Abstract

The invention aims to provide a fault detection method for a fuel supply system of a gas turbine, which comprises the following steps of: selecting operation parameters of the gas turbine, and establishing a curve of power, rotating speed, fuel supply pressure and fuel flow of the normal operation gas turbine by using historical data of the gas turbine, including an upper boundary, a lower boundary and a control center line; power parameters in the actual operation process of the gas turbine are collected to construct a to-be-detected sequence a, rotating speed parameters are collected to construct a to-be-detected sequence b, fuel supply pressure parameters are collected to construct a to-be-detected sequence c, and fuel flow parameters are collected to construct a to-be-detected sequence d; and selecting different SPC criterion combinations to carry out anomaly detection on the sequences a, b and c, and judging the state of the fuel system. The fault of the gas turbine fuel supply system can be effectively detected, and the gas turbine fuel supply anomaly detection method is simple, efficient, accurate and real-time.

Description

technical field [0001] The invention relates to a gas turbine detection method, in particular to a gas turbine fuel supply detection method. Background technique [0002] As an important power machine, the gas turbine has the characteristics of compact structure, stable operation, high thermal efficiency, etc., and its application range is becoming wider and wider. The safe and reliable work of gas turbines is very demanding. Under the daily working conditions of gas turbines, monitoring the health of the units and analyzing and detecting various possible abnormal situations can avoid or facilitate timely handling of large-scale failures of gas turbines. . [0003] Due to the complex working pressure of gas turbine fuel system pipelines, many pipelines and fuel components are prone to failure, resulting in failure of the fuel system. If the fuel supply system fails, it will cause the gas turbine to shut down, and if it is serious, it will cause a fire and the unit will be ...
