Abstract

The invention discloses a common direct current bus type aircraft starting power generation system simulating method and device. The simulating device is used for simulating the starting and power generation processes of an aircraft starting and power generation system, and testing the aircraft starting and power generation system during research, development and testing phases. The simulating device comprises a direct current power supply, a starting generator control converter, a starting generator simulator, a circulating current suppression reactor, a starting generator simulator control system and a host computer. The invention further discloses the simulating method of the common direct current bus type aircraft starting power generation system simulating device. According to the invention, the simulating method and device simulate the starting and power generation processes of an aircraft; the parameters of the device can be flexibly modified; the power energy loss is small; a huge cooling device is omitted; and the lead time and the development cost are shortened.

Description

technical field [0001] The invention belongs to the field of aviation electrical systems, and more specifically relates to a method and device for simulating a common DC bus type aircraft starting and generating system. Background technique [0002] With the rapid development of the aviation industry, the aircraft is developing in the direction of multi-electricity and full-electricity, and the aircraft starter power generation system is one of the key equipment for multi-electricity and full-electricity. At this stage, the test of the aircraft starter generator system mainly uses the actual starter generator for testing. During the starting process, the mechanical load carried by the starter is usually a synchronous generator, and the load torque required by the starter is generated by controlling the output power of the synchronous generator. Such a test system has complex system, poor reliability, high hardware cost, The characteristics of low power utilization. In the ...
