Abstract: 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.

Abstract: A method for evaluating and modifying the operating conditions of a machine or an installation includes measuring at least one parameter a number of times to create a database, of the parameter, determining an extrapolation range, performing an extrapolation in the range, and determining a measure of quality, K, of the extrapolation calculated on the basis of the database. K is a function of at least two variables. The parameter value is controlled so that the value will be retained within a limit.

Abstract: A diagnostic method and system for a technical installation establish the cause of a fault event. A reliable, flexible and simple possible way of diagnosing an installation is provided by placing state variables that characterize an operating state of the technical installation in a dependency tree and establishing a fault path in the dependency tree by linking change directions of diagnostic parameters contained in the dependency tree.

Abstract: Optimal adjustment of the extrapolation function in respect of the database is effected according to the invention not by means of a maximum correlation coefficient r but using a measure of quality K, which is independent of the gradient of an adjustment curve in respect of a database.
