Abstract

Substation is an important part of the power system, which directly affects the entire power system security and economic operation of power plants and the user is to contact the middle part, plays the role of transformation and distribution of electric energy£¬intends to build a 220 kv substation of a regional.

The design of the book introduces the regional 220kv electrical substation design a part of the content and design. The design of the contents of the electrical substation 220kv main regional cable choice, the main transformer, the transformer used in the choice of bus, circuit breakers and isolation switch option,the configuration of transformer,220kv,110kv,10kv line choice and short-circuit current calculations.The design of the main high pressure also had a choice of electrical equipment and computing, such as circuit breakers,isolating switches,voltage transformers,current transformers and so on.In addition,a lighting protection design and computing£¬general layout of electrical the choice of power distribution unit and the protection equipments and so on.,increased the safety of the entire substation.

Keywords:substation; main connection; transformer
