Electrical Load Management System Aircraft

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. 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 normal in flight power sources for the electrical power system are two oil spray cooled brushless 90kva integrated drive generators idg.

4 utilize smart load shedding to optimize aircraft. The advantages and disadvan tages of such a system are presented. Generally aircraft electrical systems utilize both ac and dc power. 3 maintain data bus communications within the electrical load management system and with other aircraft systems.

2 monitor status of solid state power controllers smart relays and other circuit protective devices. It can cut and reconnect loads depending on their importance. We re proud to provide the electrical load management system elms backup generator and backup converter for the boeing 777x. 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.

1 monitor bus power quality and excess power source capacity. The new technology should provide improvements to power distribution load control fault recognition isolation and protection and automation with features to. The main function of an electrical system is to generate regulate and distribute power throughout the airplane. An electrical load analysis ela is a check of the aircraft electrical system to ensure that the aircraft electrical system has the capacity to handle normal and emergency situations.

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. An electrical load management based on ﬁxed priorities of the loads is considered a conventional implementation as applied in today s aircraft systems. The electrical power network on this aircraft figure 1 consists of two 115 200 volt three phase 400hz generating and distributing systems. Aircraft performance is directly connected with the reliability of electrical systems and subsystems.
