GE公司PG9171E型燃气轮机事故处理

1、GE公司PG9171E型燃气轮机事故处理 事故处理的一般要求应尽量限制事故的发展,防止事故的扩大,解除人身及设备的危险。迅速解除主设备的危险，维持非事故设备的正常运行。及时保存事故发生时，停机前后的运行数据，以及曲线记录。事故发生时主要现象，操作要及时汇报班、值长、并做好记录。发生重大事故应立即汇报有关领导。事故发生后应根据表计，保护，信号及自动装置动作情况作全面分析，作出处理。事故停机过程中应着重监视排气温度，滑油回油温度，轮间温度，以及各轴承振动和机组本体有无摩擦声。事故停机后应保证控制系统的直流电源供给。保证冷却水继续工作，压力正常。保证各加热器在自动位，燃机进口导叶在关闭位，燃烧室确已

2、熄火。10保证辅助滑油泵或事故滑油泵投入工作，压力正常，燃机转速低于900RPM时保证交流或直流顶轴油泵正常投入，转速到零后保证交流或直流盘车正常投入如因机组轴系故障引发的跳机事故，转速到零后，未对旋转部件进行检查之前不允许盘车。若机组因火灾保护跳机，在CO2释放期间严禁运行人员进入室内，并应保持室门关闭，将88BT1/2，88VG1/2，88TK1/2开关刀闸断开。机组保护遮断停机后，再次开机之前必需确认是否为误动作，如为误动作，应采取相应措施，处理误动作故障。紧急停机时，应先确认报警，消除音响，将报警信号保存在计算机中，未查明原因未排除故障时，不能复归报警，不能重新启动机组。14紧急停机后

3、，所有有关数据必须收齐整理好汇同事故报告交到部里。 机组的紧急停运出现下列情况时机组必须紧急停运1.自动紧急停运：自动紧急停运的依据：机组超速保护动作；机组超振保护动作；机组排气超温保护动作；A.B.C.D或E.F.G.H四个火焰探测器中的任意三个熄火机组滑油母管压力底于跳机值机组滑油母管温度跳机值机组95%SPD以下出现“防喘阀位置故障”报警；机组的燃机间,辅机间,发电机间温度超过316,排气室温度超过516或发生明火,机组火灾保护动作.机组排气温差大遮断保护动作；主变压器差动保护继电器动作发电机差动保护动作；DLN小室通风道，轮机室，轮机通风道中每组二个以上可燃气体探测浓度8%,或每组一个

4、故障，一个可燃气体探测浓度8%,燃气小间失去通风报警保护动作；机组燃烧模式切换时出现“DLN系统故障”报警；机组运行时出现“燃气速比阀故障遮断”报警；机组运行时出现“燃气切换阀门故障”报警；2.手动紧急停运:（1）手动紧急停运依据:机组发生故障,自动紧停保护触动；机组运行中任一轴承断油、冒烟；机组内转动部件有明显的金属撞击声,机组振动突然明显的增大;机组发生喘振;滑油系统大量泄油；天然气管路爆管大量泄漏天然气；发电机励磁机冒烟；发电机出线电缆头、开关或避雷器爆炸；发电机电压互感器或电流互感器冒烟；天然气系统起火,不能及时扑灭;发“天然气压力低”报警，控制室伴有强烈振动感，有功负荷大幅摆动，且这

5、三种现象同时出现时；发生的故障可能严重危及人身设备安全的情况。（2）手动紧急停运操作: 按下轮控盘上或辅机间内“EMERGENCY STOP”按钮或在四控按下紧急停机按钮，发出紧急停机信号,机组紧急停机。 机组紧急停运后，立即确认机组已正常执行紧急停机令： 1)主变出口开关2203开关跳闸，发电机有功、无功、电压、电流到零发电机灭磁，励磁电压、电流到零2)天然气速断阀关闭，天然气流量到零3)燃机熄火，#A、#B、#C、#D、#E、#F、#G、#H火焰灭4)机组进入惰走5)MK-e CRT主画面状态显示“TRIP”，发相应的报警(3)紧急停机后的操作:1将以下内容汇报值长：机组因何种原因紧急停机

6、；发电机电气保护盘上保护继电器动作情况；MK-e的报警信息内容。打印报警信息及历史跳闸记录如滑油泵出口油管压力低于3.103bar辅助滑油泵88QA-1应自动投入运行,滑油母管出口压力低于跳机值,应急滑油泵88QE-1自动投运机组转速下降到50%时,查顶轴油泵88QB-1投运查机组的盘车是否正常,88TG-1是否正常工作值长确认同意后，复归手动停机按钮、机组保护、报警，对机组进行冷拖，确认机组升速并稳定在25%SPD左右，约20分钟后发停机令，冷拖时全面检查机组。约20分钟后经值长同意后在MK-VI“Control Start-up”画面点击“STOP”靶标，点击“cooldown”结束冷拖。

7、机组减速到正常转速投入盘车冷拖结束后等待值长命令进行下一步操作，并做好事故报告。第三节 Mark VIe 中英文报警清单序号报警内容1WheelSpace.L30WSA1_ALM WHEELSPACE TEMP DIFFERENTIAL HIGH轮间温差高2WheelSpace.L30LTA_ALM LOAD TUNNEL TEMPERATURE HIGH - AUTO UNLOAD负荷间涡壳温度高自动降负荷3WheelSpace.L30WSA2_ALM WHEELSPACE TEMPERATURE HIGH轮间温度高4WheelSpace.L94LTH_ALM LOAD TUNNEL TEM
