The Type Selection Analysis And Application Planning Of FCS About Shenhua Shengli Plant

Field bus control system has broken the structure form of the traditional computer control system that equipment is connecting with the field one-to-one in accordance with the requirements of the control loop. The control module and a variety of input and output modules of the original traditional distributed control system (DCS) are installed or embedded in the field equipment in the form of distribution.These intelligent equipments, devices and instrument are connected with main equipment computer system to constitute a local computer control network system, make the control system can not rely on the computer or module in the control room..The paper, combined with the example of the Shenhua Victory Supercritical Power Plant Units(2×660MW), thoroughly analyzed the configuration selection of main and auxiliary control system of large-scale thermal power units, which is realized by using field bus control technology .
