Abstract: An electric network for generation and transmission of electric power has a power generating part (1), a point of common connection (PCC) for the power generating part, a transmission link (T, W, CAB), a load network (LN), and a reactive power compensating means (2, 2'). The transmission link is coupled between the point of common connection and a grid connection point (PGC) at the load network, and the reactive power compensating means is coupled to transmission link. The power generating part comprises at least one wind turbine (111) with an electric generator (113) of induction type, coupled to the point of common connection, and the reactive power compensating means comprises a capacitor bank (21) and in parallel coupling to said capacitor bank a controllable inductor (22). The inductor has a magnetic core (221), a main winding (222) for alternating current, and a DC-control winding (223) for direct current (Id), said DC-control winding for control of the magnetic flux set up by the main winding via orthogonal magnetization of the core.

Abstract: PCT No. PCT/SE97/00802 Sec. 371 Date Nov. 12, 1998 Sec. 102(e) Date Nov. 12, 1998 PCT Filed May 16, 1997 PCT Pub. No. WO97/44795 PCT Pub. Date Nov. 27, 1997A controllable inductor comprises at least a tubular core, a main winding (1) surrounding the core and a control winding (3) passing substantially axially through the core. It is adapted for connection to a three phase alternating current network and has for this sake for each phase (14-16) a main winding (1) for connection to the phase, a core and a control winding, and the control windings of the three phases are electrically connected in series to each other.

Abstract: An electric switching device for alternating current comprises two branches ( 2, 3 ) connected in parallel in a current path and having each at least two contact members ( 4-7 ) connected in series. A semiconductor device ( 8 ) is adapted to interconnect the midpoints between the two contact members of each branch. When opening the current path a first contact member ( 5 ) of one, first branch located before said midpoint as seen in the current direction existing is controlled to open and a second contact member ( 6 ) of the second branch located after the midpoint as seen in the current direction is controlled to open for transferring the current to a temporary current path through the semiconductor device. The current path through the switching device is then broken when the semiconductor device is in a blocking state by opening a contact member ( 4, 7 ) of the switching device arranged in the temporary current path.
