SUPER FLIGHT LINE ELECTRICAL DISTRIBUTION SYSTEM (SFLEDS)
 |
|
||||||||||||
| Overview: | The Super Flight Line Electrical
Distribution System (SFLEDS) reduces emissions created by diesel
engine-driven support equipment (SE) by replacing the existing
engine-driven power supplies with host facility power and redistributing
the conditioned power along the flight line. SFLEDS converts and
conditions 480V, 60 Hz, 3 phase host facility grid power to 120V, 60Hz,
single phase output for low voltage equipment and 115V, 400 Hz, 3 phase
for aircraft while still allowing outputs of 480V, 60 Hz, 3 phase for
heady duty equipment. Implementation of this system requires the
routing of 480V, 60 Hz power cable from the host facility grid to the
SFLEDS site. SFLEDS configuration includes frequency converters,
transformers, and electrical controls. | |||||||||||||||||||||
| Compliance Benefit: | If the SFLEDS is used in place of diesel
engine-driven SE the facility will decrease exhaust emissions. It
may also decrease the need for a facility to obtain an air permit under
40 CFR 70 and 71. In addition, less
hazardous materials are used on site (i.e., diesel) so the possibility
that the facility would meet any of the reporting thresholds for that
substance under SARA Title III (40 CFR 355, 370, and 372)
and Executive Order 13148 is decreased. The decrease in
the amount of oil stored on site may also drop the facility below threshold
amounts for the requirement to develop and implement a Spill, Prevention,
Control, and Countermeasure (SPCC) Plan under 40 CFR 112.
Note that additional electricity will be consumed with this technology and
that this is at odds with the energy conservation requirements of EO 13123.
The compliance benefits listed here are only meant to be used as general guidelines and are not meant to be strictly interpreted. Actual compliance benefits will vary depending on the factors involved, e.g., the amount of workload involved. | |||||||||||||||||||||

| Safety and Health: | Proper design, operation, and
maintenance of the equipment is required for its safe use. Trained personnel
must perform installation of electrical systems.
Consult your local industrial health specialist, and your local health and safety personnel prior to implementing this technology. | |||||||||||||||||||||

| Economic Analysis: | The following conservative 1997 estimates are based on the installation of a SFLEDS
prototype. Actual costs for SFLEDS operation may be lower and will
vary based on the equipment application.
