The Research And Realization For Ship Electric System Aided Design

The auxiliary design of ship electric power system is by applying the computer software,Comprehensive analysis the field of regularity and drawbacks part in electrical design.,To realize the purpose of assistant the design.The study area of this thesis is the generalized power system,which includes the lighting system and power system.During the traditional design work,this part design work contains vairous repetition work and complex statistical work,lead to a long design time.And according to different experience of designers,The quality of the designed drawings is uneven.This thesis detailed analysis the electrical system design principle and detailed design process,by Visual studio softward and C#program to study the use of AutoCAD secondary development,design a Marine electric power auxiliary system module,to assist in the design of the power system and the diagram.This thesis.main work is as follows:Simplify the drawing work of lighting system diagram and layout drawing.For lighting design,Establish a light Component library.through VS,set up a operation interface window.realize light component selection and arrangement work.Also can realize grouping and classification according component cable mark,and draw the system dwg automatic;Simplify the statistics list.After lighting layout or system diagram have been done,according to the type of components,statistical the quantity for layout or system drawing;Design the selection module of power cable sectional area.Module give Comprehensive consideration,contains different environment,different number of conductor and the bundled factors,input current or power etc.all can give recommended cable sectional area automatically;Design the Voltage drop calculation module.Module interface considered all effects of voltage drop.including electrical system,cross-sectional area,cable length,etc.,can automatically calculate the cable's voltage drop;Design Statistical module of distribution box load.Through picking up the power text in AutoCAD,the statistic list is shown in window,also can export the table data;Design the standard drawing frame insert function.Contains A1-A4 commonly used drawing frame.This thesis combine the principle of ship's electric power design and computer aided,design the electrical system design module.In the actual process of drawing design,the application is very convenient,and can greatly reduce the design time,improve the accuracy of the design.Module application,easy to be used in any computer,do not need to install additional software support.At the same time,the module design method is general,easy for modification and complement the module in later practical use.Also provide a thought for electrical computer aided design.
