具有一定的应用价值。

Abstract

On-line calculation of the main steam flow rate for a steam turbine is one difficult problem in monitoring the performance of thermal power units.The main affecting factors in on-line calculation of the main steam flow rate have been analysed

and the accuracy of existing calculation methods being compared.On the basis of Flügel formula

and combined with practical experiences in operation

a new calculation formula and its corrective method have been put forward

and taking a large-capacity steam turbine as an example for application

the calculation being carried out.Results show that the new calculation formula and its corrective method have higher accuracy

boasting a certain value for application.
