Problems solved by technology
At present, the shafting fault diagnosis system uses the analysis of vibration information as the main technical means. It can judge whether the fault of the turbogenerator set is faulty and determine the type of fault. development, the accuracy and efficiency of staff maintenance cannot meet the actual requirements, and consume a lot of manpower and material resources. Therefore, there is an urgent need for a technology that can determine the cause and location of vibration faults

The invention provides a fault determination method and system for a steam turbine generator unit. The method comprises the steps that fault vibration data generated when the steam turbine generator unit breaks down are obtained; the fault vibration data comprise multiple kinds of vibration factor data; the fault type of the steam turbine generator unit is determined according to the fault vibration data; multiple state parameters capable of causing the fault type in the steam turbine generator unit are obtained; a fault type parameter matrix is constructed according to the state parameters and the fault vibration data; and the fault reason and the fault position of the steam turbine generator unit are determined according to the fault type parameter matrix. According to the method and system, the fault type parameter matrix is established, and the fault reason and the position can be determined so that a worker can timely determine a fault repair scheme.
Description
technical field [0001] The invention relates to the technical field of monitoring a turbogenerator set, in particular to a fault determination method and system for a turbogenerator set. Background technique [0002] The fault diagnosis and treatment technology of steam turbine generator set is an applied engineering discipline, involving many fields such as vibration mechanics, rotor dynamics, vibration measurement, vibration fault diagnosis, equipment design, equipment operation and maintenance, etc. At present, the shafting fault diagnosis system uses the analysis of vibration information as the main technical means. It can judge whether the fault of the turbogenerator set is faulty and determine the type of fault. Development, the accuracy and efficiency of staff inspections cannot meet the actual requirements, and consume a lot of manpower and material resources. Therefore, a technology that can determine the cause and location of vibration faults is urgently needed. ...
