Abstract
The design is for 10 KV regional electrical substation and part of the relay and design.
Electrical design are mainly based on raw data provided by the situation and taking into account the substation in the power system in which the position in which its geographical environment and its power transmission, through a technical and economic analysis and comparison, determine a reasonable Electric Wiring the main programme, select the appropriate electrical equipment.
Protection is part of the focus of this design. 10KV belong to the pressure distribution network, which extends to the electricity load centres or residential area, directly face the industrial and mining enterprises and residents and other users of electricity needs, to ensure that users connecting link between the preceding play the role of power supply, power distribution network by 10 KV The position is very important, the power distribution projects, can guarantee security, economic and reliable operation, the design quality is an important condition.
In addition, this design also has two plans, a power supply system maps, another for the protection and automatic device configuration map.
Key phrase: The main electrical wiring relay setting calculation automatic device
