From December 2019, # ZaĆogaEltelNetworks has been modernizing the 400/220/110 kV Dunowo power station. We have left only SOT to be performed, i.e. the Technical Protection System. Up to now, we have done, among others:
- construction design and formal and legal documentation, obtaining the final building permit and all other decisions and permits necessary for the investment
- executive project
- construction and assembly works (adaptation of rooms), reconstruction of the existing control room (battery room, communication room)
- construction of a station for the AT3 transformer (access bench, bowl, foundation) - ready to be put in AT
- primary and secondary circuits (disassembly, temporary connections, construction of foundations and structures for apparatus, busbars, delivery and assembly of primary and secondary apparatus, commissioning)
- commissioning and control and measurement works in field 6 (R110 kV) requiring cooperation with a wind farm
- purchase and delivery of MiCOM P139 security devices
- general substation systems, including: development and adaptation of automation and general substation systems of 400 kV switching stations, synchronization, electricity measurement systems, circular circuits, cable connections, lightning protection, earthing of the station - to the extent necessary to start AT3 and PPN
- telecommunications with 48 V power supply - installation of devices and cabling in the power station area
- civil engineering works: roads, cable ducts, fire wall, micro-leveling, area lighting, rainwater drainage, drainage of AT stand, oil separator, valve kiosk, sprinkler installation, water intake
Congrats and thanks to our brigades and everyone involved for a great job!
