An airplane power source system control and protection experiment device is characterized by comprising a frequency converter, a motor, an alternating current synchronous power generator, a power generator control unit, an alternating current power distributing center, an alternating current load for an analog airplane, a rectifier, a direct current power distributing center, a direct current load for the analog airplane, a central controller and the like. The airplane power source system control and protection experiment device solves the problem that an experiment platform of a traditional airplane power source system is complex in structure, high in price, poor in safety and the like, can simulate moving performance of the airplane power source system under different conditions and can measure data of voltage, current, frequency, power, power factors and the like. The airplane power source system control and protection experiment device can provide a basis for airplane power source system optimization control, protection and reliability analyzing and research by simulating different flying states of the airplane power source system in different flying states and possible influence on operation performance of the airplane power source system caused by built-in load changing. Investment of the airplane power source control and protection experiment device mostly occupies about one tenth of that of a traditional airplane power source system experiment teaching device, and the airplane power source system control and protection experiment device is low in operation cost and safe and reliable.
Description
technical field [0001] The invention relates to an aircraft power supply testing experimental device. Background technique [0002] The aircraft power system is composed of a power supply system and a power distribution system. Its function is to provide electrical energy to all electrical equipment on the aircraft (such as flight control system, avionics system, fire control system, etc.) to ensure the safe flight of the aircraft and complete transportation. and combat missions. With the rapid development of large aircraft in the direction of multi-electricity and all-electricity, the system structure and control of modern aircraft power systems are becoming more and more complicated. It is becoming more and more complicated. In addition to conventional linear loads, there are also a large number of non-linear loads such as constant power loads and regenerative loads. This puts forward urgent requirements for the stability, reliability and power quality of traditional airc...
