Abstract: The features of equipment and main bus connection in 1000 MW generator set were produced. The configuration scheme of protection was proposed, and the requirement of type selection for loss-of-excitation protection, stator earth fault protection and rotor winding earth fault protection were put forward too. It was pointed out that one of the measures to ensure the safe and economy operation of 1000 MW generator set is to increase redundancy of hardware system of protection device.
