提高发电厂辅助车间辅控网可靠性的策略研究

STUDY ON STRATEGY FOR ENHANCING THE RELIABILITY OF AUXILIARY CONTROL NETWORKS IN AUXILIARY WORKSHOPS OF POWER PLANT

总结大唐王滩发电公司辅助车间辅控网设计、实施及完善的方案和经验得出:(1)辅控网设计应统一规划;(2)输煤程控系统主站和各远程站间应采用光纤联接;(3)采取折衷方案解决测点较多的系统负荷偏重的问题;(4)改变干除灰及脱硫控制系统的配置,以解决通讯超时中断的问题。

The scheme and experience of designing, implementing, and perfecting the auxiliary control networks in auxiliary workshops of Wangtan Power Generation Co Ltd have been summarized as follows： （1）the design of auxiliary control networks should have a unified plan; （2）in programmed control system of coal handling,optical fibre connection must be adopted between main station and each remote station; （3）adopting compromise scheme for solving the problem of heavy load in system boasting more measuring points; （4） changing configuration of control systems for dry ash -handling, and for desulphurization, solving the problem of over- time interruption in communication.
