Comprehensive test method of small satellite power subsystem

Abstract

The invention discloses a comprehensive test method of a small satellite power subsystem. In the method, a solar cell array is replaced by a solar matrix simulator; a ground wired test and control platform of a satellite comprehensive test system is used to transmit wired instructions and collect important parameters; and ground test and control equipment, a remote measurement and control front end and a test computer are used to transmit remote control instructions and collect remote test data. After the satellite is electrified, the on operation time, off operation time and remote control command transmission time of the solar matrix simulator are reasonably controlled, the working state of a power subsystem is set, various parameters and states are monitored and interpreted, and thus, various test items are accomplished. In addition, a method of injecting normal or fault data blocks and program blocks is adopted to test the up injection function, reliability and fault tolerance are tested. The method has high test coverage, clear and definite flow, simple and reliable operation and convenient construction.

Description

technical field [0001] The invention relates to a comprehensive test method for a fully-adjustable bus small satellite power supply subsystem which adopts a distinction between a charging array and a power supply array. Background technique [0002] It is generally believed that satellites with a mass of 500-1000Kg are small satellites. As the power generation device of the small satellite, the power subsystem is the energy source of the entire satellite. It is mainly composed of a power controller, a battery pack, and a solar array. The power controller is used to centrally realize the control functions of the satellite power subsystem, including bus voltage Regulation, solar cell array output power split control, battery charge and discharge control, and interface with other subsystems. The performance and functional characteristics of the power subsystem directly affect the working status and lifetime of other systems. [0003] Satellite comprehensive test means that af...
