Study of the Condensing Unit Operating Modes of the Power Unit of a 300 MW Thermal Power Plant

Abstract

The article presents the results of the analysis of the operation main modes of the condenser for a 300 MW power unit capacity of a K-300-240-2 KhTGZ turbine. The article presents graphs of the dependence of steam consumption at power consumption in the condenser and heating, the change in the final enthalpy at the pressure flow in the condenser, etc. Calculation of the condenser thermal balance of the power unit was carried out on the basis of the power plants classical calculation of thermal circuits. Based on the obtained results, a mathematical model was developed that can use in the development of a prototype hardware complex for controlling the rotation of the blades, taking into account the correction for changes in the vacuum characteristics and load characteristics of the power unit.
