TRT发电装置运行控制龚运鹏;井洋【摘要】介绍了天钢TRT发电装置的运行控制情况。
TRT发电装置的启动和功率的升、降,正常及非正常停机均采用先进PLC控制系统,保证了系统的稳定性,实现了发电效益的最大化。
同时,为了避免造成设备事故,采用PLC联锁保护系统,保证了TRT发电装置设备的安全运行。
%The paper introduces the control over the running of Tiangang Top Gas Recovery Turbine Unit (TRT). Adopting for the start, power going up and down and normal and abnormal stoppage of TRT power generation unit, PLC control system ensured the stability of the system and realized the maximization of power generation benefit. Meanwhile PLC interlock protection system was adopted to avoid equipment incident and ensure the safe running of TRT power generation unit.【期刊名称】《天津冶金》【年(卷),期】2015(000)0z1【总页数】4页(P40-43)【关键词】高炉煤气;余压透平发电装置;PLC控制;联锁保护【作者】龚运鹏;井洋【作者单位】天津钢铁集团有限公司信息化部,天津300301;天津钢铁集团有限公司信息化部,天津300301【正文语种】中文Abstract The paperintroduces the controloverthe running ofTiangang Top Gas Recovery Turbine Unit (TRT).Adopting forthe start,powergoing up and down and normaland abnormalstoppage ofTRT power generation unit,PLC controlsystem ensured thestabilityofthesystem and realized themaximization ofpower generation benefit.Meanwhile PLC interlock protection system wasadopted to avoid equipmentincidentand ensurethesaferunningofTRT powergeneration unit.Key words blastfurnacegas;Top GasRecovery Turbine Unit;PLCcontrol;interlock protection天津钢铁集团有限公司所属动力厂共有2台TRT发电机,均为陕西鼓风机有限公司产品,全部坐落于高炉区域,由燃气作业区管理,其中1台TRT发电机对应2 000 m3高炉,发电负荷107W,另1台TRT发电机对应3 200 m3高炉,发电负荷1.5伊107W,发电量通过升压变压器上传到22万变电站,在进行统一用电负荷分配。
