ABSTRACT The main switchboard is a very useful and important part in the normal operation of modern ship, which is directly related to whether the ship can be safe, reliable and stable operation。 At the same time , it is also a measure of the level of ship manufacturing, at present, The technical level of ship main switchboard is relatively low and it’s development has a long way to go。

In this paper, the Yangtze River monitoring ship's main switchboard design as an example, from its shape, main function, principle and so on。, to complete the  main switchboard electrical design, The main contents of this paper include the following points:

(1)。The electrical design of the main switchboard, the main switchboard for screen design, the main include: synchronous screen, generator screen, the combination of the start

screen and load screen。 Details of the design of the specific principles、function and Design

reasons。

(2)。The simple principle and function of the management of ship  automatic power station complete the generator and car and splitting、heavy inquiries and other functions。

(3)。The calculation method of short circuit current in electric power system is introduced, including the calculation of short circuit current of AC power system and the calculation of short circuit current of DC power system。 Characteristics of short-circuit current calculation and calculation method of power factor。 Finally, the calculation procedure of short circuit current is introduced by an example。

Through this design, preliminary master the working principle of  ship  main switchboard each  screen  circuit 、 control principle  and function of ship  automatic   power

station, correlation method of short circuit current calculation。 To lay the foundation for future work in related fields。

Keywords: Ship Electrical Power System、Ship Main Switchboard、Generator、 Short-circuit current
