1. General information on the project

Currently, the 330 kV Substation "Zhovtneva" there are two three-phase autotransform capacity of 200 MVA, 330/110/35 kV voltage transformer capacity and four 3x40 + 1h60 MVA 110/35/10 kV voltage.

330 kV air isolated switchgear operates on a "block line - two autotransformer" and has three connection:

- АТ1 – autotransformer – 200000/330;

- АТ2 – autotransformer – 200000/330;

- WL- 330 kV “Novokievskaya”

Existing equipment AIS-330 kV has fulfilled certain resource time, morally and physically obsolete and should be replaced. Panels of relay-boards and management of AIS 330 kV are in the income statement.

AIS - 110 kV operates on a "two working and bypass busbars" has 14 accessions:

- Т1 – transformer – 40000/110;

- Т2 – transformer – 40000/110;

- Т3 – transformer – 63000/110;

- Т4 – transformer – 40000/110;

- CWL-110 кВ «Politeknic – 1»;

- CWL-110 кВ «Politeknic – 2»;

- CWL-110 кВ «Motocikletnaya – 1»;

- CWL-110 кВ «Моtocikletnaya – 2»;

- WL-110 кВ «Severnaya – 1»;

- WL-110 кВ «Severnaya – 2»;

- CWL-110 кВ «Svitoshino – 1»;

- CWL-110 кВ «Svitoshino – 2»;

- АТ1 – аutotransformer – 200000/330;

- АТ2 – autotransformer – 200000/330;

In the future, the SS has no possibility to expand the territory under the exception, new accessions, which are planned to make the substation until 2020, in the above privacy joining AT-3, CL-330 kV "Zapadnaya - Zhovtneva" 110 kV

.

24. Natural and climatic conditions in the facility

Wind load in accordance with the DBN V.1.2-2: 2006 "Loads and effects" - 400 Pa;

Snow load - 1600 Pa;

The depth of soil freezing - 1,05 m;

Seismic activity - up to 6 points (according to DBN V.1.1-12: 2006).

25. Land improvement

For the purpose of improvement, the former AIS-330 kV, 110 kV arranged a protective coating of fractional crushed stone thickness of 0.15 m. On the territory of the construction and installation work is carried out landscaping by seeding grass and planting of shrubs.

26. Requirements for the electrical parameters of the network
