The Design Of 10KV Substation And Power Distribution
System
Abstract The substation is an importance part of the electric power system, it is consisted of
the electric appliances equipments and the Transmission and the Distribution. It obtains the
electric power from the electric power system, through its function of transformation and
assign, transport and safety. Then transport the power to every place with safe, dependable,
and economical. The region of factory effect many fields and should consider many
change to give or get an electric shock a mission for carrying and
customers carries etc. circumstance, make good use of customer data proceed then carry
calculation, ascertain the correct equipment of the customer. At the same time following the
choice of every kind of transformer, then make sure the line method of the transformer
substation, then calculate the short-circuit electric current, choosing to send together with the
electric wire method and the style of the wire, then proceeding the calculation of short-circuit
electric current. This first step of design included:(1) ascertain the total project (2) load
analysis(3) the calculation of the short-circuit electric current (4) the design of an electric
shock the system design to connect with system and the choice of line project (5) the choice
and the settle of the protective facility (6) the contents to defend the thunder and protection of
connect the earth.
