Considering the characteristic of fault diagnosis of large steam turbine unit for performance monitoring, a method for performance monitoring and fault diagnosis was designed based on versatile logical form. The logical form was proposed according to fault tree analysis. The diagnostic program can implement the entire process of fault analysis and diagnosis depending on the logical form. This method has characteristics of easy operation and good universality. Design idea and working process of the method were introduced by means of low feedwater temperature.

For the low pressure (LP) cylinder of a steam turbine, computation of the exhaust enthalpy is an important part in thermal power generating unit performance monitoring. A new online model for calculating the exhaust enthalpy was proposed aiming at the limitation of existing online calculation model for calculating the enthalpy of steam turbine LP cylinder exhaust steam. This model treats LP cylinder, condenser and corresponding heater as an open system, according to the energy balance equation of this open system, figuring out its exhaust enthalpy. Calculation results of typical steam turbine show that: in a large load change range, the results are close to thermal experimental value, the accuracy is similar to energy balance method.
