  • Method and device for controlling the temperature of steam for a steam power plant
    Patent number: 9500361
    Abstract: A method for controlling the temperatures of steam for a steam power plant is provided. A state controller, in order to output a desired steam temperature as a controlled variable, feeds back several steam states in a superheater for superheating steam using a monitor, which calculates the steam states, and the desired steam temperature is forwarded to a further controller for controlling the temperature. In order to achieve a stable and accurate control of the steam temperature, it is proposed that the state controller be a linear quadratic controller.

  • Method and device for regulating the production of steam in a steam plant
    Publication number: 20130133751
    Abstract: A method for regulating the production of steam from feed water in an evaporator of a steam plant is provided. A state regulator calculates a plurality of states of a medium in the evaporator by means of an observer and, on the basis thereof, determines a feed water mass flow rate as a regulating variable. In order to obtain a stable and precise regulation of the temperature of the steam, the state regulator is a linear-quadratic regulator.
