摘要
DCS计算机自动控制系统是火力发电厂自动发电控制的核心,其正常、稳定工作与否直接关系到整个发电机组的安全、稳定、经济运行。当DCS系统运行年限不断增加,将会出现设备故障、老化情况日益严重,无法适应机组自动化监视和控制要求的情况,因此需要对DCS系统进行升级改造。本文就300MW机组DCS系统升级改造实例进行介绍。
DCS computer automatic control system is the core of automatic generation control in thermal power plant,its normal and stable operation is directly related to the safety,stability and economic operation of the whole generating set.When the operation life of DCS system is increasing,the equipment failure and aging will become more and more serious,which cannot meet the requirements of automatic monitoring and control of units.Therefore,it is necessary to upgrade the DCS system.This paper introduced the upgrading of DCS system of 300MW unit.
