Automatic Synchronization of a Newly Installed Generator to Infinite Bus of Bangladesh Power System

Installing a generator to the infinite bus requires its voltage, frequency and phase sequence to be synchronized with the bus. This synchronization process is done manually in Bangladesh's power system which possesses the risk of blackout as well as other security issues. To mitigate such problems, this paper proposes an automatic synchronization method and a practical demonstration of the method. The proposed method uses automatic PID controller to synchronize generator's voltage and frequency with the bus whereas phase sequence synchronization is done conventionally. The demonstration includes a single-phase induction motor as the prime mover of the synchronous generator and an Arduino Uno to implement the PID control. Successful synchronization is observed in the demonstration. This is an exemplary work of electric machine control applied to revolutionize maintenance of power system sustainability through automatic synchronization.
