摘要
直流短路电流计算方法是船用直流综合电力系统设计的重要组成部分,其设计影响着直流综合电力系统的保护设计方案和运行的安全可靠性。文章阐述了船用直流综合电力推进系统短路电流计算原理及计算方法,针对直流侧两极短路故障进行分析,充分考虑系统故障后的暂态和稳定过程,并给出相应的计算公式。结合实际算例,通过Matlab的Simulink平台仿真验证了计算方法的正确性。
DC short circuit current calculation method is an important part of marine DC integrated power system design. Its design influences the protection design scheme and system of the DC integrated power system to operate safely and reliably. The paper expounds the principle and calculation method of short circuit current for shipboard DC integrated power propulsion system. Aiming at the short circuit faults on the DC side and fully considering the transient and stabilization process after system faults, the corresponding calculation formula are given. Combining with the actual example, through Simulink platform of MATLAB, the correctness of the calculation method is verified.
