摘要

为了提高亚临界机组在辅机故障减负荷(RB)、给煤机断煤、机组背压快速升高、高压加热器退出等异常工况下控制系统的自动投入率

对控制系统执行机构指令与反馈偏差大、设定值与测量值偏差大、冗余测量值偏差大、将自动控制方式切换至手动控制方式的条件进行屏蔽等优化。优化后控制系统的自动投入率得到了进一步提高

保证了机组安全、稳定运行。

Abstract

In order to enhance the putting-into-operation rate of automatic control systems under abnormal operating conditions of subcritical units

such as units in run-back(RB) process

coal stoppage in coal feeders

rapid increase of back pressure in units

and high-pressure heater being out of service etc.

optimization of control systems

such as screening large deviation between commands and feedback of the actuator

large deviation between set value and measured value

switching automatically to manual control mode because of large deviation between redundant and measured values etc.

have been carried out.After optimization

the putting-into-operation rate of automatic control systems has been further enhanced

ensuring safe and stable operation of units.
