GAS TURBINE APPARATUS

摘要

A gas turbine apparatus has a turbine controller. The turbine controller determines a theoretical opening value of the valve from an air/fuel ratio upon ignition of the gas turbine, and calibrates the opening instruction value after the ignition based on an opening difference between the theoretical opening value and the opening instruction value. The air/fuel ratio is calculated based on the temperature of air to be mixed with the fuel upon ignition of the gas turbine. The apparatus further comprises at least one sensor for measuring a physical amount of at least one object to be measured; an error detector for detecting an error between a current value measured by the sensor and a predetermined reference value; means for modifying the current value based on the error detected by the error detector; and means for providing the modified current measured value to the turbine controller.
