Embodiment 1
[0045] The multi-parameter corrected remote vibration fault diagnosis method for turbo-generator sets in this embodiment includes: the establishment of a multi-parameter historical database and the diagnosis of vibration faults; wherein,
[0046] The establishment of the multi-parameter historical database: establish the standard numerical intervals corresponding to the corresponding parameters that affect the shafting vibration of the generator set when the rotor vibration data is normal;
[0047] Diagnosis of the vibration fault described:
[0048] Collect the real-time vibration data of each rotor of the shaft system of the steam turbine generator set, and simultaneously collect the real-time values of multiple parameters that affect the vibration of the shaft system of the generator set corresponding to the vibration vibration data;
[0049] output the acquired vibration data of each rotor to the front-end device, and the front-end device performs analog / digital conversi...
