Fitting and simulation of characteristic curve of micro gas turbine compressor

Abstract

Microturbine is widely used in distributed power generation systems and is the core energy exchange equipment of integrated energy systems. Among them, the characteristic curve of the compressor is very important in the establishment of the simulation model of the Microturbine. However, under variable working conditions, the physical process inside the compressor is complex, and currently there is no accurate theoretical formula to describe the characteristic curve of the compressor. In this paper, the characteristic curve of the compressor was obtained by using the equation fitted according to the existing data and combining with the interpolation method, and the simulation model of the Microturbine was established based on MATLAB/Simulink to analyze the characteristics of the compressor. The simulation results showed the accuracy of the fitting curve obtained by this method.
