Abstract: The thesis describes a steam power plant simulator which has been developed using the MATLAB code. The simulation is important to study the behavior of the steam power plant system by means of a model, and the results obtained allow us to consider many different design possibilities as well as varieties operating conditions. Therefore, different designs may be evaluated so that an acceptable design can be chosen and safe levels may be established for the operating conditions. These results are also used for optimization of the plant. The basic considerations in the development of a mathematical model are first presented in the thesis, followed by a discussion of simulation of a steam power plant. Conservation equations and characteristic curves are used to model the component of the steam power plant. From these mathematical model equations, the component modules are developed using MATLAB code. Output parameters are obtained from input data to the component modules. The STEAM_POWER_PLANT_SIMULATION program is used to simulate the power plant system. In the program there are two main solvers. These are: the turbine-heater solver and boiler solver. The turbine-heater solver consists of the turbine and feed water heaters including the pumps and the condenser. The boiler solver has its own residue generator function and Jacobean generator function and then Newton-Raphson technique is used to solve a set of nonlinear algebraic equations.
