The power station experienced a lightning strike(GE 9FA). A number of alarms initiated. On the Generator Excitation DCS page (Mark VI) on the Control Selection this transferred from Master 1 to Master 2. Volts/Hz alarm initiated. Backup Exhaust Reference Temperature initiated The load increased immediately from 373MW to 402MW.
I am aware of the overfluxing alarm but could someone help me as to why the Backup Exhaust Reference Temperature alarm initiated and what is the significance of the Control selection transferring from Master 1 to Master 2? Is it safe to press a Reset Transfer?
