    摘要： In a method of series compensating rotating electric alternating current machines (2) connected, directly or via a static current converter (28), to a three-phase distribution or transmission network (6), wherein the stator winding of the alternating current machine is Y-connected, a capacitive circuit (14) for the fundamental frequency of the voltage is connected in each phase between the down side of the winding and the earth point (20) of the distribution or transmission network (6). A device for such series compensation comprises a capacitive circuit (14) for the fundamental frequency of the voltage, connected between the down side of the winding and the earth point (20) of the distribution or transmission network (6).

    摘要： The magnetic circuit of a generator in a wind power plant is arranged to directly supply a high supply voltage of 2-50 kV, preferably higher than 10 kV. The generator is provided with solid insulation and its winding includes a cable ( 6 ) comprising one or more current-carrying conductors ( 31 ) with a number of strands ( 36 ) surrounded by at least one outer and one inner semiconducting layer ( 34, 32 ) and intermediate insulating layers ( 33 ). The outer semiconducting layer ( 34 ) is at earth potential. The stator winding may be produced with full or fractional slot winding, the phases of the winding being Y-connected. The Y-point may be insulated and protected from over-voltage by means of surge arrestors, or else the Y-point may be earthed via a suppression filter. The invention also relates to a wind power plant, a generator included in the plant and a variable speed system for such a plant.

    摘要： In a plant comprising one or more electric machines constructed with insulated conductors and connected for heavy current via insulated conductors, the magnetic circuit in at least one of these electric machines is connected directly to a high supply voltage of 20 - 800 kV, preferably higher than 36 kV. The insulation of the electric machine is built up of a cable (6) placed in its winding and comprising one or more current-carrying conductors (31) with a number of strands (36) surrounded by outer and inner semiconducting layers (34, 32) and intermediate insulating layers (33). The conductors (31) may be group-wise connected in parallel and semiconducting layers are therefore not required around every conductor in the group. If the conductors (31) are connected in series with each other within the group a part insulation (35) is required which will withstand a few kV, whereas connection of the conductors (31) to every phase requires a strong part insulation (35) which will withstand the phase voltage of the high-voltage supply network.
