1. SCOPE OF WORK

Furnish and deliver protective relays, revenue meters, auxiliary & automation controllers, computer and

network equipment for the protection, control & annunciation systems upgrades at McNary Powerhouse.

The overall scope of this contract in relation to the SEL protection and control equipment is to replace and

upgrade the existing protection and control (P&C) equipment for the main unit generators and GSU

transformers. The equipment will facilitate new annunciation and sequential event recording (SER)

systems. It will also be integrated with new equipment back to the communications and control room for

GDACS control and monitoring.

2. GENERAL

The SEL (P&C) equipment will be used for upgrading main unit generator and GSU transformer protection

and control systems at McNary Powerhouse. The SEL equipment will replace the existing SEL equipment

and be installed into new S-boards under a separate construction contract. The S-boards are being replaced,

so new protective relaying equipment is required. The SEL real time automation controller (RTAC) and

SEL Axion (auxiliary controller) will be used for collecting alarms for the new annunciation/SER system

and are compatible with new human machine interfaces (HMI) and networking equipment for GDACS. A

separate annunciation panel is needed in the control room to provide hardwired door security switches to

the control room for S-boards and related equipment.
