Theoretical analysis and numerical calculation for stability of synchronous generator-rectification system

The operational stability of synchronous generator rectification system is studied: all variables of the system and their correlations are analyzed in detailed under mini disturbances, and the linear differential equation about the DC side average current is derived. The stability criterion of the rectification system is conducted and reasonably explained. All parameters that have influences on system´s stability are calculated and analyzed, and their ranges for a stable rectification system are given. Finally, the paper explains why and how the parameters affect system´s stability. The operational stability of synchronous generator- rectification system is completely and correctly recognized.
