particularities
	Two spatially separated plant areas, test area for high voltage technology

The Mannheim-Rheinau substation is a large substation in the German state of Baden-Württemberg and is located east of Mannheim between the districts of Rheinau and Friedrichsfeld . It consists of two spatially separated plant areas that are operated by Amprion and Netze BW .

The facility built in the 1920s with the construction of the north-south line by RWE and Badenwerk was and is due to its central location in the transmission network and the proximity to the cable and wire works in Neckarau as a test site for new developments from the Used in the field of high voltage technology.

location

The facility is located northeast of the eponymous district of Rheinau, from which it is separated by the A 6 that runs directly west of the site , on the edge of the Dossenwald (also known as the Rheinau Forest ).

Immediately to the west of the RWE site is the site of the Research Association for Electrical Systems and Power Management , which has its headquarters here, and the Rheinau waterworks and a game reserve are in the immediate vicinity.

The Mannheim substation to the east, which is located on the Mannheim – Basel railway line , is also fed with electricity from the Mannheim power station, but is not directly related to the substation.

history

The construction of the substation is related to the large Mannheim power plant, which was founded in 1921 and has been producing electricity as a joint power plant since 1923 . One of the operators was the Badische Landes-Elektrizitätsversorgung Karlsruhe , operating under the name Badenwerk from 1938 , which maintained a network of overhead lines in Baden that was just emerging. The question of feeding in electricity from the Mannheim power plant therefore arose.

The architect Karl Wilhelm Ochs was then commissioned to design a switch house. The first designs date back to 1925, but it wasn't until 1927 that Brown, Boveri & Cie. , which had an important location in Mannheim-Käfertal , with the construction of the switch house. A special feature of the structure was the roof entry of the 110 kV lines.

The substation then became an important hub in the electricity supplier's network, which runs from Rheinau to the Scheibenhardt station near Karlsruhe , where the Rudolf Fettweis plant near Forbach was connected with a 110 kV line, via Offenburg to Laufenburg an der Schweizer Border extended. The connection from Scheibenhardt to Laufenburg was completed in 1926, and from 1931 there was also a further 110 kV line between Offenburg and Strasbourg connected to the Alsatian power grid. There was a connection to the high-voltage network of the Pfalzwerke via Ludwigshafen .

When the first big step towards a nationwide high-voltage network was taken in the 1920s with the construction of the north-south line, RWE chose Rheinau as the location for a 220 kV transformer station, also in order to be connected with the large Mannheim power station and the operating companies. Thus, the transmission network now connected the Mannheim power plant location with the Rhenish-Westphalian industrial areas and the hydropower plants in the Alps and in the southern Black Forest.

In the 1950s, tests by the 400 kV research association, founded in 1950, took place on the substation's premises, in preparation for the introduction of a 380 kV transmission network in Germany. Since the power plants in the Rhineland and Westphalia produced more and more electricity, the capacity of the 220 kV lines used up to now was no longer sufficient. The test facility consisted of a 2 km long 380 kV test line and a station in the Dossenwald. The experience gained through this system was taken into account during the construction of the first 380 kV line in Germany between Rommerskirchen and Hoheneck , which has been running past the substation parallel to the north-south line since 1957.

Before ABB maintained an overhead line mast testing facility in Mannheim-Mallau from 1959 , Rheinau served as a test site for the German Association of German Association (DVG) for overhead line masts.

After the study society for high-voltage systems, which had been based in Rheinau since 1967, merged with the 400-kV research community to form the research community for high-voltage and high-current technology on January 1, 1973, Rheinau became the seat of the association, where tests have continued to be carried out on its own test site ever since.

The old switch house is no longer in operation today and is empty, but has been preserved for monument protection reasons.

technical structure

The substation consists of two spatially adjacent, but separate plant areas, with the RWE area to the north being considerably larger than the one to the south that was built by the Badenwerk. The former comprises the voltage levels 110 and 220 kV, between which the voltage is converted using two transformers, the latter today only consists of a 110 kV switchgear. The brick building from the 1920s, which is now vacant, is directly adjacent to the site. Although the plant areas are right next to each other, there is no direct overhead line connection between them.
