Design of Dynamic Parameter Testing System for Satellite Power

When the satellite changes its working state, its power output will produce instantaneous jump. Accurate measurement of dynamic parameters of satellite power is the basis to ensure the normal operation of other modules. Aiming at the shortcomings of low automation level, low precision, poor data recording and analysis ability in dynamic parameter testing of satellite power system, a dynamic parameter testing system with high accuracy and automation level is designed, which integrates data acquisition, analysis and calculation, display and storage functions. Solar cell simulator and electronic load are used to simulate the output of solar panels and the power consumption change of loads when satellites are in orbit. With high-speed acquisition card, dynamic characteristic measurement unit is developed. Satellite power system and dynamic parameter measurement system are established and carried out. The test results show the reliability of the system.
