中频发电机试验站调速系统的改造
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。由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控制系统进行必要的设备更新和技术改造。改造后的调速控制系统将原有的强电控制改造成以AT89C2051单片机为核心的计算机控制系统。此外，设计中将原有的人工手动控制改造为转速、电流双闭环自动控制系统。关键词：中频发电机；调速系统；AT89C2051单片机；双闭环自动控制系统；Reform of the Speed Adjustment System of Intermediate
Frequency Generator Test StationAbstract: In actual project, a lot of production machine requirements carry out the smooth regulation of speed in certain scope, and ask to have static and dynamic performance. Since the direct current motor has very good operation performance and control property, so the system of direct current of speed adjustment is major form of automatic speed adjustment system.
This paper introduces the direct current speed adjustment system. It is the domestic test system of the generator test station of intermediate frequency of the certain Military industry enterprise. The major task of the program is the necessary technical reformation and equipment updating for this speed adjustment control system. The reformed speed adjustment system transforms the original strong electronic-controlled system with the computer control system that takes single chip computer AT89C2051 as key. Besides, the design transforms the original artificial control by hand with two closed circuits automatic control system of speed and current. Key words: the intermediate frequency generator; the speed adjustment
System; single chip computer AT89C2051; two closed circuits automatic control system；
