Why are some substations called simple stations?

Because the construction of a conventional substation of the same size, invested capital of about 5 million, covers an area of more than 2 acres, is more than 10 times the simple substation. The construction cycle usually takes 6 months (4 months for civil construction and 2 months for installation and commissioning. This does not include the preliminary feasibility study report, preliminary examination, approval, land acquisition and other related procedures for the time.

Standing outside the substation, for the advantages of simple substation:

One is the construction time is short, about 15 days can be put into operation. While the construction cycle of the conventional station usually takes half a year.

The second is simple procedures, do not need to go through a series of approval procedures.

Third is to save land, covers an area of only 120 square meters. While the conventional station occupies an area of 1,200 square meters.

Fourth, there is no need to acquire land, because the site area is small, occupying land generally provided by the local government. Now the land price is high, an acre of land also need hundreds of thousands of dollars.

Fifth, high efficiency. Simple substation is generally built in low-voltage areas, put into operation can significantly improve the voltage quality, but also greatly increase the power supply. At the same time, because there is no long-distance access lines, line loss is very low.
