Generally, the main components of a power plant are a gas turbine, a boiler and a steam turbine. Factors such as high pressure and temperatures affect the operational conditions and efficiency of large complex systems such as the power generation plants. Hence, it is desirable that the power plant be properly controlled in order to achieve optimum performance. Thus, a state space model is proposed. The model is mathematically convenient structure for control design and analysis of multivariable dynamic system. In addition, this approach is based on time domain analysis and synthesis using state variables. This paper focuses on the development of a state space model for a reheater system, which is one of the subsystems in the boiler of a power plant. The structural properties of the system are also analyzed. Thus, the possibility of integrating uncertainties and applying other mathematical techniques in modeling the system can be further explored.
