<P>PROBLEM TO BE SOLVED: To improve accuracy of misfire detection in a gas turbine plant operating with taking high temperature gas therein. <P>SOLUTION: The gas turbine plant is provided with a compressor, a combustor burning first fuel, a turbine, a generator driven by the turbine, an output detector detecting output of the generator, a first fuel valve controlling flow rate of the first fuel supplied to the combustor, and a first fuel valve control part generating first fuel valve opening command value based on output detection value and output target value and operating opening of the first fuel valve. A storage part storing first fuel misfire determination criterion and a misfire determination part generating misfire signal indicating misfire in the combustor when the first fuel valve opening command value exceeds the first fuel misfire determination criterion are provided to determine misfire of such a gas turbine plant. <P>COPYRIGHT: (C)2007,JPO&INPIT |
