为研究便捷高效的船舶交流电力系统短路电流计算方法,从整体上把握短路电流的变化规律,建立船用发电机、电动机的数学模型,开发出VB、Excel、MATLAB三种软件联合编程方法,利用实船参数对船舶交流电力系统的短路电流进行研究分析,获得短路电流数据及图像.研究表明,该方法在获得精确计算数据的同时,可以生成"短路电流-时间"曲线,直观反映了短路电流随时间的变化规律.

To study a convenient and efficient calculation method of short-circuit current of marine AC power system,while grasping the change rule of shortcircuit current,the paper established the mathematical models of marine generators and marine motors,and developed the combined programming for VB,Excel and MATLAB.The parameters of the real ship were used to research the short-circuit current,and the data and images of short-circuit current were obtained.The accurate calculation data was derived,while the curve of short-circuit current-time was generated by using the proposed method,which intuitively reflect the change rule of short-circuit current with the time.
