An Investigation of a New Method to Detect Lossess of Excitation of Synchronous Generators

Milad Niaz Azari; Reza Fathi shoob

Volume 4, Issue 1 , January 2021, , Pages 115-126


  Synchronous generators are one of the most important components of power systems. Problems a generator may face are internal faults, system disturbances, or operational hazards. The operation of a generator may easily be affected by faults within the machine itself as opposed to external disturbances ...  Read More
