Hungry Horse Excitation System Replacement

Hungry Horse Excitation System Replacement, Hungry Horse Powerplant, Montana

The Columbia-Pacific Northwest (CPN) Regional Office of the U.S. Bureau of Reclamation has a requirement for a construction contract to design, furnish, install, test and commission replacement of existing excitation systems with fully static digital excitation systems for Generator Units 1, 2, 3, and 4 in the powerplant. This project is located at Hungry Horse Powerplant approximately 4 miles south of Hungry Horse, Montana, in Flathead County.

The Principal Components of Work:

A. Design, furnish, install, test and commission replacement of existing excitation systems with fully static digital excitation systems for Generator Units 1, 2, 3, and 4 in the powerplant. Work includes:
1. Remove and dispose of the following equipment:
a. Existing excitation systems, field breakers, power potential transformers (PPTs), metal enclosed bus, and associated equipment.
b. Existing interface cables and conductors.
c. Control and annunciation cables associated with existing excitation systems.

2. Furnish and Install:
a. Fully static digital excitation systems.
b. 15kV metal-enclosed buses from generator main buses to excitation PPTs and PT cubicles.
c. 635V AC metal-enclosed bus.
d. 800V DC metal-enclosed bus.
e. Provide PPTs, excitation supply low voltage power circuit breakers, instrument transformers, instrumentation cable and conductors, DC connection to machine field and other associated equipment.

B. Modify generator terminal tap location and unit protection cabinets.

C. Electrically isolate existing rotating DC exciters, which are to remain in place and remove the DC machine stator poles.

D. Provide control and power cable, wire, and associated conduits or cable trays for power, control, protection and alarm circuits. Terminate all cabling required for turnkey installation.

E. Furnish parts required for operational continuity as required in applicable sections.

F. Furnish drawings and data in Government format.
1. Includes revision to Government drawings external to excitation system to address requirements of turnkey installation.

G. Furnish and install conduit for power circuits where existing conduit cannot be used.

H. Use the same manufacturer and model for each component with the same function and capacity for all four units.

I. Factory and field testing of new excitation systems, PPTs and associated equipment.

J. Train Government personnel in operation and maintenance of new excitation.
