| Abstract: |
| The status quo of DCS(Distributed Control System)in power plant is introduced.Accor-ding to the practical operating conditions of DCS and combined with the considerations of equip-ment purchase and technical support,the necessity of power plant DCS reconstruction is discussed.The structure of DCS is introduced and a reconstruction scheme is presented,in which the quantity extension of automatic processing unit,communication processor and superordinate computer and the upgrading of hardware and software are applied to improve the inner performance of DCS.With the practical reconstructions as examples,the implementation steps and the effectiveness of extension and upgrading are expounded,which verifies that the DCS reconstruction improves the system availability and operation efficiency. |
