Title: (EN) DETECTION OF TEMPERATURE SENSOR FAILURE IN TURBINE SYSTEMS
(FR) DETECTION D'UNE PANNE DE CAPTEUR DE TEMPERATURE DANS DES SYSTEMES DE TURBINES
Abstract: front page image
(EN) There is described a method of detecting a temperature sensor failure in a turbine system, the method comprising (a) obtaining (102) individual measurement values from each temperature sensor in a group of temperature sensors, (b) calculating (104) a characteristic value for each temperature sensor in the group based on the measurement values for the corresponding temperature sensor, (c) selecting (106) a first characteristic value among the calculated characteristic values, (d) determining (108) a first maximum value as the maximum of the characteristic values except for the first characteristic value, and (e) determining (110) that the temperature sensor corresponding to the first characteristic value is defective if the first characteristic value is larger than the first maximum value multiplied by a predetermined factor. Further, a corresponding device, system, computer program and computer program product are described.
