中頻發(fā)電機試驗站調速系統(tǒng)的改造
中頻發(fā)電機試驗站調速系統(tǒng)的改造摘 要：在實際生產(chǎn)中，有許多生產(chǎn)機械要求在一定的范圍內(nèi)進行速度的平滑調節(jié)，并且要求有良好的靜態(tài)、動態(tài)性能,使得系統(tǒng)在負載突變的情況下能快速的恢復穩(wěn)定。由于直流電動機具有極好的運行性能和控制特性，所以直流調速系統(tǒng)是自動調速系統(tǒng)的主要形式。
本文介紹的直流調速系統(tǒng)是國內(nèi)某軍工企業(yè)的中頻發(fā)電機試驗站的測試系統(tǒng)，課題的主要任務是對該調速控制系統(tǒng)進行必要的設備更新和技術改造。改造后的調速控制系統(tǒng)將原有的強電控制改造成以AT89C2051單片機為核心的計算機控制系統(tǒng)。此外，設計中將原有的人工手動控制改造為轉速、電流雙閉環(huán)自動控制系統(tǒng)。關鍵詞：中頻發(fā)電機；調速系統(tǒng)；AT89C2051單片機；雙閉環(huán)自動控制系統(tǒng)；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；
