Abstract:
A method for monitoring at a remote monitoring center a turbine driven by a supply of high temperature combustion gas generated by combustion in a combustor, the method comprising:first receiving and monitoring a second data including representative values within a predetermined period of time in a first communications mode at a plant in which the turbine is installed, wherein the second data is generated based on a first data concerning a combustion oscillation of the combustion gas in the combustor obtained on a real-time basis in a normal state; and second receiving and monitoring the first data from the plant in a second communications mode at a speed which is higher than a speed of the first communications mode in the event of an abnormal state in which the second data is close to a value representing a predetermined critical state, wherein an instruction is sent to the plant to reduce turbine operation power when a symptom is detected of the predetermined critical state from the monitored first data.
