摘要
针对传统的手动自动准同期系统存在合闸时机难把握、不能自动调节等缺陷,文章提出了一种采用双微机控制的智能化准同期系统,介绍了该同期系统的实现方法、软件设计和系统特点。该同期系统采用PID和双微机综合控制的方法,实现了快速跟踪电压和频率、自动调节待并发电机组的功能,能确保系统同期时精确无误地将断路器合闸。实际应用证明了该同期系统性能良好。
Aiming at the shortcomings of traditional manual automatic quasi-synchronization system such as switching time is difficult to control and automaticly regulate, the paper put forward an intelligent quasi-synchronization system controlled by double microcomputer, introduced implementation method, software design and characteristics of the synchronization system. The synchronization system adopted control method with PID and double microcomputer technology , and realized function of tracking voltage and frequency rapidly, automatic regulating generators, which could ensure to switch on the breaker correctly when the system is synchronous. The practice result proved this kind of synchronization system has good performance.
