摘要:
A gas turbine performance analysis system includes a performance computation module for receiving an actual measured value of an inlet air temperature introduced to a compressor, a compressor pressure ratio, and a flow rate of fuel supplied to the gas turbine, and for calculating and outputting values of the gas turbine's power output and exhaust temperature based on these actual measured values. A performance estimation module evaluates the performance of the gas turbine based on the deviation between the values of power output and exhaust temperature outputted from the performance computation module and the actual measured values of power output and exhaust temperature. An adjustment module calculates a corrected value of the fuel flow rate based on the actual measured values of inlet air temperature, compressor pressure ratio and fuel flow rate, and inputs the corrected fuel flow rate value into the performance computation module.

A purchaser apparatus stores “anonymous order information including an order ID and purchaser identity verifying information” and “purchaser identity proving secret information”. A shop apparatus stores “anonymous order information including an order ID and purchaser identity verifying information”. If necessary, a purchaser sends a request including an order ID and zero knowledge proving information that a purchaser knows the purchaser identity proving secret information, from a purchaser apparatus to a shop apparatus. A shop apparatus verifies the zero knowledge proving information, based on purchaser identity verifying information retrieved from an order ID included in the request. Therefore, the unlinkability for past use is eliminated if necessary, and inconvenience caused by the unlinkability is eliminated.

A data processor connected to a peripheral device via a network includes an interceptor, a controller, and a peripheral device manager. The interceptor intercepts an access request for data stored in the peripheral device to issue a message indicating the interception and transmit the access request to the peripheral device. The controller determines, upon receipt of the message from the interceptor, whether to perform authentication based on configuration information of the peripheral device. Additionally, the controller determines, when authentication is to be performed, a mode for obtaining authentication data depending on whether an authentication library is installed. The peripheral device manager retrieves the configuration information from the peripheral device and transmits the configuration information to the controller.

A controller for use in a gas turbine power plant includes a compressor that compresses combustion air; a water-atomization cooling apparatus that sprays water drops of atomized water supplied via a water-atomization flow-rate regulating valve over a flow of air drawn in the compressor; a combustor that mixes the compressed combustion air with fuel to thereby burn a fuel-air mixture and generate combustion gas at high temperature and performs combustion switching during operation; a turbine that uses the combustion gas to drive the compressor and a generator; the water-atomization flow-rate regulating valve that controls a flow rate of the atomized water; and a compressor inlet inner blade that controls a flow rate of air drawn in the compressor. The controller includes control means that calculates a fuel-air ratio correction command signal for compensating for reduction in a fuel-air ratio in the combustor occurring during the combustion switching.

Disclosed is a solar assisted combined cycle power plant having a compressor that pressurizes combustion air, a combustor that mixes and burns the combustion air and gas turbine fuel to generate a high-temperature combustion gas, a gas turbine that drives the compressor by using the combustion gas, an exhaust heat recovery steam generator that obtains steam from thermal energy of a gas exhausted from the gas turbine, and a steam turbine that is driven by using the steam obtained by the exhaust heat recovery steam generator. The solar assisted combined cycle power plant includes a solar collector to turn supplied water to warm water; a heat accumulator that stores pressurized hot water from the solar collector and the exhaust heat recovery steam generator; and a spray device that handles the pressurized hot water as spray water and sprays the spray water onto the air to be taken into the compressor.

A group signature system includes a group manager device, a signer device and a verifier device capable of communicating with each other, each device using a group signature scheme. The group manager device generates a group secret key, a group public key, a member secret key and a signer tracing information. The signer device generates an encrypted text data of the signer tracing information, and a zero-knowledge proof showing that the signer device knows the member secret key and the encrypted text data is correctly generated based on the signer tracing information. The signer device transmits, to the verifier device, a group signature composed of the encrypted text data and the zero knowledge proof, and the message. The verifier device verifies correctness of the group signature and transmits the verified result to the signer device.
