First-principle component models for control system simulation of MHD-steam plants
Abstract
The first-principle, lumped-parameter subsystem models for the CNCD unit, typical steam-water path units, the boiler feed pump, the steam drum, steam turbines, the air compressor, and the spray attemperator are discussed. The models can predict time-varying changes in combustion gas temperature and enthalpy, and temperature within each major component of the combined-cycle system. Methods of connecting the component models for the computer simulation of a typical MHD-steam cycle are considered along with relationships between control variables and system state variables. It is concluded that alternative coordinated control strategies can be imbedded in the simulation to assist in the specification of overall control topology and controller parameters.
