摘    要：湖南华菱湘潭钢铁有限公司新建高速线材生产线,传动系统采用国产同步交流变频电动机,电控系统采用ABB三电平中压变频器ACS 6000 SD,变频器功率元件采用IGCT。介绍了电控系统硬件配置,对传动硬件选型和同步电动机励磁控制方式选择等进行了对比和分析,着重介绍了整流单元同步电压与主回路电压相序校验方法和逆变单元对电动机转子绝对位置编码器位置偏差的调试。另外对系统在试运行期间发生的一些典型故障作出分析、判断和总结,为今后系统故障处理提供一定的参考思路。

Abstract: For newly-built high speed wire production line of Hunan Valin Xiangtan Iron & Steel Co.,Ltd.,AC variable frequency synchronous motor,made in China,was adopted in drive system,ABB three level medium voltage frequency inverter ACS 6000 SD was used in electrical control system,and power element of inverter was IGCT.Hardware configuration of electrical control system is introduced.Selection of drive hardware and choice of exciter control mode of synchronous motor are compared and analyzed.Debugging of rectifier unit and inverter unit is discussed.Phase sequence checking method of rectifier unit synchronous voltage and main circuit voltage is introduced,and debugging steps of inverter unit position deviation of rotor absolute position encoder is described.Analysis and judgement of some typical faults during test running of the system are summed up.It provides a reference for troubleshooting in future.
