Early Faults and Characteristics of Large Capacity Non-salient Pole Synchronous Electric Machines

Large-capacity synchronous machines are prone to failure due to their complicated structure. The timely detection and processing in the early stage of the failure can avoid further expansion of the fault and avoid huge economic losses. By studying the structure of water-hydrogen-hydrogen turbine generators, this paper analyzes the types and characteristics of early faults of every component, and provides reference for the operation and state maintenance of synchronous machines.
