The invention relates to a method and a system for emergency operation of a modular multilevel converter. The modular multilevel converter includes a central controller and a plurality of battery modules. A respective switching state is given by the central controller to a respective battery module during each switching stroke, by means of which a respective energy accumulator is connected to a respective energy accumulator of a respective adjacent battery module. And the corresponding fault energy accumulator is reported to the central controller through module monitoring. For a respective battery module having a faulty energy store, a bypass switching state (210, 220) is determined at each further switching path. If a threshold defined by a specified number of faulty accumulators permissible by operation of the modular multilevel converter is exceeded, an emergency operation is caused, comprising at least the steps of: changing the operating state from the "operating mode" to the "maintenance mode"; displaying the change to a "service mode" in an operator display; the further operating time is limited until the service begins.

    本发明涉及用于模块化多电平转换器的紧急操作的方法和系统,该模块化多电平转换器包括中央控制器和多个电池模块。相应电池模块在每个切换行程由该中央控制器给予相应切换状态,相应蓄能器通过该切换状态连接到相应的相邻电池模块的相应蓄能器。通过模块监测向该中央控制器报告相应的故障蓄能器。对于具有故障蓄能器的相应电池模块,在每个另外的切换行程确定旁路切换状态(210,220)。如果超过由模块化多电平转换器的操作可容许的故障蓄能器的指定数目所限定的阈值,则导致紧急操作,该紧急操作至少包括以下步骤:操作状态从“操作模式”改变为“维修模式”;在操作者显示器中显示改变为“维修模式”;限制进一步操作时间直到维修开始。
