AUTOMATED TEST FACILITY FOR GROUND-BASED EXPERIMENTAL TESTING OF SPACECRAFT POWER SUPPLY SYSTEMS Russian patent published in 2021 - IPC G01R31/00 

FIELD: aerospace technology.

SUBSTANCE: automated test complex for ground-based experimental testing of spacecraft power supply systems refers to conversion technology and can be used for ground-based testing of spacecraft power supply systems that receive electricity from solar battery simulators and battery simulators. The task is solved by the fact that in an automated test complex for ground-based experimental testing of spacecraft power supply systems, connected to the tested unit of the spacecraft’s energy-converting equipment (ECE) and containing simulators of solar and electric batteries, as well as simulators of spacecraft load devices, an automated control system (ACS) and a Server in which all units of the complex are integrated into a single Ethernet information network, each of the solar and electric battery simulators and the load simulator is connected to a corresponding separate uninterruptible power supply (UPS) unit, each of which is connected to an industrial three-phase network, while all these UPS are connected to each other in parallel, and their outputs are synchronized, while the automated control system and the Server are also connected to the autonomous three-phase AC network formed by them.

EFFECT: increase in the fault tolerance and reliability of the automated test complex during ground-based experimental testing of spacecraft power supply systems due to the formation of an autonomous three-phase AC network.
