Testing of the Black Start unit BLM902 was discontinued at 1135 and the EGS electrical plant was re- aligned following the EGS electrical operating procedures at 1200.At this time the EGS electrical plant was restored and GSU 903,MV Bus C and D,480V bus 901 Bus B and the 480V MCC's re-energized with the four operating units continuing to provide power through GSU 901.Under the normal plant MV bus configuration generating units are aligned so that there is at least one unit(s)providing power through each GSU. At 1313 an EGS operating technician informed the Control Room operating technician that he thought that BFA 901 Bus A breaker E2 had been closed rather than E11 prior to the start of the that mornings shutdown of the Black Start test.The Control room operator using the DCS (Distributed Control system) selected BFA901-E1 to open.BFA901-E2 was also open at this time.When BFA901-E1 opened,LV Bus BFA901 A was de-energized and all auxiliary power fed from this bus also lost power which included all the SEH auxiliary power panels shutting down the fuel supply pumps and the radiator cooling fan Variable speed controllers.SEH DG units 1,2,3 and 4 shut down on low fuel oil pressure. The operator realized his mistake and reclosed BFA901-E1.Once the engine auxiliaries were reset,DG units were restarted.The first unit to come on-line was DG unit 7 approximately 10 minutes after the plant trip followed by 10,5 and finally 6. Root Cause Analysis: Operator switching error caused plant shutdown when the incorrect electrical breaker was opened via the DCS system.The operator failed to verify the electrical plant arrangement and did not follow the EGS electrical procedures when conducting system switching. Remediation measures and recommendations The Control room operating technician was relieved from the lead Operator position on the control board by the outside operating technician. The Control room technician was placed under further electrical system and DCS system training and duties will not include taking the lead Operator position on the control board until they have completed the training and have been duly checked off by the Operations Supervisor.
