| 摘 要： | 采用“二拖一”运行方式的联合循环机组,当一台余热锅炉出现故障而跳炉时,如不及时处理会引起汽轮机误跳,进而使另一台余热锅炉跳炉。这几年,镇海联合循环机组此类事故频发,影响了机组的稳定运行。本文介绍该厂针对此类汽轮机误跳现象,在确保主设备安全的前提下,对锅炉部分保护逻辑进行了修改,以减少汽轮机误跳几率,确保汽轮机稳定运行。

| Abstract: | When the combined cycle unit is 'two drive one'operating mode,the steam turbine will trip,if it is not deal with in time,when one of two HRSG trips for some reason,and the other HRSG will trip too.It happens in Zhenhai combined cycle unit several times in these years,and it affects the unit operating badly.This article introduces the ways to decrease the frequency of trips of the steam turbine by the protection logic of HRSG in order to stabilize the operation of the steam turbine. |
