Research of DC Power System Stability Analysis and Validation for Geosynchronous Orbit Satellites

The stability of power system is one of the key elements of reliable on orbit flight of high orbit communications satellites. In particular, the stability and responsiveness of the buses are critical in the face of large dynamic loads as well as TDMA loads with frequency characteristics. First, the article analyzes the key elements that affect the stability of bus stability, and then proposes a comprehensive analysis method for satellite load characteristics. As the serious condition based on transient load, simulation analysis and experimental verification were carried out on the bus stability. The relevant analysis and verification cover the working mode of the power system in orbit. Besides, the stability design of the power system was further verified by analyzing the telemetry data from a satellite in orbit. The analysis and verification method provides important references for the stability design of the satellites power system.
