INTEGRATED CONTROL-SYSTEM FOR A TURBOGENERATOR

The paper describes the development of a linear time-invaviant control system for a turbogenerator in a power system. The contxoller is based on a discrete seventhorder state-space model of the turbogenerator, rising actual values of state variables, rather than deviations from specified reference levels, and is augmented to incorporate output integral feedback. It is tested on a 13th-order non-linear turbogenerator model, which includes hard constraints on excitation and turbine valving. Results are presented which illustrate the ability of the controller to function satisfactorily during both steady-state and transient conditions, and to accept changes of system configuration and operating point, while maintaining full control action. A secondary controller has been designed to bring the generator to a desired new operating point. © 1979 Taylor & Francis Group, LLC.
