Ostbayernring
Line substations |
As Eastern Bavaria ring a 298 km long 380/220-kV is three-phase - free line connection in the Bavarian administrative districts of Upper Franconia , Upper Palatinate and Lower Bavaria referred to the substation of the power plant Irsching about Schwandorf , Etzenricht and Mechlenreuth to Redwitz leads. As part of the extra-high voltage network, it serves to supply the sparsely populated eastern part of Bavaria across the region.
history
The line was built by Bayernwerk between 1970 and 1975 and is laid continuously on Danube masts ; in the northern part between Redwitz and Etzenricht, 110 kV lines run in sections on an additional crossbeam on the same rod.
Originally, when it was built, it was equipped with two 220 kV circuits that were attached to the masts with vertical isolator chains. It was not until 1991 that a circuit was converted to 380 kV in the course of the new construction and renovation of the Bavarian high-voltage network after the reunification of Germany and the distinctive insulators were installed.
Since 1992, the Etzenricht substation has been connected to the Czech extra-high voltage network via a two-circuit 380 kV three-phase connection. Since the Czech power grid was not synchronized with the Western European grid until 1995, a direct current short coupling was set up on the substation area .
In 2000 Bayernwerk merged with PreussenElektra to form the new energy supplier E.ON Energie , which transferred its transmission network to the Dutch company TenneT in 2010 . Since then, the line has been owned by this company.
Isolators
The suspension of the 380 kV outer conductor on the pylons is characteristic of the line , with the inner conductor hanging on the lower cross member on an insulator, which in turn is attached to two V-shaped insulators. This type of fastening is used to ensure the minimum distance between the 380 kV system and the mast even in windy conditions. In the event of strong crosswinds, there would otherwise be the risk that this insulator, which is longer than the 220 kV system, could get too close to the earthed mast due to the relatively narrow cross-arm. With the parallel 220 kV system, this type of conductor suspension is not necessary due to the lower operating voltage and small safety distances.
New building
Since the current line regularly reaches its capacity limits due to the increasing feed-in of renewable energies, primarily from new wind farms in Upper Franconia and the Upper Palatinate, as well as the lack of larger power plants in the eastern Bavarian region, the 185 km long section between Redwitz and Schwandorf is to be built with a new building two 380 kV circuits are replaced. In the Federal Requirements Plan Act of 2013, the replacement of the line is included as measure No. 18. The regional planning procedure for this was completed at the end of 2016.
The project was included in the start network in the 2019–2030 network development plan .
Several citizens' groups have formed against the planned new construction of the overhead line. Requirements include laying underground cables or using so-called compact masts.
The plan approval procedure has been carried out in four stages since May 2018. TenneT organizes 'information markets' alongside the project for the affected population.
Section Redwitz - Mechlenreuth
The application for planning approval was submitted in the Redwitz - Mechlenreuth section on May 17, 2018. On January 27 and 28, 2020, there was a discussion meeting in the planning approval procedure for the Redwitz - Mechlenreuth section.
Mechlenreuth - District border Upper Franconia / Upper Palatinate
The application for planning approval was submitted in the section Mechlenreuth - District boundary Upper Franconia / Upper Palatinate on November 28, 2018. The completeness check in the section Mechlenreuth - district boundary was completed on April 18, 2019, and the participation process began in this section on April 10, 2019.
District border Upper Franconia / Upper Palatinate - Etzenricht
The application for planning approval was submitted in the section Upper Franconia / Upper Palatinate - Etzenricht district on November 29, 2018. The participation process in the Upper Franconian / Upper Palatinate - Etzenricht section began on May 6, 2019.
Etzenricht - Schwandorf section
The application for planning approval was submitted in the Etzenricht - Schwandorf section on June 29, 2018. The public hearing for the Etzenricht - Schwandorf section planned for March 30, 2020 was canceled due to the COVID-19 pandemic in Germany .
