Abstract : The structure and design essentials to this electric station using remain heat of the
distributed control system is introduced in this paper. The system is composed of supervise
and control layer, process control layer with a few field meters and control instruments. The
DCS can realize supervising of the technology process, automatic controlling of two boilers
and a steam turbine–generator group with assist equipments. The control tactics of
important loop about cyclic mobile layer boiler is described in detail.
