THREE ENERGY UNITS OF THE BURSHTYN TPP WILL OPERATE FOR THE UKRAINIAN ENERGY SYSTEM FOR THE FIRST TIME IN 15 YEARS
For the first time in almost 16 years, given the working conditions of the Ukrainian energy system (the temperature dropped to 18 degrees below zero), three energy units of the Butshtyn TPP, namely the 8th, 9th and the 11th operated for the Ukrainian energy system. It meant that up to 200 MW were added to cover the peak loads.
Let`s take a historical journey into the “Burshtyn Energy Island”: the The Burshtyn power station was disconnected from the national grid in 2002 to form the Burshtyn Energy Island, which was further connected to the European network of transmission system operators (former UCTE, now ENTSO-E). The operational scheme stipulated for the functioning of two energy units of the Burshtyn TPP (namely №8 and №9) both for the “island” grid and the main part of the Ukrainian energy system grid.
Almost two years ago, in August, 2015, the Cabinet of Ministers of Ukraine ordered to take measures as regards to refixturing of three energy units (10th, 11th and 12th) of the Burshtyn TPP so that they function within the Ukrainian energy system. The engineering solution was to be developed by the DTEK specialists however that was not unfortunately done.
Afterwards, owing the difficult balancing working conditions of the Ukrainian energy system, the specialists of the NPC “SE “Ukrenergo” offered the technical solution as regards to additional switching of the other unit (unit №11) for the operation both within the “Burshtyn TPP Island” grid and the Ukrainian energy system grid.
On the 5th of May 2017 the following technical solution was approved; as well, the necessary work to implement the technical measures was performed at the power station in order to ensure the switching. The activities included reconstruction of the protection and replacement of the primary wiring.
After the physical changes at the open-air switchgear of the Burshtyn TPP were executed, Ukenergo hold a meeting with PSE S.A., the Polish TSO, as regards to alignment of the corresponding changes in the operational activity of the “Island”. The changes were mutually agreed by the parties.
“We will commission three energy units of the Burshtyn TPP for the main part of the Ukrainian energy system again in case of the absolute balancing provision of the “Burshtyn TPP Island”, commented Vitalii Zaichenko, Deputy CEO, Chief Dispatcher at Ukrenergo.
