Abstract:
   This paper deals mainly with the packets Electrical Electrical Control System Design based on the principles and methods and the conclusions of design options. This paper comprises three chapters, the first two chapters are mainly including hardware design and selection; Chapter III procedure forthe design.            
   Some of the main elements of hardware including : electrical diagram, the various components of the selection.
 Some of the main el ements of the software include : flowchart, PLC procedures.
The design drawings were completed DFYGRE sites using AutoCAD drawings mapping software.
The Office of the packages designed for Electrical Control for graduation design, the aim of which is to design practice, and by using their knowledge, linking theory with reality, tempering an independent analysis of the construction and electrical design solution to the problem, for the future work of laying a solid foundation.
