REGULATION SYSTEM FOR DOUBLE-SHAFT GAS TURBINES

摘要

"REGULATION SYSTEM FOR DOUBLE-SHAFT GAS TURBINES" A regulating system for regulating a double-shaft gas turbine, wherein simultaneously: the fuel feed electrovalve is governed by a signal proportional to the difference beetween the number of revolutions per minute of the power turbine and a reference value; the movable nozzles of the power turbine are governed by a signal ether proportional to the difference between the number of revolutions per minute of the compressor and a reference value; or proportional to the difference between the temperature of the exhaust gases and a relevant reference value; and the movable stator-blades of the compressor are governed by a signal proportional to the ratio between the revolutions per minute of the compressor to the square root of the ratio of the absolute ambient temperature to an absolute reference or design temperature.
