Since the first introduction in the Siemens FACTS portfolio several synchronous condenser solutions have been in operation.
Siemens installed three 60-MVAr synchronous condensers at the Georgia Black Sea HVDC station in June 2012. This synchronous condenser solution will support the transmission network between Georgia and Turkey with the required short-circuit power in order to operate the newly installed HVDC back-to-back station.
In Denmark, Siemens has delivered a 250-MVAr synchronous condenser solution that will start operation in summer 2013, providing the transmission system with a short-circuit power of more than 800 MVA in addition to reactive power control. The installation of this standalone synchronous condenser solution will enable the transmission system operator Energinet.dk to operate the transmission network without the need for a large thermal power plant. This makes the installation an economically and environmentally advantageous investment enabling the infeed of large amounts of renewable energy into the transmission network.
