Abstract
The present disclosure relates to a protection system for synchronous generators or motors used in power converter arrangements, particularly in marine applications. The system provides enhanced fault isolation, redundancy, and operational safety for electrical propulsion and power generation systems. More specifically, the disclosure addresses the need for selective fault isolation in power converters, ensuring that failures do not lead to total system shutdown. The disclosure is also directed at a power system including a protection system.
Claims17
A protection system for a synchronous generator or motor in a power converter arrangement with a controller and at least two converters, comprising:
- a plurality of circuit disconnection devices each configured to interrupt the power supply to one converter,
- a fault detection device, such as a current sensor and/or or fuses for detecting faults of the converters,
- wherein the controller triggers a remote open signal to at least one of the circuit disconnection devices for interrupting the power supply to a converter upon detection of a fault condition, wherein each disconnection device operates independently to interrupt the power supply of a faulty converter, enabling continued operation of the remaining converters.
