(PDF) Report on "Steam Power Plant" | Saddam Hussain Sohag
In first stage (the high-pressure turbine), steam is expanded isentropically to an intermediate pressure and sent back to the boiler where it is reheated at constant pressure, usually to the inlet temperature of the first turbine stage. Steam then expands isentropically in the second stage (low-pressure turbine) to the condenser pressure.

Flatness‐based control for steam‐turbine power generation
Apr 07, 2021 · 1 INTRODUCTION. In parallel to renewable energy systems deployment during the last years, a large part of the produced electric power still comes from conventional thermal power stations, and particularly from steam-turbine power plants or from power stations of combined cycle [1-7].For this reason steam turbines (and also gas turbines) are widely used for providing the mechanical power and

Classification of Turbines – Steam - Nuclear Power
Condensing steam turbines are most commonly found in thermal power plants. In a condensing steam turbine, the maximum amount of energy is extracted from the steam, because there is very high enthalpy difference between the initial (e.g. 6MPa; 275°C; x = 1) and final (e.g. 0.008MPa; 41.5°C; x = 0.9) conditions of steam.This is achieved by passing the exhaust steam into a condenser (called a
