Development of digital model and analyzation system for typical faults of low voltage DC system

The digital model for the typical faults of low voltage DC system is analyzed, and the analyzation system is developed to offline calculate and pre-analyses whether the fault results in mis-action of the low voltage DC system. Firstly, the digital model for typical faults of low voltage DC is analyzed based on the analytical method, and the mis-action power for typical faults is found. Secondly, the software for verification of the above analysis is developed, and typical cases are used to further verify the correctness and effectiveness of the developed software. In the tested case, the developed software can flexibly pre-analyses the mis-action of low voltage DC system for the targeted typical faults.
