The upgrade will improve reliability and align the projects with the Regional Station Service Design Philosophy. Upgrades to the DC Systems include replacement of the DC system panels, preferred AC panels, chargers, battery boards and installation of load bank for performing discharge tests on the batteries in accordance with IEEE and the NERC/WECC requirements. This project will also replace the 480-Volt Low Voltage Station Service Switchgear including breakers and transformers for SQ0, SQ1; transformers for SQ2; 480-Volt Motor Control Centers and Panelboards FCQ1, CQ1 and CQ1.1, CQ01 through CQ05, and SH and SU Switchgear. 480V Switchgears & panelboards a) Replacement of two (2) 480V switchgear, two (2) 480V transformers; ten (10) motor control centers, and four (4) panelboards. b) All cables associated with the switchgear, MCC and panelboards will be replaced. c) All new switchgears, MCCs and panelboards to be provided must be from the same manufacturer. d) Conversion of twelve (12) 4160V governor oil pumps to 480V pumps. e) Installation of local control cabinets for each SQ (including SQ2) which will provide local hardwired controls and indication for 480V breakers. Cabinets will also house PLC I/O modules which will be integrated into the existing plant All-In-One (a.k.a. stand-alone) system. PLC inputs will include, but not be limited to, breaker status and racked out contacts, protective device contacts, and other relevant annunciation points. PLC outputs will provide remote SQ breaker trip/close controls from All-In-One HMI screens in the control room. Existing, generic hardwired SQ alarms will be replaced in kind to the alarm control panel (code call) in the control room. PLC inputs will also be provided for the new DC and preferred AC system. These input modules will be incorporated into the All-In-One system. Generic hardwired alarms for new DC and preferred AC system will be added to alarm control panel. DC & Preferred AC System a) All DC and Preferred AC system switchboards and panelboards will be replaced. b) All cables associated with the switchboards and panelboards will be replaced. c) All battery chargers, and battery monitoring system will be replaced. d) Installation of a permanent load bank for battery testing. e) Provide local annunciation at the SB boards for alarms. Annunciation points will connect to the control room all-in one system. f) Relocate the battery room lights to the aisle way instead of directly above the battery. g) Replacement of the door to battery room. New door will have 1-hour fire rating, be open from the inside and be equipped with listed panic hardware. h) Install new smoke sensors and hydrogen detector in the battery room. Mechanical a) Ventilation inlet will be dropped to a level below the top of the battery cells. b) Eye wash/Shower system will have an on demand, electric heater added (Tepid Water System). A reservoir will have to be added to the drain lines or shower unit will have to have its own reservoir attached.
