Research on an Unstable Fault Protection Circuit for Aero-AC Generator

Firstly, the factors of unstable fault of AC generator and the rule of unstable fault is analyzed. Then, combining the concept of stability and the factors affecting stability, a circuit is researched to protect the unstable fault of AC generator effectively. Finally, the core circuit pump circuit in the protection circuit is analyzed by theory and simulation, and the rationality of the unstable fault protection circuit is verified.
