Development of Automatic Quasi-synchronization System with Double Microcomputer

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.
