Algorithm research of the automatic synchronization under difference frequence power grid using fuzzy control principle

In the power system,the automatic synchronization device plays an important role in operation of connecting between the generator and the power network.

This paper describes the design of generator synchronizing circuit of large power plants at present,analyzes possible problems thereof,and presents a method for over-all inspection and test on generator synchronizing circuit and automatic quasi-synchronizing devices,so that the generator synchronizing and closing can be safer and more reliable.

It points out some questions which must be given attention to in course of synchronizing and shows the necessity that we should apply the intellectualized automatic quasi-synchronizing device to synchronize.

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.
