Branch of the Unified Energy System System Operator (UES) The Joint Dispatching Department of the North-West Energy System (UDE of the North-West) has developed and implemented a set of routine measures for testing and commissioning the new 330 kV Narva substation.
The EEC announced this on January 29, 2025.
The 330 kV Narva substation is located in the village. Ust-Luga, Leningrad region, the substation was energized at the end of December 2024.
As part of the substation project:
complete switchgears have been installed and put into operation 330 and 110 kV with the installation of 4 autotransformers with a capacity of 400 MVA each,
a new 330 kV overhead line Kingisepp — Narva No. 2 was built and put into operation.,
The existing Koporskaya — Kingisepp overhead line was divided to form 2 new 330 kV Koporskaya — Narva and Kingisepp — Narva No. 1 overhead lines.
The Narva substation construction project was implemented by EnergoSK. The new substation is equipped with digital technology for remote control of switching devices and grounding disconnectors from the control center of the ODU of the North-West. The Narva substation will provide technological connection to the
networks of large gas processing and gas chemical complexes (GPC and GCK) under construction in the ethane-containing gas processing complex (KPEG) in the village. Ust-Luga, Leningrad region, with a planned consumption load of up to 795 MW.
We have performed the following types of work:
Supply of RPA cabinets for the protection of 330 kV lines based on Siprotec 5 series terminals of the company Siemens:
Overhead line 330 kV Koporskaya – Narva:
— 1 set of remote control units with KSS;
— 2 sets of remote control units with remote control units;
— a set of KZS.
330 kV overhead line Kingisepp – Narva No. 1:
— 1 set of remote control units with KSS;
— 2 sets of remote control units with remote control units.
The equipment was delivered to the facility in October 2023.
Development of a Digsi project for RPA devices;
Parameterization of RPA devices;
Checking the circuits of terminals interacting with each other and with the automated control system
Conducting comprehensive tests, inspections and trials.
Commissioning of protections when setting the 330 kV overhead line under operating voltage.
The NDP complex was completed from November to December 2024.
It is important to note that at the «reverse ends» of the 750 kV Koporskaya substation and 330 kV Kingisepp substation, Siprotec 4 series RPA terminals are installed. To implement the remote control function and the command/signal reception function, work was carried out on the compatibility of Siprotec 5 series 7SL87 microprocessor devices and Siprotec 4 series 7SD52 microprocessor devices..
