Power plants generate electrical power by using fuels like coal, oil or natural gas. Fuel burned in the boiler to heats water to generate steam. The steam is then heated to a superheated state in the superheater. This superheated steam is used to rotate the turbine which powers the generator. Electrical energy is generated when the generator windings rotate in a strong magnetic field. After the steam leaves the turbine it is cooled to its liquid state in the condenser. The liquid is pressurized by the pump prior to going back to the boiler. This simple power plant is called (steam power plant). This cycle has a problem represent through a steam leaves the turbine, it is typically wet. The presence of water causes erosion of the turbine blades at high speed, gradually decreasing the life of turbine blades and efficiency of the turbine. That's leading to damage of turbine then shut-off plant. So, a simulation process of steam power plant done using (Hysys v.3.2) to improve the performance of plant also increasing efficiency through prevent erosion occurs and decreasing heat loses by condenser. Good results obtained by simulation process, in which overall efficiency of the plant increased from 24.57% to 28.1%, thermal efficiency increase from 24.59% to 28.1% that leads to decrease a heat loses from cycle, also increase the output rate of electrical power produced to about 15%. The results obtained from study can be applied in field where it can improve the performance of steam power plant especially in the oil industry by increasing the rate of electric power can also take advantage of waste heat in the production of distilled water.
