At the present time electrical power system, electrical equipment and electrical systems are widely used on modern aircrafts of civil aviation, performing different functions. As a major part of aviation equipment, these systems have combined the sources of electrical energy, the electrical network of the distribution system and consumers of electricity. On modern aircraft the main sources of electric energy generators are of three-phase current voltage of 200/115 V, stable constant frequency of 400 Hz. From trouble-free operation of the system of electricity depends on the efficiency of all systems of the aircraft, powered by energy current and will eventually secure the essential task of flight for the carriage of passengers, cargo, etc. In the given work the analysis of the power system three-phase alternating current of an aircraft for example an aircraft Il-96. Basic four-channel system AC three phase 200/115 V, stabilized frequency of 400 H is considered. The composition and types of protection channels generate are presented. Strengths and weaknesses of the existing system of protection against short circuits in the generator or feeder, from the increase in voltage in any phase, from the deviation of frequency, from breakage of any phase, overload channel when current in any phase, and so on have been identified. Proposals for improving the existing protection of power supply system with a view to its further efficiency with high reliability and dependability have been developed and presented.
Keywords: reliability, safety, operability, reliability, electrical equipment, electrical systems.
