Research on the Measuring and Calculating Methods of the Relative Internal Efficiency for Steam Turbine

Abstract:

The relative internal efficiency for steam turbine is one of the main economic indexes in evaluating the economic operation of steam turbine. It is usually obtained by thermal performance tests or online monitoring. In power plants, by means of measuring and calculating the relative internal efficiency for steam turbine, steam turbines’ thermal economy can be analyzed and diagnosed, and the safe operation and energy saving work can be directed. But there still exist some problems in measuring and calculating the relative internal efficiency for steam turbine at present. In this paper, the two defining methods of the relative internal efficiency are analyzed and compared. The connection of two kinds of relative internal efficiency and the same effect in evaluating the operation economy of steam turbines are indicated.Key words : Steam Turbine; Thermal Performance Test; Economic Index ;Relative Internal Efficiency
