摘要： PROBLEM TO BE SOLVED: To provide a gas turbine controller contributing to stabilizing system frequency if the system frequency varies transiently, without having to set the material strength of gas turbine high-temperature components below the maximum stress of the high-temperature components.
SOLUTION: Control of gas-turbine combustion gas temperature is excluded so that, if a system frequency error is detected, adjusting the output of the gas turbine contributes to recovering the system frequency. For this, the gas turbine controller has a logic circuit which excludes the control of gas turbine combustion gas temperature according to a signal coming from the function of detecting system frequency errors, and a circuit which restores the gas turbine when the turbine is usable. The detection of system frequency errors may be effected by receiving external signals or by providing the controller in a combined cycle plant.

摘要： PROBLEM TO BE SOLVED: To prevent the flame failure of a gas turbine combustor caused by drain by preventing drain from staying in a fuel system not charged with fuel. SOLUTION: The gas turbine combustor system, which has a first fuel system 7 for supplying the gas turbine combustor 4 with fuel through a first fuel control valve 2 and a second fuel system 8 for supplying the gas turbine combustor 4 with fuel through a second fuel control valve 3 and has first and second fuel nozzles 20 and 21 at the outlet parts, respectively, from the first and second fuel systems to the gas turbine combustor 4, has means 6 and 25 which let dry gas (compressed air) flow to the first fuel system 7 when fuel is not flowing to the first fuel system 7. The flow rate of the compressed air is controlled to increase first to a first flow rate, and then decrease to a second flow rate smaller than the first flow rate, and then, keep this second flow rate.

摘要： PROBLEM TO BE SOLVED: To find out a damage on a blade and the like in an early stage by calculating a compressor efficiency, calculating a reduced efficiency by a correction efficiency found out from a compressor inlet temperature in a rated condition and a correction efficiency found out from an inlet guide blade opening in the rated condition, and monitoring the reduced efficiency. SOLUTION: In an efficiency monitor of a compressor, a compressor efficiency ηreal is calculated from a compressor pressure ratio, a compressor delivery temperature, a compressor inlet temperature CTIM, and a specific heat ratio of an operating fluid. The compressor efficiency is reduced to a rated condition by ηconv =ηreal -ΔηCTIM-ΔηIGV ηconv is a reduced efficiency, ΔηCTIM is a correction efficiency by an IGV opening. In a monitor device, the ηconv reduced in the rated condition is monitored, and it is judged that a moving blade of the compressor or a part of a stationary blade is broken when the value is reduced more than a setting value. It is thus possible to find out a damage on a blade and the like of a compressor automatically and precisely.

摘要： PROBLEM TO BE SOLVED: To provide a fuel valve opening degree control system for preventing failure of operation of a valve element of a fuel adjusting valve without having influence on output load, and performing good fuel control.
SOLUTION: An opening degree variation function generator 14 gives an opening degree variation instruction value to any of two or more fuel adjusting valves 12 when an combustor 11 runs at constant load, while a opening degree variation correcting function generator 16 gives an opening degree variation compensating instruction value for offsetting fuel flow rate variation against the opening degree variation instruction value to the rest of the fuel adjusting valves 12. Thereby, opening degree of the fuel adjusting valve 12 can be varied while holding load-constant running, so that failure of operation of the valve element can be prevented.

摘要： PROBLEM TO BE SOLVED: To specify the position where an abnormality occurs quickly when the abnormality is detected in a gas turbine compartment 2.
SOLUTION: State quantity measuring devices 3 are provided so that the state quantity of at least one of gas concentration, vibration noise, temperature, etc., in the gas turbine compartment 2 can be measured at a plurality of places. If an abnormality occurs in the gas turbine compartment 2, the distribution of gas concentration in three dimensional space is determined based on signals from a plurality of the state quantity devices 3, and the highest gas concentration position out of the distributed concentration position is taken as the highest gas concentration point. A measuring point showing the gas concentration nearest to this highest gas concentration point out of measuring data in a plurality of measuring points adjacent to the highest gas concentration point is determined, and the determined point is taken as the adjacent highest gas concentration point. This makes it possible to specify a gas leakage position between the highest gas concentration point and the adjacent highest gas concentration point.
