  • Rate of change of pressure temperature protection system for a turbine
    Patent number: 4655041
    Abstract: A method and apparatus for protecting a turbine from undesirable temperature and pressure variations wherein an acceptable range of actual pressure and temperature variations is established, a first alarm signal is generated only if the acceptable range is exceeded by actual temperature or pressure, a second signal is established representing an acceptable rate of change of said actual pressure or temperature and a second alarm is generated if the actual rate of change of pressure or temperature exceeds the acceptable range of pressure or temperature whereby the second alarm signal is produced only when the first alarm signal is generated. In addition, a third signal is established representing a maximum rate of change of pressure and a third alarm signal is generated if the actual rate of change of pressure or temperature exceeds the maximum rate of change of pressure or temperature whereby the third alarm signal is produced only when the first alarm signal is generated.
