Design, manufacture, factory test and deliver two (2) 75,000/100,000 kVA, 161x69kV GrdY/13.2 kV Delta, Class ONAN/ONAF cooling, with nitrogen blanket oil preservation systems, three-phase generation step up (GSU) power transformers and accessories complete from the manufacturing facility to the Old Hickory Power Plant, Hendersonville, TN.

CONTRACT SCOPE

PROJECT BACKGROUND

Located at Mile 216.2 on the Cumberland River and is approximately 20 miles northeast of Nashville, TN.

The project was completed for full beneficial use in December 1957 with the placement of the final hydropower unit in operation.

Total of 4 generating units with each as commissioned rating of 31.25MVA and 115% overload capacity.

The plant is undergoing major rehabilitation efforts to uprate the generating units to 46MVA.

Overall Technical Summary

Voltages Dual voltage rated secondary / high voltage winding – not autotransformer construction

Transformer is a GSU application with voltages and impedances studied through grid simulation to provide the best possible range of generator support to transmission operations. At the time of installation, the transformer will be installed in a 69 kV system.

In the future, the switchyard may be upgraded to 161 kV.

Multiple design solutions are possible, but the impedances and number of external bushings (only 3 high voltage leads brought out) may not be changed.

Impedance, high-low, at ONAN rated current, subject to IEEE tolerances:

(1) 69 kV: 7.5 (required impedance)

(2) 161 kV: minimum 7.5, maximum 12 (anywhere in this range)

High Voltage and High Voltage Neutral Section 48 19 23.04, paragraph 2.8.2 Resin-impregnated Synthetic (RIS) design

Low Voltage Bushings Section 48 19 23.04, paragraph 2.8.3 Porcelain or low-corona solid bulk Viton gaskets used for installation
