Start and load a gas turbine and heat recovery steam generator after a trip
You are the Unit Controller on panel B, afternoon shift.
What has happened
GT2 tripped at 2:22 pm on 5 September on high exhaust temperature spread, taking the station from 310 to 165 megawatts. The instrument crew checked the can 7 thermocouple loop and found a loose terminal. The market operator has asked when the unit will be back and the Operations Manager wants it restarted as a hot start under the procedure with every check done. There is an open permit on the GT1 fuel gas skid, the ammonia dosing system on HRSG2 is in service and the afternoon peak begins at 5:00 pm. Leanne Boschetti also wants to know what the log entry from the earlier restart failed to record.
Deliverables
- Pre-start checklist
- Operations Log entries for the start
- Note on the earlier log entry gaps
- Completed shift handover report

Evidence guide
Evidence must show the pre-start checks in the procedure order, awareness that open permits determine whether a unit can start, correct parameters watched during the start (vibration, exhaust spread, bearing temperatures), the hot warm up rate and drum level control, and a log entry that records start type, times, holds and load. The handover must list open permits and the standing instruction.
