A gas turbine control device comprises a frequency analyzing means for analyzing the frequencies inside the combustor of a gas turbine, a state grasping means for grasping the combustion state in the gas turbine on the basis of a state signal representing the result of the analysis by frequency band, the amount of operation process including a ratio between the air flow rate and pilot fuel in the gas turbine, the atmosphere state, and the load amount, a combustion characteristic grasping means for grasping the characteristic of the combustion vibration, and a control section for calculating a correction value of at least either the air flow rate supplied to the combustor or the pilot ratio from the grasped combustion vibration characteristic and the grasped combustion state each time the degree of the combustion vibration exceeds a predetermined control value, correcting the initial design values of the air flow rate and the pilot ratio predetermined correspondingly to the amount of operation process and the state signal, and thereby driving the gas turbine. The control section resets the correction of the initial design values when the degree of combustion vibration of the gas turbine is below the predetermined control value for a given period of time and operates the gas turbine using the initial design values.

摘要： A method of analysing blade tip timing data obtained from an array (P k ) of stationary timing probes (3) that are spaced at integer multiples of a base angle. Replace one of the probes (3) with a virtual probe (P v ) to give a virtual probe set (42). Set an initial probe angle (θ v ) and an initial engine order (EO v ) for the virtual probe (P v ). Calculate the condition number (CN) for the virtual probe set (42). If the condition number (CN) at least meets a threshold criterion, solve the virtual probe set (42) for blade tip displacement amplitude. Else increment the virtual probe angle (θ v ) and/or the virtual engine order and iterate from calculating the condition number. Else reinstate the replaced probe (3) and replace a different probe (3) from the array of probes (P k ) with the virtual probe (P v ); then iterate from setting the initial virtual probe angle and engine order.

摘要： On recourt à des capteurs immobiles (C1 à C8) pour mesurer périodiquement les mouvements vibratoires de portions (2) d'un corps (3) tournant devant eux, telles que des aubes, et rechercher leurs fréquences propres par des analyses de spectres. Conformément à l'invention, les capteurs sont regroupés en plusieurs réseaux de nombres différents et la recherche consiste en une comparaison des spectres des différents réseaux par diverses opérations de sélection et de rejet de raies.

摘要： A system and method for anomaly detection is provided. The system (100) and method (200) include utilizing one or more processors, such as in a server, for receiving (108) operational and dynamics data (104) from sensors associated with devices (102), filtering the data, establishing a set of baseline dynamics data and eliminating data dependencies (110). The system and method further include generating an expected level of data variation (112), identifying an anomaly based on a deviation of the device data from the baseline data normalized by the expected level of data variation (114), optionally correlating an anomaly with potential causes, and providing an output indicating an anomaly (116).
