چکیده:

Gas turbine in combined cycle power plant has ability for changing operation condition rapidly and more frequently. So its useful life is lesser than steam turbine. Gas turbine controller must increase its useful life because of high expenditure of gas turbine constructing. Damage mitigating control or life extend control, is to design the controller to achieved better trade off between structural durability and dynamic performance in a system. In this paper designing a life extending predictive controller (LEPC) in regulatory and supervisory level, to obtain a good trade off between the life of gas turbine system and control system performance. Main objective is decrease accumulated damage using predictive control capability in constraint covering in control system structure LEPC apply GILAN combined cycle power plant gas turbine simulator then compared in supervisory and regulatory level. Simulation results show that it reduced accumulated damage with loss in system performance.
