Electrical Load Management System Aircraft

Aircraft performance is directly connected with the reliability of electrical systems and subsystems.

Electrical load management system aircraft.

Generally aircraft electrical systems utilize both ac and dc power. The existing mv 22 block c aircraft electrical power system has been selected as the configuration baseline for this effort. 4 utilize smart load shedding to optimize aircraft. The system is comprised of 4 generators 3 converters a main battery 6 main ac buses 4 main dc buses 5 circuit breaker panels 173 dc loads 21 single phase ac loads and 50 three phase ac loads.

Using micro computer technology instead of manual operation for automatic control and management of the load has improved the existing method of distribution and load management which has enhanced performance of aircraft and its maintenance of power system. An electrical load management based on fixed priorities of the loads is considered a conventional implementation as applied in today s aircraft systems. The main function of an electrical system is to generate regulate and distribute power throughout the airplane. The electrical power network on this aircraft figure 1 consists of two 115 200 volt three phase 400hz generating and distributing systems.

1 monitor bus power quality and excess power source capacity. 2 monitor status of solid state power controllers smart relays and other circuit protective devices. 3 maintain data bus communications within the electrical load management system and with other aircraft systems. Aircraft electrical load management center an important part of the aircraft power supply system solves the automatic management of aircraft load via a multi channel transmission bus and a solid state power controller.

The advantages and disadvan tages of such a system are presented. The new technology should provide improvements to power distribution load control fault recognition isolation and protection and automation with features to. Slated to begin testing in 2016 the power generation system will generate twice the power generation of the current 777 system while the elms will control 30 more power in the same size envelope. We re proud to provide the electrical load management system elms backup generator and backup converter for the boeing 777x.
