The arrangement of measuring points in conventional performance test of steam turbines is limited

the measuring parameters are generally confined to related parameters of the high pressure heater

deaeator

and those related to secondary class correction

making various analysis methods of the thermal system to be difficult for accurately carrying out partial quantitative analysis on the basis of said measured parameters. Through strictly theoretical analysis and mathematical deduction

a new method for carrying out the partial quantitative analysis under condition of limited parameters in conventional performance test of steam turbines has been firstly put forward. The new method has features

such as universal

accurate

and suitable for routinization in computers

and it is especially suited to use for the partial quantitative analysis in conventional performance test of steam turbines

and having been validated through practical examples.
