摘要
逆变电源的并联对于扩大系统供电容量、提高供电系统的可靠性等具有重要的意义。本文详细分析了逆变器并联的原理,提出了一种采用无主从式方法消除逆变器并联有功环流和采用CAN现场总线消除逆变器并联无功环流的数字均流方案,这种方案可以有效的减少并联系统中逆变器之间的相互影响,提高了并联系统的工作可靠性能。该方案在3kVA逆变器并联系统中得到了成功的运用。
The parallcl operation of inverters is very important to improve the capacity and reliability of the power system. This paper analyzed the principle of inverters＇ parallel operation, proposed a method through which we could solve circumfluence based on non-master-slave and digital current-sharing in the parallel operation of inverters. This method has been successfully,used in the 3kVA inverters＇ parallel operation system.
