1D 시뮬레이션 프로그램을 활용한 발전용 가스터빈 열성능 해석 모델링

초록

As the needs for flexible power generation increase, gas turbines tend to experience more rapid changes in operating conditions because they usually have to cope with variable power demands in power grids. Various commercial and non-commercial simulation programs have been used to predict the performance of gas turbines. Since simulation functions and capabilities are different among those programs, it is important to select an appropriate one according to user’s purposes. In this study, an in-house program and a commercial program (Flownex) were used for the purpose of predicting operations of actual gas turbines more accurately. Common component and control models were applied to both programs to simulate the operation of an F-class gas turbine and the results were compared with actual operation data. Very accurate simulations were observed for both programs. Based on the confirmed validity for steady-state simulations, each program will be further improved for dynamic simulations by complementing each other.
