Above, the 125vdc battery bank and Charger, provides power to the 120vac UPS inverter in the picture below and the 480 distribution panel to the left. The UPS powers the Control Room and HMI’s and other 120vac systems in an emergency condition.

The 24vdc NiCd battery bank and charger sits directly across from the 125vdc batteries. The 24vdc battery bank supplies control power to the controls.

On the left of the picture above, is the main 480vac accessory breaker. This beaker taps off 480 power from line side of the 480vac Viking Power output buss. This power is fed to the motor control center, and the large 480vac distribution breaker panel to the right.

Between the two, is the 120vac distribution breaker panel. Beyond the 480vac breaker panel and below the UPS system are two 120vac transformers for site power. One transformer feeds the control room and the other feeds the rest of the site. The distribution breaker boxes were built with a considerable amount of spares for additional equipment connections around the site that could be added if desired.

This is a picture of the motor control center. The motor control center has motor starters for the lube oil coolers fan motors (8) and spare buckets and starters for the additional fuel forwarding pumps or other auxiliaries that might be required at the final destination.

The MCC power cabling will route the field through the 480vdc power cable tray carrying the generator output leads.

The transformer protection panel above was constructed to provide protection for the two transformers that may be required to step up the 480vac site output voltage to match the line needs of the destination site. Two Pride Multi-Function Transformer Electronic Relays are provided for each transformer. Transformers are not provided with the Viking Power Project site.

The generators are also protected with the dual Pride Multi-Function Generator Protection Electronic Relays as seen in this picture.

The generator monitoring panel is also equipped with a digital readout of the generator operating parameters. A generator breaker open/close switch and generator lockout relay are also located on this panel.

The generator breaker shown above, is a 2000 amp breaker.

There is an individual synchronizing breaker for each unit. The synchronizing controls are contained in the control room. Unit #1 and #2 share one synchronizing panel, and unit #3 and #4 also share a synchronizing panel. The wall of the container to the right of the breaker will be cut to allow access to make connection of the switchgear buss to the line or step up transformers as required for the destination site.

In addition to the generator monitoring, the upper panel also contains the PT’s and the generator exciter shown in this picture. This is the original Basler voltage regulator for the generator. Digital potentiometers have been incorporated to interface with the new TurboNet Dash 1 controls to raise and lower the voltage.

All of the electrical components are new or used and reconditioned.
