Abstract
Method of starting up a station of a high-voltage d-c transmission system having at least two converters which with current and voltage regulators are connectible to d-c and three-phase networks or power plants and are selectively operable as rectifiers and inverters, and for starting up the three-phase network or power plant connected to the station, the station at the start-up time, being isolated from a functioning three-phase network or power plant and auxiliary equipment required for the operation thereof, which includes feeding from the d-c side of the high-voltage d-c transmission system active power required for starting up the station of the high-voltage d-c transmission system, and feeding from an independent reactive-power source reactive commutation power required for the start-up operation of the station of the high-voltage d-c transmission system as well as other reactive power required during the start up.
