Abstract

This paper presents a mathematical representation of a combined cycle plant that is suitable for use in power system stability studies. The model incorporates gas turbine, heat recovery steam generator and steam turbine and includes speed control, temperature control and inlet guide vane control. A PID controller is designed for the governor-gas turbine system to improve system dynamic performance. The proposed combined cycle plant model and its controls are tested on a simple two-area power system. The performance of the combined cycle plant is investigated following system disturbances
