摘要
该文所研究的是磁浮列车非接触紧急供电系统的工程化设计实现。文中首先介绍了非接触紧急供电的原理,然后通过建立在磁浮列车中的非接触紧急供电系统的模型,得到工程化的设计方法。针对磁浮列车中非接触紧急供电系统功率传输能力较差的问题,引入串联补偿的方法提高整个非接触紧急供电系统的功率传输能力。分析了串联补偿方法的原理,并推导磁浮列车附加发电线圈匝数的设计公式。最后通过在一台比例1:4实验电路上的实验结果验证了前面的分析。实验结果表明文中所述的设计方案可以明显改善磁浮列车紧急供电系统传输能力,并且可以大大减小充足供电时所需要的辅助供电逆变器容量。
The engineering design of contactless emergency power supply is presented in the maglev. The theory of contactless emergency power supply is introduced first, and then the model of contactless power supply system used in the maglev is obtained. From the model, the parameters design of the system can be achieved. To improve the power transmitting capacity of the proposed system, series capacitor compensation is introduced into the proposed system~ The principle of the capacitor compensation is analyzed, and then the design of auxiliary linear generator windings is given. Finally the experiment results on the 1：4 prototype are given to verify the analysis before. The experiment results show that the design can effectively improve the performance of the contactless emergency power supply system in the maglev. Then the power rating required of the auxiliary inverter can be reduced obviously.
