The digital substation is the most important link in the power supply system of the petrochemical complex.  WAMSs appear at the substations in order to increase the efficiency of dispatching control of power system modes. WAMS includes ENIP-2 PMU, Phasor Data Concentrator ES-PDC, WAMS’ diagnostics subsystem, subsystem of guaranteed power supply. The unified time system is based on the time synch module ENCS-2 for receiving signals of global navigation systems (GPS, GLONASS).

The 500 kV substation provides electricity to residents of the special economic zone, large enterprises of the chemical and petrochemical industry. In accordance to TSO requirements, the following equipment is installed at the substation for integration into WAMS: ENIP-2 PMUs, phasor data concentrator ES-PDC, and time synchronization module ENCS-2. The project was launched in 2016.

Support substation is an electrical substation which carries out the remote control of other substations. The substation is one of the support substations of the Leningrad Region. It served previously to supply electricity to a machine-building plant. Power supply of the nearby town is carried out from this substation. WAMS of the substation includes ENIP-2 PMU – 2 pcs, ES-PDC,- 1 pc. as well as indicating panel ENMI-6 to diagnose the state of WAMS elements. The subsystem of time synchronization is based on time synch module ENCS-2.

It’s the second largest hydroelectric power station on the Far East of Russia. The station reservoir is of great flood protection importance for the nearest settlements. The hydroelectric station has the highest buttress dam in Russia, as well as the most powerful diagonal hydraulic turbines. The installed capacity of the power plant is 1330 MW, the average annual electricity generation is 4910 million kWh. ENIP-2 PMUs are installed on 500 kV outgoing lines from which ES-PDC collects data. Time synchronization is carried out by ENCS-2. Panel of indication ENMI-6 shows the parameters of the diagnostics of system elements.

It’s the most powerful condensation thermal power plant in Bashkortostan. The plant was designed and constructed with the aim of using local high-sulfur oil as fuel. Installed capacity makes 1830 MW. ENIP-2 PMUs are installed to monitor operating mode of 6 generators and 3 departing lines of 500 kV. Input/output modules of analogue signals ENMV-3 are installed to control activation parameters of each generator. ES-PDC collects vector data and transmits it to the upper layer. Time synchronization is carried out by ENCS-2. Panel of indication ENMI-6 shows the parameters of the diagnostics of system elements.

Modern power plant with efficient combined cycle of heat and electricity production is one of the most efficient thermal plants in the region. 100% of the fuel balance of the station is a natural gas. Electric power makes 593 MW, thermal power makes 1307 MW. The operation of 4 generators and 6 220 kV outgoing lines is monitored by ENIP-2 PMU: data from the devices are transmitted to ES-PDC. Input/output modules of analogue signals ENMV-3 are installed to control activation parameters of each generator. ES-PDC collects vector data and transmits it to the upper layer. Time synchronization is carried out by ENCS-2. Panel of indication ENMI-6.

The power station started its functioning in 1930 according to the plan of electrification of Russia. But if fact, in 2015-2017 a new steam-gas power station was built. Today, the power plant is the largest steam-gas CHP in the Urals. Electric power is 757.5 MW, thermal power is 842.7 MW. ENIP-2 PMUs are installed to monitor operating mode of 6 generators and 4 departing lines of 220 kV. Input/output modules of analogue signals ENMV-3 are installed to control activation parameters of each generator. ES-PDC collects vector data and transmits it to the upper layer. Time synchronization is carried out by ENCS-2. Panel of indication ENMI-6 shows the parameters of the diagnostics of system elements.
