Abstract:After analyzing the characteristic of the water treatment in 300MW boiler-turbine- generator, the single input multiple output (SIMO) models for dosing system and pH control dosing system and low phosphate treatment system are developed. Based on these SIMO models an intelligent variable structure and redundant control method is proposed. As an example, in the end of the paper a distributed control system for boiler water treatment is introduced.
Keywords:Water treatment  Model  Electric shock  Add medicine  Frequency converter  Boiler
