The control systems of thermal power generation units with large-capacity and high-parameters are becoming increasingly more complicated and numerous

in order to easily realize unified manage momt of a whole thermal power plant

and to effectively enhance the economic benefits of the power plant

the integrated super-visory and control system of a thermal power plant seems to be particularly important.Along with strengthening and perfecting the functions of computer technology

DCS and desulfuration control system(FGD-DCS)

the management and control modes of present control system of units adopted commonly the DCS/DEH mode(including ECS section) and its auxiliary systems become more numerous and various

hence

an approach to the scheme of realizing integrated supervisory and control in thermal power plants has been carried out.
