New natural-gas cavern storage facility in the Netherlands: Siemens supplies variable-speed electric drives for gas compressors
Erlangen, 2007-04-19
The Siemens Industrial Solutions and Services (I&S) Group has received an order from MAN TURBO AG, Switzerland, to supply five variable-speed electric drive systems for the Zuidwending underground natural-gas storage facility in the Netherlands. The final customer is a joint venture of the companies N.V. Nederlandse Gasunie and Nuon BV. The volume of the project amounts to around 10 million euros and the gas storage facility is scheduled to start operating in 2010.
Nederlandse Gasunie buys, transports and sells natural gas and promotes its safe, efficient and innovative use. In the Netherlands, the company has a pipeline network with a total length of around 11,600 kilometers. Nuon is a leading energy supply company which serves customers in the Netherlands, Belgium and Germany with electricity, gas, heat and supplementary services.
Together, the two companies are currently building a natural-gas storage facility in underground salt caverns near Zuidwending in the Groningen province. The gas storage facility is to have a capacity of around 180 million cubic meters and is mainly intended to work as a buffer and compensate for peaks in demand. Located 1,000 to 1,500 meters below the surface, the caverns are connected to the national gas supply network in the Netherlands by means of a short pipeline. The caverns are filled with the help of gas compressors which can feed in up to 1.2 million cubic meters of natural gas per hour.
For operation of the gas compressors, Siemens is supplying five variable-speed drive systems of the type “Sisog Comp D”, each with an output of 12 megawatts. The drive units consist of water-cooled converter-fed induction motors and “Perfect Harmony” medium-voltage converters, including the associated open-loop and closed-loop control technology. In addition, Siemens will supervise installation and commission the electric drive systems.
