Ultranet route sections
|
Ultranet is the name of a line project as high-voltage direct current transmission (HVDC) within the framework of the network development plan (NEP) of the Federal Republic of Germany. As a special feature, Ultranet is to be implemented as an overhead line and installed on masts of existing three-phase power lines. The project is carried out by the transmission system operators Amprion and TransnetBW and is to run between Osterath in North Rhine-Westphalia and Philippsburg in Baden-Württemberg .
requirement
Since the network development plan in 2012, the transmission system operators have been considering increasing the large-scale transmission capacity from North Rhine-Westphalia to the north-west of Baden-Württemberg. The network development plans 2013, 2014 and 2030 (versions 2017 and 2019) have updated and specified the considerations. The Federal Network Agency has confirmed the network development plans in each case. With the federal requirement plan law of 2013, the energy industry necessity and the urgent need u. a. determined by law by Ultranet. There is Ultranet the line construction project number. 2
Ultranet is listed by the European Commission as an internal German project of common interest under number 2.9 in the PCI list of the European Union.
Together with the HVDC line projects A-North forms Ultranet the so-called corridor A .
planning
The planned route is a joint project of the transmission network operators Amprion and TransnetBW and is to run over approx. 340 km between the network connection points Meerbusch - Osterath in North Rhine-Westphalia and Philippsburg in Baden-Württemberg. According to representatives of the Federal Network Agency , the background to the start of the route in Meerbusch is that the route will initially (at the latest until the phase-out from coal- fired power generation in Germany ) primarily be used to transport electricity from the lignite-fired power stations in the Rhenish lignite district , which is fed into the Osterath substation is intended for southern Germany. The independent line project A-North represents an extension of the route from Osterath to Emden .
Amprion estimated the investment costs for the Osterath - Philippsburg line in 2014 at EUR 1 billion, of which EUR 300–400 million would be for each of the two double converters.
Most of the conductor cables required for the Ultranet are installed on existing three-phase current lines , so there is hardly any need to erect additional masts or develop new lines.
Compared to the usual three-phase network, direct current transmission has significantly fewer losses in its course, but must be coupled to the three-phase network with special converters.
Federal planning
The federal sectoral planning provides for the creation of a spatial compatibility study (RVS) and the implementation of a strategic environmental assessment (SUP) as essential components. As a first step, the Federal Network Agency organizes one or more public application conferences as part of the federal technical planning, depending on the needs or complexity of the project.
Ultranet from Osterath to Philippsburg is procedurally divided into five sections.
| section | Federal states | Route length in km | status | |
|---|---|---|---|---|
| C. | Osterath - Rommerskirchen | North Rhine-Westphalia | 30th | Discussion meetings have taken place |
| E. | Rommerskirchen - Weißenthurm | North Rhine-Westphalia, Rhineland-Palatinate | 100 | Application documents have been submitted |
| D. | Weißenthurm - Riedstadt | Rhineland-Palatinate, Hesse | 110 | Discussion meetings have taken place |
| A1 | Point Ried - Point Wallstadt | Hesse, Baden-Wuerttemberg | 28 | Route corridor decided |
| B1 | Point Wallstadt - Philippsburg | Baden-Württemberg | 40 | Route corridor decided |
Plan approval procedure
After completion of the federal technical planning , the plan approval procedure can be applied for by the network operator, within the framework of which the exact routes and the technical design are bindingly approved. The competent authority is the Federal Network Agency, which involves the bodies responsible for public affairs as well as associations (including nature conservation organizations ) and affected private individuals.
| section | status | |
|---|---|---|
| A1 | Point Ried - Point Wallstadt | Application conference took place |
| B1 | Point Wallstadt - Philippsburg | Application conference took place |
converter
The transmission capacity of Ultranet is to be 2000 megawatts with an operating voltage of 380 kilovolts . Within the three-phase network , the lines of which can be interconnected as required, current-controlled high-voltage direct current transmission is limited to transmission between two points. At these points, it requires technically complex power converter stations (power converters, converters) that establish the connection to the three-phase network. Meshing is only possible with voltage-controlled converter stations. These are required at all end points and can usually not be combined with current-controlled converters.
Osterath location
Philippsburg location
For the southern converter, which is also around 10 hectares in size, TransnetBW has chosen a location on the site of the Philippsburg NPP . Following an application from June 2018, the Karlsruhe District Office granted approval for the construction and operation of the direct current transformer station in March 2020 on the basis of the Federal Immission Control Act. The substation can be built on the nuclear power plant site after the cooling towers have been blown up.
