Abstract

The invention discloses a semi-physical simulation system of a satellite power supply. The system is characterized in that a solar simulator, a bus load, a storage simulator and the like are connected with a power supply control unit based on a way of combination of software and hardware. A main control computer carries out ground simulation of a satellite power supply system. An on-orbit working mode of a satellite power supply system is simulated and state switching of various on-orbit operation conditions is realized; setting of various power system parameters and operating state monitoring are completed and integration of storage battery charging and discharging management is realized; and the operation demonstration of the power supply system is realized and various teaching training modes are set, so that teaching and training work of various engineering professionals can be developed flexibly.

Description

technical field [0001] The invention relates to a satellite power supply system simulating a space on-orbit operation state in a ground environment, in particular to a semi-physical simulation system of a satellite power supply. Background technique [0002] As the core system for energy regulation of the whole star, the satellite power system provides continuous and stable energy for the whole star during the flight in orbit. Because satellites operate in space, many environmental conditions such as magnetic field, radiation, atomic oxygen, etc. cannot be completely simulated on the ground, especially the solar illumination angle, radiation loss factor, illumination and earth shadow time, etc., which are closely related to power supply design. It is difficult to simulate on-orbit working conditions 1:1 on the ground. Moreover, the traditional satellite power simulation test consumes a lot of manpower, material resources, and time. Various types of ground test equipment are...
