The Rzeszów–Khmelnytskyi powerline is an electrical power transmission line between Ukraine and Poland. It is the only 750 kV-powerline in Poland and one of the few of it in the European Union of this type.
History
The decision to build this powerline was made in 1977 and it went in operation in 1985.[1] The line went out of service after Poland joined the synchronous grid of Continental Europe (UCTE).[2] However, there is a plan to re-activate this line after 2010 by constructing back-to-back station on the Polish end of the line. The first report on the back-to-back station was prepared already in 1995.[3]
Technical description
It has a length of 395 kilometres (245 mi), of which 281 kilometres (175 mi) in Ukraine and 114 kilometres (71 mi) in Poland.[1] It runs from Widełka substation near Rzeszów in Poland to Khmelnitskiy Nuclear Power Plant in Ukraine. It is the AC line, which has a single circuit. It can transfer a maximum power of 1300 MVA.
As pylons guyed portal pylons are used. Strainers are from special design. They consist of three free-standing lattice towers each carrying one conductor. Each strainer tower has a crossbar at which the conductor is led around the structure on a huge insulator.
The line crosses at 50°3′24″N 25°22′5″E / 50.05667°N 25.36806°E the 750 kV powerline from Zakhidnoukrainska Substation to Rivne Nuclear Power Plant, which may be the only crossing of two 750 kV powerlines in Europe.
