摘　　要：分析了辅助逆变器的中压供电模式、并联供电模式及各自的技术特点,重点介绍了分散并联和集中并联2种并联供电方式的原理、并联过程及故障检测方法。综合来看,并联供电控制难度大些,而生产和维护难度则大大降低。Medium voltage power supply mode, paralled operation power supply mode and their technical characteristics of auxiliary inverter were analyzed, focusing on the operation principle, parallel operation process and fault detection of concentrated and decentralized parallel operation power supply modes. On the whole, the control difficulty of parallel operation power supply is increased, but the operation and maintenance difficulty is reduced greatly.
