| Abstract: | DC short-circuit current calculation method is an important part of marine DC integrated power system design. Whether its design is correct or not depends on the protection design scheme and system of the DC integrated power system to operate safely and reliably. This paper expounds the principle and calculation method of short-circuit current for shipboard DC integrated power propulsion system. It mainly analyzes the short-circuit faults on the DC side and fully considers the transient and stabilization process after system faults. And give the corresponding calculation formula, combine the actual example, through simulink platform simulation of MATLAB to verify the correctness of the calculation method. |
