国电四维高压变频器在唐山德龙钢铁公司同步电动机的应用

高压同步电动机以其功率因数高、运行转速稳定、低转速设计简单等优点在高压大功率电气驱动领域有着大量的应用。但同步电动机物理过程复杂、控制难度高的特点，一直制约着同步电动机的变频应用。国电四维公司技术人员经过大量的理论分析、仿真、实验，解决了诸多关键问题．已于2012年底成功地将SWdrive系列高压变频器应用于唐山德龙钢铁公司的4200kW／10kV同步电动机上，本文将简要介绍应用的相关情况。

Application of Guodian Siwei High-voltage Inverter in Tangshan Delong Stee Synchronous Motor

High Voltage Synchronous Motor with high power factor, stable operating speed, low speed and simple design has a lot of applications in the field of high-voltage high-power electrical drive. But synchronous motor complex physical processes and controlling the characteristics of high difficulty, has restricted the application of synchronous motor inverter. Guodian Siwei company＇s technical staff through a lot of theoretical analysis, simulation, experiment, solve many critical issues, which successfully SWdrive series of high-voltage inverter used in Tangshan De Long Steel＇s 4200kW/10kV synchronous motor in the end of 2012, this paper will briefly describes the application of the relevant circumstances.
