Outdoor Switchyards of the Chernobyl NPP

 outdoor switchgear  Add category
110 kV, 330 kV, and 750 kV outdoor switchyards were designed to transmit power generated by the Chernobyl Nuclear Power Plant to the power grid. After the plant's permanent shutdown, they have been used to facilitate electricity transit between different power systems within Ukraine's unified energy system, provide power output from Khmelnytskyi NPP, supply electricity to Belarus, and transfer energy from main grids to Kyivoblenergo networks. The switchyards also supply power to consumers in areas adjacent to the plant and meet the auxiliary power needs of the Chernobyl NPP.

  • this is a power grid right?
  • >this is a power grid right? yep
  • It's a substation, DC power output is converted to AC, sent to another substation, stepped down and used to light up homes.
  • i thought that generators made AC currents and batteries made DC currents ps i did't know they could be converted?
  • I'm sure that the generators give an AC output... just remember: the AC current has a sine curve... sine is trigonometry... rotation, rotation, rotation....
  • 1ST UNIT in 1996 or 2nd Unit in 1991
  • AFAIK last reactor was stopped in 2000.
  • 3rd Unit worked until 5th December 2000 when it was stopped because of security system malfunction. It was started again on the 14th December at 5% and 15 December 2000, 13:17, on the orders of the President of Ukraine during the broadcast teleconference Chernobyl "nuclear power plant <-> the National Palace "Ukraine", by turning the emergency protection key (AS-5) reactor unit number 3 in Chernobyl Nuclear Plant was shut down permanently and the station ceased electricity generation.
  • Don't forget, nuclear power plants require large amounts of EXTERNAL power to operate. They have diesel backups but they are for emergencies only. Thus, these plants needed twice as many transmission lines, one set of AC going in to power the motors (needing to be stepped down to DC) and one set going out (DC needing to be stepped up to AC). For 6 reactors, that makes for a LOT of wires and transformers and explains the size of the switching yard.
  • The Chernobyl substation is very much alive, and a major part of the 750-kV cross-country transmission line to northern Ukraine from the Khmelnytsky Nuclear Power Plant. The switchgear in this substation is controlled from a room on the +10m elevation in Phase 1 of the power plant. And, as others have said, the station itself is a consumer of electricity taken from this substation, needing the power to cool spent fuel and operate other critical equipment.
