Analysis of load efficiency characteristics of COGAG power plant based on dynamic simulation

With the application of dynamic simulation, whole-load-range load efficiency characteristics of the gas turbine plant, as well as the COGAG power plant are analyzed. The results show that whole-load-range load efficiency characteristics of efficiency versus power output of gas turbine can be shaped with parabolic curve. Economical performance of the COGAG power plant is greatly affected by its operation control method. The analytical results can provide scientific reference for design and optimization of control method of the power plant.
