Equipment information:

Modular Packaged 35 kV Switchgears of RSN-35 series are equipped with withdrawable circuit breakers of VEP 40.5 type, Modular Packaged 6-10 kV Switchgears of RSN-10 series are equipped with withdrawable circuit breakers of VEP 12 series. Input panels are equipped with relay protection devices based on microprocessor unit F650 manufactured by GENERAL ELECTRIC. Protection and onload changing control panels of the transformer are based on protection units T35 manufactured by GENERAL ELECTRIC and Sirius 2 RN manufactured by ZAO Radius Avtomatica. Central alarm panels are based on BRESLER - 0107.050 unit. Central alarm box (CAB) is manufactured by OOO NPP Bresler.

Line differential protection panels of 35 kV and 10 kV are based on protection units L30 manufactured by General Electric. Differential bus protection panels are based on B30 protection unit manufactured by General Electric.

Equipment includes 2nd level automation system of supervision and technological control – telecontrol panels and automated commercial electricity metering system (ACEMS) panels. Connection to the 1st level of automated control system equipment (relay protection units) is implemented based on Ethernet (protocols IEC 60870-5- 104 and Modbus TCP/IP). Data connection with the upper-level system (control center) is implemented based on protocol IEC 60870-5-104. Industrial loud-speaker and alarm system DVS-21 are installed in telecontrol panels.

In addition to the main functions automated dispatch control system provides:

• organization of industrial control room and loudspeaker communication at SS and 35/10/6 kV SWG;
• data collection and processing from station engineering sub-systems (video monitoring, security and fire alarms and telephone communication) etc.;
• organization of connection to Distribution Company via radio relay communications with emergency satellite communication channel.

Automated dispatch control system of energy is made as a partition structure on the base of autonomous automated control systems of power supply of the 35/10/6 kV substations (switchgears) (11 spatially distributed objects) and has a three-level hierarchical structure. The first level includes relay protection IEDs and other protection devices, electric meters of SS and SWG, DCS of 0.4 kV electric equipment, utilities (control communication equipment, cameras, IP-phones etc.). The second level includes telecontrol panels (CC-TC), panel of automated commercial electricity metering system (CC-ACEMS) and data transferring equipment. The third level (control center) includes telecontrol, communication, ACEMS servers, AWS and data transfer equipment. Data collection from relay protection units and other intelligent electronic devices within one controlled section is made by telecontrol panel CC-TC by virtue of commutation equipment. CC-TC except DATD communication controller also includes industrial commutation switches and protocol bridges, routed networks and power supply units for panel equipment operation. TM panel is supplied with telecontrol server which allows to collect, process and accumulate data having HMI directly at the level of SS (SWG) to provide autonomous operation of objects automation system and power supply system. All electric power meters within one controlled unit are joined to the local network and connected to remote terminal unit of CC-ACEMS. Data exchange between CC-TC and CC-ACEMS, utilities located in controlled units and control center is carried out via fiber-optic communication line (FOCL). GSM communication line is provided as a spare line.

Start-up:

The full scope of supervision and commissioning works was completed. There were no claims on duration of works and their quality from the Customer. Act of acceptance was signed by State Acceptance Commission in November 19, 2015. Less than 1 year has passed between the delivery finish dates and putting into operation. This was facilitated by the following:

• Customer was interested in timely putting objects into operation;
• Customer’s confidence in professionalism, competence and reliability of Supplier;
