Title: (EN) DETECTION OF TEMPERATURE SENSOR FAILURE IN TURBINE SYSTEMS
(ZH) 涡轮机系统中的温度传感器故障检测
Abstract: front page image
(EN) The invention discloses 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 ina 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.
(ZH) 本发明公开了一种检测涡轮机系统中的温度传感器故障的方法,包括:(a)从一组温度传感器中的每个温度传感器获取(102)各自的多个测量值,(b)基于对应的温度传感器的多个测量值,计算(104)一组中的每个温度传感器的一个特征值,(c)在所计算的多个特征值中选择(106)第一特征值,(d)将多个特征值中除第一特征值以外的最大值确定(108)为第一最大值,以及(e)如果第一特征值大于第一最大值与一个预定系数的乘积,则确定(110)与第一特征值相对应的温度传感器是有缺陷的。此外,还公开了对应的设备、系统、计算机程序和计算机程序产品。
