中频发电机试验站调速系统的改造
vestas中频发电机试验站调速系统的改造摘要:在实际生产中，有许多生产机械要 求在一定的范围内进行速度的平滑调节，并且要求有良好的静态、动态性能，使 得系统在负载突变的情况下能快速的恢复稳定•山于直流电动机具有极好的运行 性能和控制特性，所以直流调速系统是自动调速系统的主要形式.
本文介绍的直流调速系统是国内某军工企业的中频发电机试验站的测试系 统，课题的主要任务是对该调速进行必要的设备更新和技术改造。改造后的调 速将原有的强电控制改造成以AT89C 2 0 5 1单片机为核心的计算机。此 外，设计中将原有的人工手动控制改造为转速、电流双闭环自动。关键词：中 频发电机；调速系统；AT89C205 I单片机;双闭环自动;高考数学辅导Reform of the Speed A dj u stm e nt Sy s tem of I nt e r m e d i a te
