摘要

介绍华能福州电厂二期英国三井巴布科克 2× 35 0MW机组锅炉所采用的西门子TXP分散控制系统的中负压控制系统的设计特点

包括 :(1)调节器输入偏差信号及送风量前馈信号 ;(2 )对调节器输入信号波动的处理 ;(3)单 /双机增益的调整 ;(4 )平衡电路 ;(5 )炉内防爆保护 ;(6 )引风机高、低速切换。该控制系统已运行了 5年多

在锅炉起停、总燃料跳闸 (MFT)、辅机故障减负荷 (RB)动作、高低速切换等工况下调节稳定

性能可靠

Abstract

The design features of negative pressure control system in Siemens made TXP distributed control system used for 2×300 MW units imported from UK in the secondphase project of Huaneng Fuzhou Power Plant have been briefly presented

including:（1） input deviation signal of the regulator and feedforward signal of forced draft air flow; （2） treatment of input signal fluctuation for the regulator; （3） adjustment of gain for single and double units; （4） balanced circuit; （5）explosive protection in the furnace; （6） highand lowspeed changing for induced draft fan. The said control system has been put into operation and reliable performace under operating conditions

such as startup and shutdown of the boiler

main fuel trip

run back actuation

highand lowspeed switching etc..
