1. In a system for monitoring steam turbine blade temperature utilizing measurement parameter values, a graphical user interface utilizing a computer for displaying a menu so as to allow selection for viewing of any of the following turbine diagram windows:

  • turbine overview;

    HP turbine;

    LP1 turbine;

    LP2 turbine;

    any other turbine included within the system;

    wherein for each turbine, view windows selectable through said menu are provided, including;

    turbine overview, actual on-line turbine condition on a Mollier diagram, and a trend diagram window;

    said turbine overview window displaying a current value of blade temperature; and

    said Mollier diagram and said actual turbine condition on said Mollier diagram being generated automatically by said computer based on thermodynamic calculations and blade temperature estimation by a hybrid artificial neural network.
