Abstract

The invention, which belongs to the field of gas turbine fault diagnosis, relates to a gas turbine fault diagnosis method and device. The method comprises the steps that: thermal performance parameters of each component in multiple components of a gas turbine are obtained, wherein the multiple components comprise a gas compressor, a combustion chamber and a turbine; mechanical vibration parametersof each unit in a plurality of units included in each component, wherein the mechanical vibration parameters are obtained according to vibration signals output by an acceleration sensors, each unit is provided with one acceleration sensor, and the plurality of units including blades, bearings and rotors; a faulty component is determined according to the obtained thermal performance parameter of each component; a fault unit is determined according to the mechanical vibration parameters of each unit of the faulty component, wherein the fault unit is a unit having a fault in a plurality of unitsincluded in by the faulty component. Therefore, a problem of low diagnosis precision of gas turbine fault diagnosis in related technologies is solved; the diagnosis precision of gas turbine fault diagnosis is improved, and the gas turbine fault diagnosis method and device are used for diagnosing gas turbine faults.

Description

technical field [0001] The invention relates to the field of gas turbine fault diagnosis, in particular to a gas turbine fault diagnosis method and device. Background technique [0002] In the construction and operation of natural gas pipelines, the operation of the gas turbine as the main driving machine of the compressor is one of the important issues that people pay attention to. The gas turbine has the advantages of compact structure, stable operation, safety and reliability, quick start and load driving, and high thermal efficiency. Once a gas turbine fails, it will have a serious impact on production and operation. Therefore, it is more and more important to quickly and accurately diagnose the fault when the gas turbine fails and deal with the fault in time to ensure the normal operation of the gas turbine. [0003] In the related art, the failure of the gas turbine is usually determined based on the thermal performance parameters (such as temperature or pressure par...
