Summary Scope of Work (SOW):

Chief Joseph Dam is located on the Columbia River and houses 27 hydroelectric generators with a total generating capacity of 2620 MW, the largest in the USACE hydropower fleet. The 480V station service system provides power for auxiliary equipment required to run each generating unit properly including governor oil pumps and turbine bearing oil pumps. Each unit has an associated switchgear and/or motor control center (MCC) that is used to supply their respective auxiliary loads. Since the generators were installed at different times, the power distribution configurations vary depending on the units under observation. Unit 1- 16 auxiliary loads are fed from motor control centers SU1-SU4 installed in the 1950’s. The configurations are described as follows for SU1-4:

• SU1 – Units 1-4

• SU2 – Units 5-8

• SU3 – Units 9-12

• SU4 – Units 13-16

The above-mentioned equipment is original to the plant and is outdated, meaning replacement parts are difficult to obtain. SU1-SU4 have interconnections to provide a backfeed for each center, but they do not provide full redundancy, meaning multiple units could go offline if a fault occurs. Arc flash incident energy is high on equipment buses, and mitigation techniques (such as maintenance modes) are nonexistent.

The purpose of the project is to replace the existing switchgear, MCCs and associated transformers. The new equipment will include modern circuit breakers and improved personnel safety risks. A new SCADA system will enable operation of power circuit breakers and status monitoring (open, closed, trip) of main and tie breakers for SU1-SU4 from the Control Room HMI. Local control panels will provide the similar functionality for all power circuit breakers at the switchgear/MCCs, but outside of the defined arc flash boundary. All new 4160/480 V service transformers will be delta-wye with secondary windings that have high resistance grounding (HRG) systems equipped with alarms in case of single line to ground faults on the 480V side. Two service transformers will be provided for SU1-4 to ensure the equipment remains operational in case one transformer is offline.

The 480V station service upgrade scope of work includes:

SU1-SU4 Replacement

Replacement of SU1-SU4 motor control centers with electrically operated main and tie air circuit breakers with automatic transfer scheme and redundant 500 kVA transformer in different locations (one close coupled)

Provision of additional feeders from SP switchgear spare breakers and modification to existing digital relays.

Installation of standalone SCADA system and remote control/status HMI in control room.

Separation of 120 VAC and 125 VDC circuits will be accomplished by relocating lighting panels and TRU lighting transformers in existing equipment to wall-mounted locations

Replacement of downstream 480V motor control centers CQ13, CQ23, CQ33, CQ43 that service GSU transformer and unit auxiliary loads

Local control panel and HMI that will provide control and indication status of each main/tie breaker for each SU, and remote control from HMI in control room.
