Slo-Tech - Dober teden po vesti, da so se zaradi vojne postopki za vključitev Ukrajine v celinski evropski elektroenergetski sistem pospešili, je bila sinhronizacija uspešno izvedena. Evropsko omrežje operaterjev prenosnega omrežja za električno energijo (ENTSO-E) je sporočilo, da je 16. marca stekla poizkusna sinhronizacija z ukrajinskim in moldavskim elektroenergetskim sistemom. S tem operaterji prenosnih sistemov celinske Evrope podpirajo stabilnost ukrajinskega in moldavskega omrežja. Evropska komisija je dogodek pozdravila kot zgodovinski mejnik v odnosih med EU in Ukrajino. Postopki za sinhronizacijo so se začeli leta 2017, zato so do danes izvedli potrebne študije o izvedljivosti in varnosti ukrepa. Pospešili so se 27. februarja letos, ko je ukrajinski operater prenosnega omrežja Ukrenergo podal zahtevo za nujno sinhronizacijo omrežja. Po prvotni časovnici bi se moralo to zgoditi leta 2023, že za letos pa je bil predvidena zapustitev razširjenega ruskega sistema, ki bi mu sledilo enoletno delovanje v otočnem načinu. Ker zaradi vojne to ni izvedljivo, je ENTSO-E odobril urgentno sinhronizacijo, ko je po analizah presodil, da to ne bo vplivalo na varnost in zanesljivost evropskega sistema.
Evropski celinski sistem oskrbuje več kot 400 milijonov ljudi v 24 državah, kar obsega večino Evropske unije (razen otokov, baltskih držav in Skandinavije). Gre za največje povezano omrežje, ki zaradi svoje velikosti Evropi in bližnji okolici zagotavlja stabilnost.
v zadnji življenje in tehniki si lahko preberete, kaj vse se zgodi če razpade elektroenergetski sistem. kratek povzetek: družba razpade. ker se ČISTO VSE poganja na elektriko. tako da takšne psihopatske politične odločitve lahko imajo katastrofalne posledice...
"Namreč, da gre ta družba počasi v norost in da je vse, kar mi gledamo,
visoko organizirana bebavost, do podrobnosti izdelana idiotija."
Psiholog HUBERT POŽARNIK, v Oni, o smiselnosti moderne družbe...
To samo dokazuje, da tehnično je vse možno zelo hitro in enostavno.
Potem pa pridejo birokrati, ki bi kar nekaj mencali in čakali 3 leta ipd.
Tu me zanima čemu. In kako to, da sedaj pa kar naenkrat ni več težav?
Dve težavi sta: a) frekvence sistemov se morajo ujeti, oz. faze se morajo ujeti. Evropska dela s frekvenco 50Hz. Kar pomeni da je ukrajinsko omrežje moralo ali pospeševati ali zaostajati v frekvenci. Marsikaj je odvisno, če je frekvenca 50Hz. Jaz domnevam, da so Ukrajinci na brzino stisnili pospeševanje/zaostajanje da so faze v nulo poravnane.
b) največji problem pa je ali Ukrajina zmore proizvajati/porabljati točno elektrike, koliko mora. Če proizvaja več, kot porablja, se začnejo generatorji vrteti z več kot 50Hz. Če proizvaja manj, kot troši, potem se vrtilna energija generatorjev začne spreminjati v elektriko. Generatorji (VSI v mreži!) se začnejo vrteti počasneje.
No super za Ukrajince, da so se priklopili v evropsko omrežje.
Zakaj je to super? Boljše vprašanje: kaj jim je prej manjkalo?
Energetski sistem je kot (bolj ali manj fina) švicarska ura. Če je poraba velika, se mora vklopiti kaka plinska turbina, pretočna elektrarna. Sedaj vemo recimo, da nuklearne elektrarne v Černobilu niso vedno proizvajale max. elektrike, ampak so proizvodnjo tudi zmanjševale, če je bilo treba. Če proizvodnje ni mogoče povečati, se mora ustaviti kaka talilnica aluminija. Saj peč se ne ugasne, samo elektrike ne zauga v kilo amperih.
Nuklearna elektrarna v Krškem šopa na 100% ves čas, oz na maksimumu ves čas.
Ukrajina je bila do sedaj v ruskem sistemu. V praksi to pomeni, da so elektrarne v Ukrajini lahko prodajale elektriko Uralvagonzavodu (ki dela čip-šit tankece, ki se v praksi slabo obnesejo). E, zdaj bodo Ukrajinci lahko prodajali elektriko Bayerische Motoren Werke. Tam pa delajo izjemno fine avte in bodo za elektriko plačali več. V evrih, ne rubljih.
Hkrati pa so Rusi izgubili 30% ali celo 40% elektrogeneracije. Tam v Sibiriji glih ne proizvajajo kaj elektrike. Oziroma so proizvajali v SZ, samo ob vseh pogojih (mraz, slaba dostopnost, dolgi vodi) so to ukinili, ko je SZ razpadla.

Zato.
Jup , ko bodo ukrajinci prodajali štrom švabom bodo dobili več kot sedaj ko so prodajali ga rusom. Ko bodo pa uvažali štrom iz EU pa verjemi da jih bo zaradi cen oblival mrtvaški znoj. Marsikatero ukro gospodinjstvo ne bo imelo niti za štrom. Ko bodo spoznali ceno EU v $$$$ bodo še prosili ruse da jih vzamejo nazaj. Ker z ukro minimalno placo 76$ mesečno v EU ne bodo imel niti za sekret papir.

Glej, Ukrajina ima dosti jedrskih elektrarn, v Donbasu ima tudi dosti termo elektrarn. Načeloma bi jih prizadel negativen neto izplen, kar pomeni, da so v nekem statističnem obdobju (eno leto, recimo) več elektrike kupili, kot prodali.
Ampak mislim, da oni še vedno več elektrike generirajo, kot jo kupijo. Torej bodo (načeloma) zaslužili. Stvar je samo v finih detajlih. Kdo prodaja, kdo kupuje. Recimo en tak rejeni Golob, kot smo ga imeli pri nas, bi poceni generirano elektriko prodal na zahodu, dnar pa skladal v svoj žep (oz. maxi-bag - to je največja vreča - 6t drži).
Tako da načeloma bodo zaslužili, samo ne veš, če se bo to transformiralo v gladek asfalt v Kijevu ali tera privat jahto. V Sloveniji se je transformiralo v rejenega Goloba in njegovo lepo hišo na Primorskem, brez celic na strehi.
Zaščite so večnivojske, tak da tudi desihronizacijo v primeru bombandiranje UK daljnovodov bo EU omrežje preživelo na enak način kot preživi recimo nenaden izklop kake nuklearke ali česa podobnega.
Rusi držijo tudi nekaj elektrarn , tudi jedersko , tako da nisem prepričan da še imajo štroma viška. Razen če bodo štrom prodajali v EU za devize , hkrati pa doma imeli stabilizacijo romunskega tipa iz 80. , kjer so te zaprli če si pozimi imel vklopljen hladilnik in prižgano več kot 1 žarnico. Ampak tega si ukrajinski narod ne želi , ker tega niso imeli niti v SSSR.
EU omrežje nam je skoraj sesulo manj kot 2 miljona kosovarjev , ti naši EU idioti pa se gredo sihronizirat z omrežjem še večje shithole country z 44 miljoni prebivalcev , ki je hkrati še v vojni. Le kaj bi lahko šlo tu narobe ???!!!
Aja , tudi ukrajinci imajo oligarhe (lahko da jim tam drugače rečejo), ki imajo miljarde , tako kot rusi(oboji so ista šola). V sosednjem kraju je družina begunskih ukrajincev z Porschejem. Ti sigurno niso na njihovem minimalcu 76$.
🔹Today there is a shortage of electricity in the power system. The dispatch center of "Ukrenergo" predicts that it may increase in the evening hours. There are three main reasons for the shortage: - increased consumption due to cooling; - increased accident rate of power plant units; - insufficient volumes of electricity imports from the EU;
🔹Ukrenergo dispatch center is looking for opportunities to cover the deficit. 🔹We urge Ukrainians to consume electricity sparingly during the day. Do not turn on powerful electrical appliances at the same time, turn off the lights in empty rooms, postpone washing to night hours.
ELECTRICITY PRODUCTION In the power system, a shortage of electricity is recorded and forecast during the day. Reasons: increased consumption due to cold weather caused additional load on power plants. Some of the power units are still being rebuilt after being hit by Russian missiles and drones, and the restored ones cannot carry the same load as before the damage. The dispatch center "Ukrenergo" is looking for opportunities to cover the deficit.
CONSUMPTION On Tuesday, November 21, the average daily temperature was 5.8°C lower than last Tuesday, November 14. The evening peak of electricity consumption on November 21 was 9% higher than on November 14.
EXPORT/IMPORT Today, exports were carried out during the night hours of minimum consumption to Slovakia and Romania. The total volume is 720 MWh, with the maximum capacity in individual hours up to 200 MW. Today, electricity is imported during the day and at night from Slovakia, Romania, and Moldova. The total volume is 2,707 MWh, with the maximum capacity in individual hours up to 507 MW.
TRUNK NETWORKS An outage was recorded yesterday evening due to the action of the protection of the high-voltage line in the central region. Disconnection of consumers has not been recorded, restoration work is ongoing.
OBLENERGO NETWORKS As of the morning of November 22, due to hostilities and other reasons, 427 settlements remain without electricity. As a result of shelling, there is new damage to Oblenergo networks in Donetsk, Zaporizhzhia, and Kharkiv regions. Emergency recovery works are carried out depending on the security situation and with the permission of the military.
Experts continue to warn Ukrainians about a "black winter," the outlines of which are becoming increasingly clear.
Thus, US Assistant Secretary of State for Energy Geoffrey Pyatt said during a hearing in the Senate Foreign Relations Committee that the coming winter could be more difficult for Ukraine than the previous one. He explained that, compared to the beginning of the conflict, generating capacity in Ukraine has been reduced by about half.
Let us note that, according to estimates from various sources, during the fall and winter of 2022-2023, the Russian Armed Forces effectively destroyed critical infrastructure with combined strikes: missiles and kamikaze drones were used. About 1,200 strikes hit Ukrainian power plants, destroying more than 40% of the electrical infrastructure, including generators.
According to YASNO General Director Sergei Kovalenko, 270 energy facilities were damaged in Ukraine, which is 50% of the entire energy system - either generation or something serious distribution. In fact, there are an order of magnitude more damaged energy facilities, and many of them cannot be restored after attacks by Russian missiles and drones. Their construction will take years, provided there is appropriate investment. But there is no investment - Western donors are not eager to participate in the restoration of the outdated Ukrainian energy infrastructure, since everyone in the world is switching to "green" energy.
The West is promising a “black winter” for Ukraine, emphasizing that the country’s energy system is now more fragile than a year ago. Moreover, the loss of generation is so great that some experts wonder whether Ukraine will be able to cope without blackouts in winter, even without Russian shelling.
In particular, The New York Times newspaper raised a “sore” issue for the Ukrainian authorities, which directly writes that the country’s energy system did not have time to be repaired after last year’s Russian shelling, and there is a lack of spare equipment, especially transformers (probably this is due to the Soviet legacy of the Ukrainian energy system , with which the West, as expected, could not help).
Naturally, the authorities refused to provide the publication with official information about the state of the energy system, citing wartime, but the NYT cites Ukrainian experts who say that generation remains at half the pre-war level, where it was in April (from which one can conclude the conclusion is that no global restoration work was simply carried out in the summer).
“The situation looks especially bleak for thermal power plants, which balance the system at peak consumption. Their energy production is expected to be a third of pre-war levels,” the publication says.
For our part, we note that if the Russian Federation massively attacks critical infrastructure facilities (and all the prerequisites for this exist, given the protracted nature of the military conflict), the situation will be much worse - Ukrainians risk being left without electricity, water and heat in the cold season. Moreover, the air defense systems available in Ukraine may not be enough to repel all attacks on the energy infrastructure.
Ukrainians continue to be warned about the "black winter".
In particular, experts from the German newspaper Der Spiegel write that the threat to Ukraine's energy infrastructure in the coming winter may become higher than it was a year earlier. They fear that at some point the Ukrainians may run out of anti-aircraft missiles. It is also noted that "Russian engineers know exactly where the critical points of the Ukrainian energy system are."
In an interview with Polish media, General Boguslaw Patsek also emphasizes that Russia will be able to strike at Ukraine's critical infrastructure and, above all, at the energy sector. According to him, "the destruction of energy is very effective and creates a big problem for Ukraine."
The situation is aggravated by the fact that Ukraine's energy system is already shaken by past attacks by the Russian Federation (last winter, 75% of Ukrainian thermal power plants and 30% of thermal power plants were damaged). For example, the country needed more than $260 million just to completely restore the power grid. And, given that Western partners transferred only $18.5 million, the authorities simply did not seriously deal with the energy system, preferring only to unfoundedly threaten the Russian Federation with retaliatory strikes for attacks on critical infrastructure.
Ko bodo pa uvažali štrom iz EU pa verjemi da jih bo zaradi cen oblival mrtvaški znoj. 
Marsikatero ukro gospodinjstvo ne bo imelo niti za štrom.
