STEAM THERMOMETER AND ITS GENERATOR STEAM TEAMPERATURE CONTROL METHOD BY NONLINEAR PROCESS MODELING

摘要

The disclosed invention relates to a steam temperature controller by nonlinear process modeling and a method for controlling steam temperature of a power plant using the same. The present invention, by optimizing the steam temperature of the power plant, the final superheater can determine the steam injection amount by a non-linear control type, so that the steam temperature of the power plant can be stably maintained even in the normal mode as well as abnormal mode, so that the power generation of the boiler, turbine, etc. In addition to eliminating the adverse effects on the installation, there is an effect to improve the power generation efficiency.
