摘要： A method of converting a direct voltage generated by a decentralized power supply system into three-phase alternating voltage by means of a plurality of single-phase inverters (WR1-WR3), said alternating voltage being provided for supplying an electric mains, is intended to avoid inadmissible load unbalances using single-phase inverters. This is achieved in that, upon failure of one inverter (WR1-WR3), an asymmetrical power supply distribution is reduced by limiting the output of the other inverters. The method makes it possible to simplify three-phase voltage monitoring.
摘要翻译：一种通过多个单相逆变器（WR 1 -WR 3）将由分散电源系统产生的直流电压转换为三相交流电压的方法，所述交流电压被提供用于供电，旨在避免使用单相逆变器的不允许的负载不平衡。这是通过一个逆变器（WR 1 -WR 3）的故障而实现的，通过限制其他逆变器的输出来减小非对称的电源分配。该方法可以简化三相电压监测。
