摘要
随着船舶自动化水平的提高,船舶电网容量急剧增加,网络结构趋于复杂。早期的船舶短路电流计算标准国标(GB3321-82)和国军标(GJB173-86)主要局限于简单的馈线式网络结构,且由于忽略内容较多已经很难满足需要。本文根据发电机和电动机的基本理论建立较为精确的电源模型,并结合转移阻抗法计算任意船舶网络结构的短路电流。通过Simulink仿真验证该了该方法的正确性和有效性。
With the development of automation level the ship power capacity increases dramatically, and the network structure also tends to be more complex. The early short circuit current calculation standards such as GB （GB3321-82） and the National Military Standard （GJB173-86） are mainly used for the simple feeder network structure, and don ＂t meet the needs of complex power network. By establishing a more precise power model according to the basic theory of generators and motors, and combining with the transfer impedance method, this paper proposes a method to calculate short-circuit current of any network structure. The simulation results of the Simulink verify the correctness and validity of the method.
