Generator System Design for a Li-Ion Battery and Micro Turbine-Generation Based High Power Density Series Hybrid Power System

摘要

This paper focuses on the generator system design of the hybrid power systems based on Li-ion battery and micro turbine generator. To improve not only the dynamic performance but also the safety and reliability of system, two electrical architectures are proposed based on the analysis of the system demand and the characteristics of power supplies. The dynamic process of rectifier protection is analyzed. A permanent magnet synchronous generator's parameters design method is developed considering the load rej ection self-adaptive constraint of MTG, unity-power factor operation and other design constraints of PMSG. Simulation studies are presented to illustrate the feasibility of the proposed method.
