16、increasingly, the construction of electrical network is acting more and more important role with development. Electrical network takes a role of the bridge of producing -electrical energy enterprises and users,
17、 it is well known that electrical network is unsaid for the stability and reliability of power supply. The design of power system acts as important one aspect in the construction of electrical network, witch m
18、ust give a extra attention. This paper concisely have introduced method and the process of the distribution net design of high voltage. It should be according to the related information of user loads, each distribution s
19、tation site and the condition of power supply of existed power plants., making corresponding power balance ,and then determine every distribution transformer capacity and number. According existed some knowledge
20、and experience, imagine two kinds choosed scheme, compare through technical economy from some following aspects,require best design: 1 , select wire according to economic section, according to machinery strength
21、, corona, the current-carrying capacity etc. ,checking the wire model .2,Various choose schemes must be carried out calculationfor normal and fault condition by manual power flow calculation .Calculation result
22、are normal and fault voltage wastage conditions, remarking various wiring schemes. 3 .From loss , line investment, the electrical energy of various scheme lines, distribution system annual operation cost t as well as in
23、vestment of electrical place, carrying out economic comparison and synthesize. Finally,deside the bests scheme, that is choosed scheme.Draw system winding diagram in the design.Keywords: grid design;wire section choice ;
