“Masters of Space, Home of the 50th Space Wing!”

BACKGROUND:

The 50th Civil Engineer Squadron is seeking proposals to replace three mission essential systems in building 600, Central Utility Plant (CUP). (1) Replace the existing transformers, CT-1, CT-4, CT-7, CT-2, CT-5, & CT-8, common generator grounding resistor, interconnecting lines, and grounding system in the transformer yard. (2) Replace eight roof mounted exhaust fans connected to seven wall louvers controlled by thermostats located in the power generation system area. (3) Replace the existing obsolete models Woodward synchronizers, load controllers, custom PLC based generator controller, and the generator operator Human Machine Interface (HMI) computer and programming.

1.1. Transformer and Common Generator Grounding.

The six (6) transformers provide electrical power for mission critical HVAC equipment such as chillers, water pumps, boiler, and cooling towers in CUP. The common generator grounding resistor prevents damage to the generators by minimizing fault currents during electrical faults because the medium-voltage (MV) generators are not designed to withstand full fault current during an electrical fault. The existing transformers, common generator grounding resistor, interconnecting lines, circuit breakers, grounding system and other components are 20 to 30 years over their life expectancies and are in need of immediate lifecycle replacement. Symptoms of failing transformer and common generator grounding resistor have been noticed such as abnormally high temperatures due to defects on the forced cooling fans, and oil leaks in gaskets and valves. In addition, recent installation of Variable Frequency Drives (VFD) on the chillers creates harmonic currents in the power supplying system requiring K-factor transformers. K-factor transformers are designed to withstand the heating effects of harmonic currents created by loads like VFDs.

It is essential to replace the transformers and common grounding resistor to ensure uninterrupted reliable power to the mission critical HVAC equipment and to prevent failure of the power generating system.

Refer to the transformer drawings, for specific design and requirements.

1.2. Replacement of Roof Exhaust Fans and Wall Louvers.

` Schriever AFB has seven (7) generators in the CUP that provide backup power to the base. There are eight

(8) roof mounted exhaust fans connected to seven (7) wall louvers that turn on when generator room temperature reaches a certain level. In 2009, three (3) of the generators were replaced with new Caterpillar generators. During startup testing, a high bearing temperature alarm was activated. Initial observations from Wagner Power Systems showed improper and insufficient air flow. Initial calculations also show that the existing exhaust fans may be too small to provide adequate airflow. It is essential to replace roof-mounted exhaust fans, wall louvers, louver actuators, and thermostats to maintain cool temperatures in the power generation area.

Refer to the exhaust fans design analysis and drawings, for specific design and requirements.

1.3. Replace of Generator Synchronizers and Load Controllers.

Generator Synchronizers connect emergency power generators to the utility grid through the process of line-synchronization which amounts to generating voltages and phase that match the grid so that the machine can be electrically connected. Load Controllers provide load control across the base electrical system by operating intertie circuit breakers over an Ethernet communication network to control complex generator system.

The existing Generator Synchronizers and Load Controllers are over 20 years old Woodward Generator Synchronizers and Load Controllers which have not been produced by the manufacturer for seven (7) years.

Repair parts for the equipment are no longer available. Some of the current synchronizers have failed resulting in Schriever AFB not being able to synchronize the seven generators with utility power. It is vital to update the equipment to provide fail-safe emergency power to the base critical missions in the absence of utility power. Replacement of nine (9) Woodward synchronizers and four (4) load controllers with new modern models, programming synchronizers and load controllers, and interconnection wiring updates are required to complete this modernization and replacement work.
