Design and implementation of cascade control structure for superheated steam temperature control

Popis výsledku v původním jazyce

This paper deals with design and implementation of control system for superheated steam temperature control of high pressure part in the small biomass power plant. It describes the steam superheating technology, the actual state and the way how to realize the improvement in this control. The designed control algorithm represents standard cascade control with two PI controllers with some additions like feed forward control applied on measured disturbance, compensation of level change in steam production and compensation of valve nonlinearity. The important fact, in terms of control algorithms implementation, is verification of control system properties during the change of process dynamics (load level step) and response to disturbances. The Simulink model was used for the simulation experiment. Some significant simulation results from simulation tests and from the real time tests are presented. The improved control structure was implemented to the PLC and tested on the plant. Additionally a comfortable and user-friendly interface for controller's parameterization and compensation of valve nonlinearity was created. The response of the new control system and the original control system response are compared.
