==METHOD AND SYSTEM FOR EMERGENCY OPERATION FOR A MODULAR MULTILEVEL CONVERTER - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240055978 titled 'METHOD AND SYSTEM FOR EMERGENCY OPERATION FOR A MODULAR MULTILEVEL CONVERTER

==Simplified Explanation==

The abstract describes a method and system for emergency operation of a modular multilevel converter with a central controller and multiple battery modules. The central controller assigns a switching state to each battery module at every switching stroke, connecting the energy accumulators of adjacent modules. Faulty energy accumulators are identified through module monitoring and reported to the central controller. If the number of faulty accumulators exceeds a threshold, emergency operation is triggered, switching to a repair mode and restricting further operation until repair.

* Central controller assigns switching states to battery modules
* Energy accumulators connected between adjacent modules
* Faulty accumulators reported to central controller
* Emergency operation triggered if threshold of faulty accumulators exceeded
* Switch to repair mode and restrict further operation until repair

### Potential Applications
- Power grid systems
- Renewable energy systems
- Electric vehicle charging stations

### Problems Solved
- Efficient management of battery modules in a modular multilevel converter
- Quick identification and handling of faulty energy accumulators
- Preventing system failure due to multiple faulty components

### Benefits
- Enhanced system reliability
- Minimized downtime for repairs
- Improved overall performance and longevity of the converter system


==Original Abstract Submitted==

method and system for emergency operation for a modular multilevel converter including a central controller and a plurality of battery modules. the respective battery module is given a respective switching state by the central controller at each switching stroke, through which a respective energy accumulator is connected to a respective energy accumulator of a respectively adjacent battery module. through a module monitoring, a respectively faulty energy accumulator is reported to the central controller. for the respective battery module with a faulty energy accumulator, a bypass switching state is determined at each further switching stroke. if a threshold value defined by a specified number of faulty energy accumulators tolerable for an operation of the modular multilevel converter is exceeded, an emergency operation is caused, which includes an operating state change from “operation mode” to a “repair mode”; display of the same; and restriction of a further operating time until repair.
