Deployable Power Generation and Distribution System (DPGDS)

The Deployable Power Generation Distribution System (DPGDS) will replace the current Prime Power system in the field.

A new set of air transportable Bare Base electric power generation and distribution equipment is required to improve capability and reduce deployment requirements for existing and future US Air Force Harvest Eagle and Harvest Falcon Bare Base kits and US Army Prime Power units. A program has been instituted that will provide a systematic approach to optimizing the most cost-effective solution to the user requirements as identified in the Joint Operational Requirements Document (ORD). A high degree of interchange has occurred between the Government and the commercial world to reduce programmatic, cost and technological risk. The program is currently in Pre-Production phase.

The purchase of commercially available equipment to the maximum extent possible has been pursued through a competitive Firm Fixed Price (FFP) contract awarded 18 March 1998. The award, based on best value, was made to Radian, Inc, a single prime contractor with total system responsibility. Major subcontractors include Caterpillar, Inc. (CAT) for manufacture of generator sets; Alban Engine Power Systems (AEPS), a CAT dealership, for fabrication and assembly of the Prime Power Unit (PPU); Republic Electric & Development Company (REDCO), for digital control systems and switchgear; Tampa Armature Works (TAW) for secondary distribution equipment; and Applied Research Associates (ARA) for development of multimedia training programs. During the 10 month Phase I, Radian will demonstrate their equipment and participate in government conducted requirements verification testing designed to ensure threshold requirements are met by the proposed system and equipment. Upon successful completion of Phase I, Radian will conduct characterization testing and prepare for support of Qualification Operational Test and Evaluation (QOT&E). AFOTEC will perform QOT&E on the system. The Program Office, Air Logistics Center (ALC) and Users will evaluate commercial manuals and drawings to ensure completeness. Production for DPGDS systems, individual equipment, multimedia training, on-line technical help, training, QOT&E technical help, and contractor support will be available under CLIN options. Logistics support will be handled by Sacramento, Warner Robins Air Logistics Centers and Civil Engineering Maintenance and Instrumentation Repair (CEMIRT). A provisioning conference will be held to determine usage rates, spares and composition of support kits.

The Prime Power Unit (PPU) contains two Caterpillar 460kW generator sets with an integrated primary power distribution center, capable of delivering 920kW, 4160 V, 50/60 Hz, total power. Low load operations down to 200kW are possible without damage to the unit. Control of the unit is accomplished through on-board control panels (typical for single unit operation) or via a personal computer (PC) (typical for multi-unit operation). Up to four PPUs can be controlled from a single PC and the PC can be located up to 1500 feet from the units. The PPU incorporates an integrated enclosure/frame with access panels that contribute to the total structural integrity of the unit. The side access panels can be removed for quick removal and replacement of an entire genset using a forklift.

Each PPU contains two Caterpillar 3456 engines, two Caterpillar SR4B generators, two heat rejection radiators, an integrated Primary Distribution Center, a fuel tank, a transformer, and an integrated battery charging power supply with four 24 V batteries. There are two configurations of the PPU, differing only in the undercarriage area. The MEP PU 810 A is configured for low speed maneuverability only and can be transported aboard a C-130 aircraft. The MEP PU 810 B is configured with a "fifth wheel" and is DOT certified for highway travel, but cannot be transported aboard the C-130 aircraft.
