抄録

A combined cycle plant model for power system dynamic simulation studies has been developed. The major results of the research are as follows:<br>(1) Scope of the model: The unit plant in the large-capacity power station, which consists of the generator, the gas turbine and the steam turbine, is modeled. The unit plant is assumed to be operated in normal high output power (at least 60% of rated power). In the model, behavior of the output power, exhaust gas temperature, the fuel flow rate, and the air flow rate of the gas turbine, as well as the output power of the steam turbine are represented.<br>(2) Accuracy of the model: The results obtained by applying the developed model to dynamic simulations of an actual plant reveal that the model is in reasonable agreement with the static and dynamic behavior of the plant.<br>(3) Basic behavior of the plant under powersystem disturbances: Using the developed model, the basic behavior of the plant dynamics under power system disturbances such as system frequency change is demonstrated.
