摘　　要：主要对大型泵站同步电动机晶闸管励磁装置技术状况进行分析,介绍一种智能型励磁系统。通过互为热备用的双套微机控制系统具体设计,实现了智能监控恒励磁电压、恒励磁电流、恒功率因数和恒角度4种运行方式,单台电动机的自动控制运行,同时,可实现单站集中控制和远距离群站控制。实践证明该系统功能完善,运行性能安全可靠,适合在大型排涝泵站中推广应用。The technical condition of the large-scale pumping station synchronous motor excitation device of the thyristor was analyzed. An intelligent excitation system was introduced. By using each other hot spare sets specific design of the microcomputer control system, the intelligent monitoring constant excitation voltage, constant excitation current, constant power factor and constant angle of the four operating mode, and the auto- matic control of a single motor are realized. At the same time, the single station centralized control and long- distance station group control can be realized. Practice proves that the system is fully functional, safe and reli- able operating performance for large drainage pumping stations to promote the use.
