摘要： A gas turbine protection apparatus, which can output a gas turbine protection signal only when a combustor is abnormal, without increasing the number of temperature sensors such as thermocouples. For this purpose, a BPT deviation change amount large automatic stop signal is outputted when a BPT deviation change amount of any of the thermocouples exceeds a BPT deviation change amount large set value, and a BPT deviation change amount large signal is outputted from a determining section (15), and when the BPT deviation change amount of any of the thermocouples adjacent bilaterally to the any thermocouple exceeds a BPT deviation change amount present set value, and a BPT deviation change amount present signal is outputted from a determining section (16a, 16b). Alternatively, a BPT deviation great automatic stop or tripping signal is outputted when a BPT deviation of any of the thermocouples exceeds a BPT deviation great set value, and a BPT deviation great signal is outputted from a determining section, and when the BPT deviation of any of the thermocouples adjacent bilaterally to the any thermocouple exceeds a BPT deviation present set value, and a BPT deviation present signal is outputted from a determining section.

摘要： In a contact for a connector, a metal material id processed to be bent in a predetermined shape in a manner so that a terminal portion is formed in the vicinity of an end and a contacting portion is formed in the vicinity of the other end. A nickel plating layer as a foundation plating layer and a gold plating layer are formed on substantially entire surface of the contact including the terminal portion and the contacting portion. Laser beams are irradiated at a portion between the terminal portion and the contacting portion, and especially in the vicinity of the terminal portion so that the nickel plating layer as the foundation plating layer is unsheathed by removing the gold plating layer or gold in the gold plating layer and nickel in the foundation layer are alloyed. Nickel and the alloy of nickel and gold respectively have low wetting property with respect to solder, so that diffusion of melted solder stops at the portion.

摘要： A gas turbine control apparatus for a single-shaft type combined cycle power plant is provided by which gas turbine output is accurately computed during a circulating water reversing wash operation. Vacuum down amount is computed from a generator output signal (31) immediately before the mentioned reversing wash operation and is corrected by being multiplied by a valve opening correction factor computed from a condenser reversing valve opening signal (41) and a sea water temperature correction factor computed from a condenser reversing valve inlet sea water temperature signal (47). A condenser vacuum at the time of the reversing wash operation is computed by the corrected vacuum down amount being subtracted therefrom. A vacuum correction factor is computed based on the computed condenser vacuum. A reference steam turbine output is computed based on a post-intercept valve steam pressure signal (34) and a steam turbine output signal (54) is computed by multiplying the reference steam turbine output by the vacuum correction factor. A gas turbine output signal (55) is computed by subtracting the steam turbine output signal (54) from the generator output signal (31).

摘要： A gas turbine plant for limiting a sudden increase of load of the gas turbine, i.e., of the amount of fuel, and suppressing a stress of the turbine, or for maintaining a suitable fuel-air ratio is disclosed. The plant includes a controller comprising a section for calculating a governor signal for controlling the degree of opening of the fuel valve, based on a revolution speed of the gas turbine; and a section for calculating a load-limiting signal for following the governor signal, wherein when the governor signal decreases, the load-limiting signal is larger than it by a predetermined value, while when the governor signal increases, the increase rate of the load-limiting signal has a predetermined upper limit. The controller also comprises a limiting section, into which both signals are input, for limiting the upper value of the governor signal by using the load-limiting signal as an upper limit.

摘要： A gas turbine has a plurality of combustors in a toroidal arrangement to provide combustion gases to turbine blades, thereby rotating the turbine body. Thermocouples, the number of which is the same as or greater than the number of the combustors, are arranged toroidally at the outlets of the turbine blades and measure the temperatures of the combustion gases at the respective outlets. During the operation of the gas turbine, if an abnormality, such as misfire or fuel injection nozzle obstruction, occurs in one or more of the combustors, the resulting change in gas temperature triggers a signal to stop, and thereby protect the gas turbine. Based on the measured values of the blade pass temperatures of the thermocouples and set threshold temperatures, a fuel supply system may be caused to gradually decrease the fuel supplied to the combustors to bring the gas turbine body to an automatic stop, or it may be cut off instantaneously, thus immediately stopping the gas turbine.
