NUMERICAL ANALYSIS OF THE STEAM TURBINE PERFORMANCE IN POWER STATION WITH A LOW POWER CYCLE

Abstract

In this paper, an analysis of the temperature and quantity balance of the thermal power plant for the Al-Dura (K-160-13.34-0.0068) station was first studied and used for reference. This work describes a possible way to build a simulation model of the most important parts of power plant Al-Dura (K-160-13.34-0.0068). The Cycle-Tempo and MATLAB/Simulink packages are used to model the energetic and exergetic analysis of the power plant. MATLAB/Simulink software was used to simulate the behaviour of a Steam turbine with high-pressure, intermediate-pressure, and low-pressure steam, with a load response in a stable circumstance over a range of 50% to 100%. The model is based on Stodol's law and simulates the pressure and enthalpy alongside the dissimilar turbine phases and the vapor and water extraction. The effect of the vapor and water extraction on the turbine is also elucidated. Areas of essential energy loss and exergy decimation will be resolved. The impact of changing the power plant load on the exergy analysis is determined. The response of suggested purposes to estimate these vapor properties is compared with standard data and showed high accuracy (the modelling error is less than 0.01%).
