Application of Sequential Control Based on Device Code Strategy in 1000MW Power Plant
2013
A thermal power plant, where there are hundred of equipments, and many of them are usually controlled by sequential control system (SCS),which is a part of Distributed control system (DCS). For a relatively independent process system, it can be controlled by some of steps, generally, we use the traditional sequential control module supplied by DCS to construct the control logic. This article introduces a brand new control strategy -- the Sequential Control based on Device Code (SCDC). This control method can be used in the occasion of a large number of equipments to be controlled, with the advantage of clear structure, easy maintenance etc.. This method can be widely used in many technological control fields.
