系。

高压变频器系统图如图３所示。

运行中的高压变频器如图4所示。

5.VT710高压变频器特性

 （1）满载时，包括移相变压器在内的变频调速系统效率≥97%；

 （2）功率因数≥95%；
 （3）满足中国谐波相关标准；
 （4）适用6000V 普通异步电机；
 （5）近似全数字PWM脉宽调制技术；
 （6）全功率范围段的MCU控制；
 （7）PWM输出电压波形控制在VDC内；
 （8）直接矢量闭环控制模式，控制精度万分之一；
 （9）在闭环矢量控制模式下，VT710的控制范围是1:100，即以50Hz为基频，其控制范围可到0.5Hz。在开环情况下，VT710的控制范围也
      可达到1:10，也就是5Hz；
 （10）电流跟踪和磁通补偿功能；
 （11）主要功能：转差补偿,电机参数自学习,瞬停再启动,多段速,重拾,高效运行，比例联动,频率跳跃；
 （12）保护功能:过电流限制,过电压限制,过负荷预警,过电流跳闸,过电压跳闸，CELL功率单元故障跳闸,过负荷跳闸,接地故障跳闸,过
       热跳闸,其它；
 （13）显示:输出频率，电机转速，电机电流，输出电压，电机输出功率，各功率单元DC电压，运行时间，故障查询，变频器温度，其它。

6.VT710变频调速系统与交流绕线式电机串电阻调速系统的比较
  6.1 VT710与电机串电阻调速相比，有以下突出特点：

  (1)起动性能优越
       变频器采用速度闭环控制，调速精度高，启动转矩可以做到等于最大输出转矩；即使在零速也可以达到最大转矩。串电阻调速起动过程和调速换挡过程中电流冲击大。
  (2)系统效率高
       变频器输出直接和电机相连接，效率高；绕线式电机转子串电阻调速，电阻上消耗大量的转差功率,效率极低。 
  (3)负载特性良好
      变频器负载可以在很大的范围来调节；绕线式电机转子串电阻调速范围有限。

  (4)维护成本低
      变频器的运行成本和维护成本却远远比串电阻调速低。串电阻调速的日常维护比变频器工作量大，维护成本高。

  6.2变频器系统和绕线式电机转子串电阻系统综合比较
     变频器系统和绕线式电机转子串电阻系统综合比较如附表所示。
