      1. Data exchange with other levels of control hierarchy

Transmission of operative-dispatcher’s data using IEC 60870-5-101 (104) should be provided for:

  • Dispatching control center of BEN

  • Dispatching control center of Regional ES

  • Dispatching control center of NPC “Ukrenergo ".

For provision of access to operative-dispatcher’s and process data of subscribers of upper level of control hierarchy, SHS means of ACS TP shall be equipped with corresponding soft- and hardware interfaces.

Information exchange should be ensured by redundant channels (provided by the Employer) with the supplied software redundancy switching equipment and gateway software redundancy scheme “hot-standby” or “parallel” operation locks.

The profiles of protocols shall be specified when the ACS TP is designed.

Software interfaces shall provide access to real-time data using measurements and status of key diagram, equipment, engineering communications, outer environment and so on.

Authorized and protected access (read-only) shall be provided to the following types of information stored in the ACS TP:

  • Historic archives of operating-process data, electric energy metering, event logs, measurement logs, results of processes recording and so on.

  • ACS TP configuration and state of software and technical components data.

  • Operative, process and technical regulatory documentation.

It is preferable that access to the data above is performed using standard SQL-inquiries to historic and informational data base of the ACS TP and secure communication links with the servers of the system.

    1. System-wide functions

  • Organization of intra-system and inter-system communication facilities, data processing and transmission to adjacent and higher levels.

  • Testing and self-diagnostics of software, hardware and channel (network) portions of SHS components.

  • Synchronization of SHS components and ACS TP-integrated independent digital systems using universal time system signal.

  • Diagnostic data archiving and storage in specified formats and in specified time intervals

  • Protection against unauthorized access, information security and separation of access right (level) to the system and functions, including control functions.

  • Documentation, sending of reports and protocols to print-out in specified form, maintenance of operating data base, daily record and operating log.

  1. Description of the Automation Object

The installation:

GIS-330 kV, “Breaker-and-a-half Scheme»:

- АТ-1, АТ-2

- АТ-1,АТ-2

- 1 WL

Total – 2 fields (one incomplete), 3 connections (5 switch modules). To provide the ability to connect to the ACS TP SS 1 backup field for 3 switches (AT-3 + 1 CL 330 kV, perspective).

GIS-110 kV, the scheme “Two working busbars, sectioned by switches, with two busbar couplers, without transfer busbar»:

- АТ-1, АТ-2

- 4OHL + 2CL + 2OHL/CL

- Т1, Т2,Т3,Т4

- 2SS, 2BC.

Total – 14 connections (18 switch modules).

To provide the ability to connect to the ACS TP of substation 5 connections (AT-3 + 4 CL 110kV, perspective).

  • AIS – 35 kV, the scheme “Two working busbars with busbar coupler, without transfer busbar”, including:

- 14 high-voltage circuit-breakers

- 1 BC (Busbar coupler)

- 2 feeders (VT-35-I b.; VT-35-II b.)

Total – 15 bays (15 switch modules).

Provide the following functions:

- control:

  • Circuit-breakers

  • disconnertors, earthing blades (if operating mechanism is present, perspective)

-monitoring:

  • circuit-breakers, disconnectors, earthing blades

Switchgear-10 kV, the scheme “Three working busbars, sectioned by switches, with busbar coupler” including:

- 45 high-voltage circuit-breakers

- 2 SS, 1BC

- 5 feeders (1VT-10-I; 2VT-10-I; 1VT-10-II; 2VT-10-II; VT-10- III )

Total – 58 bays (47 switch modules).

Provide the following functions:

- control:

  • Circuit-breakers

  • trolleys, earthing blades (if operating mechanism is present, perspective)

- monitoring:

  • circuit-breakers, trolleys, earthing blades

Auxiliary subsystem and operating current subsystem:

To ensure the functions of processing signals collecting and SU control for:

- Auxiliary board 0.4 kV (not less than 60 outgoing feeders)

- DC board 220 V (not less than 35 outgoing feeders)

The exact number of connections to determine at runtime the working draft.

Microprocessor-based controllers, supplied as part of the technical means of DC board and auxiliary board, connect to the ACS TP using industry standard communication protocol Modbus.
