The invention relates to a method for identifying the operating condition of a turbine during operation. According to said method, a hot waste gas flows through a waste gas housing and the temperature of the waste gas in said housing is detected using temporal resolution. The aim of the invention is to provide a method for identifying the operating condition of a turbine during operation, which identifies and displays systematic errors. To achieve this, the numerous measured temperature values for the waste gas are respectively detected using local resolution with reference to the origin of an imaginary Cartesian co-ordinate system. The focal point of the temperature distribution is then determined, a vector between the origin of the Cartesian co-ordinate system and the focal point of the temperature distribution being used as an indicator for the operating condition of the turbines.

The invention claimed is: 1. A method for identifying an operating state during an operation of a turbine having an exhaust gas flowing through an exhaust gas housing downstream of the turbine, comprising:detecting temperature values of the exhaust gas in the exhaust gas housing in a time-resolved fashion and in a plane transverse to principal flow direction of the exhaust gas;measuring the temperature values of the exhaust gas in a spatially resolved fashion with reference to an origin of an imaginary Cartesian coordinate system;projecting the measured temperature values into two axes of the imaginary Cartesian coordinate system;decomposing the measured temperature values into two spatial components perpendicular to one another;directing the two spatial components either positively or negatively at the imaginary Cartesian coordinate system;calculating a moment from a lever arm that is pivoted at two reference values of the two axes of the imaginary Cartesian coordinate system;summing up moments for the two axes to form two oppositely directed moment sums;evaluating the two reference values from the two moment sums;composing a point from the two reference values as a centroid of the temperature distribution; andidentifying the operating state of the turbine based on the centroid of the temperature distribution.
