摘　　要：通过对山西某新建350 MW超临界循环流化床机组辅机故障减负荷(RB)功能试验分析,介绍了RB功能控制策略、试验过程及存在问题,再经过控制优化提出改进方案并实施,确保机组在生产试运中发生RB后协调控制系统及其他自动控制系统的调节性能达到最佳,从而实现机组在此特定工况下能够安全、经济、平稳运转。Through the analysis of the fault load reduction(RB)function test of the auxiliary unit of a newly built 350MW supercritical circulating fluidized bed(CFB)unit in Shanxi Province,the control strategy,test process and existing problems of RB function are briefly introduced.After control optimization,the improvement plan is proposed and implemented.To ensure that the unit in the production trial run after RB coordinated control system(CCS)and other automatic control system to achieve the best performance,so as to achieve the unit in this particular working condition can be safe,economic,stable operation.

关 键 词：350MW超临界CFB机组 RB功能 控制策略 协调控制
