Abstract

The embodiment of the invention provides a gas turbine fault early warning method and device, and belongs to the field of thermal power generation. The method comprises the following steps: detectinga plurality of sets of current parameters of a gas turbine; calculating the Mahalanobis distance of a plurality of groups of current parameters of the gas turbine according to a reference space obtained by a plurality of groups of normal parameters of the gas turbine; and determining whether the gas turbine is in fault or not according to the Mahalanobis distance of the current parameters based onthe reference space. The invention can realize fault early warning and diagnosis of the gas turbine and ensure the operation safety of the gas turbine.

Description

technical field [0001] The invention relates to thermal power generation, in particular to a gas turbine failure early warning method and device. Background technique [0002] As a new type of power equipment, gas turbine has the advantages of less pollution, high efficiency, strong flexibility, and compact structure. The efficient operation of gas turbines has a great impact on the safety and economy of industrial systems, so gas turbines are the key research objects of the Industry 4.0 strategy. Due to the complex structure of the gas turbine, and has been working in the harsh environment of high temperature, high pressure and high speed, it is easy to cause various failures, and the reasons for the failures are very complicated. It is difficult to find out in time and make correct judgment and treatment only by technicians. Therefore, in order to further improve the stability and reliability of the gas turbine operation process and reduce the frequency of accidents as mu...
