摘　　要：由于超导轴承的特殊运行机理,使得超导飞轮的动态运行特性与机械飞轮存在较大差异,并会对其充放电性能造成影响。从超导飞轮和机械飞轮的共振特性和转速特性角度,对电力电子系统及母线电压的影响进行分析。在Matlab/Simulink软件中进行超导飞轮充电系统的搭建和验证,分析得出,超导飞轮相对机械飞轮来说,对转速的波动抑制能力较差。但是由于前端稳压电路的存在,转速波动对母线电压影响不大。相关研究及结论对于超导飞轮工程应用中,充电系统及电压稳定系统设计与优化具有一定参考价值。Because of the special operation mechanism of superconducting bearing, the dynamic operation characteristics of superconducting flywheel are quite different from those of mechanical flywheel, and the charging and discharging performance of superconducting flywheel will be affected. In this paper, the influences of resonance and rotational speed characteristics of super conducting flywheel and mechanical flywheel on power electronic system and bus voltage were analyzed. The superconducting fly wheel charging system was built and verified in Matlab/Simulink. Tthe analysis shows that the superconducting flywheel has a poor ability to inhibit the fluctuation of rotation speed compared with the mechanical flywheel. However, due to the presence of front - end voltage stabilizing circuit, the speed fluctuation has little influence on bus voltage. Relevant research and conclusion could have certain reference value for the design and optimization of charging system and voltage stability system in superconducting fly wheel engineering application.
