2. Monitoring subsystem gis 330/110

   1. Purpose and functions

The monitoring subsystem is designed for continuous measurement, recording and display of technical condition and the basic parameters of the switchgear in normal, pre-emergency and emergency modes, including:

- monitoring density sulfur hexafluoride gas-insulated compartments in cells;

- monitoring of partial discharge in GIS;

- accounting circuit switching resources;

- resource accounting mechanical switches;

- collection, display and archiving of monitored parameters;

- selfdiagnostic system;

- collection, storage and archiving of monitored parameters.

- transmission of information in the process control system;

The system should be continuous monitoring of the partial time-series in the GIS by UHF.

To do this in the compartments of cells switchgear manufacturer shall establish primary-WIDE microwave sensors.

The signals from these sensors must come through the blocks of the primary signal conversion and intermediate routers cabinets in price-tral server data processing system, which must be carried out analysis of the FA, display and archiving, as well as the issuance of warn-tive or alarm in the event of the intensity of the FA specified by the manufacturer switchgear installations.

The system should carry out the type of the detected signal interpretation of the FA in real time (at least 5 types of defects) through the built-fuzzy logic algorithms, etc..

GIS system should fix the mechanical wear of the resource (number of starts) drive circuit. The number of starts of the drive mechanism must be fixed, but in a special programmable counter. Forming a team to increase the counter should be on the block contact with the water.

3. Auxiliaries substation

   1. Shields own needs

Two-piece board of own needs (auxiliaries) AC 0.4 kV is powered by two auxiliary transformers.

The shield of alternating current switchgear installed in a building 330, 110 kV and comprises:

• Input Panel - 2 things;

• panel sectional connection - 1 things;

• panel feeders – 2 things.

Number of outgoing lines specified project.

Redundant power supply is performed on the side of 0.4 kV auxiliaries. From SON 0.4 kV consumers eat 330 kV gas-insulated switchgear, the switchgear 110 kV substation control. Power drive circuit 330 kV, 110 kV AC accepted.

The configuration of alternating current of 0.4 kV is finally determined in the design process.

Operational current on SS- DC 220.

In accordance with the "Norms of technological design SS AC higher voltage 6-750 kV" for the supply of primary and backup protections RU-330 kV, 110 kV, autotransformers provides installation in the substation control building in separate rooms of two sealed batteries 220, each of which is attached to his shield DC. to recharge aggregates. The type and capacity of the batteries should be specified at the design stage.

Shield the DC (direct-current board) 220 is installed in the building of the switchgear 330, 110 kV. The composition of the current board includes chargers. From the current board feed consumers switchgear 330 kV, 110 kV gas-insulated switchgear. Number of outgoing lines specified project.

The final configuration of their own needs DC 220 is determined in the design process.
