Synchronization Digital Device Development for Generators Automatic Connection to the Network by Various Methods

Abstract

Synchronization is an actions algorithm to turn on synchronous generators for parallel operation with other synchronously rotating machines or an electric energy system (EES). This operation is a generation process composite part. At the moment there are two traditional ways of doing it: ideal synchronization and self-synchronization manually by personnel or using automatic devices. Synchronization can have various consequences: large equalizing current, power plant busbar de-energization, damage to switching equipment or synchronous generators. They depend both on the chosen implementation method and on the human factor influence. The unit starting possible consequences minimizing necessitates an automatic device development that excludes the human factor influence and some modernized synchronization method that eliminates the two traditional methods disadvantages. The creation of such a synchronization system will solve the problem of possible consequences from the synchronous generator inclusion in network.
