Definitions

  • the invention is based on a converter transformer according to the preamble of patent claim 1.
  • Figures 19.4 and 19.5 show three and four winding transformers of a high-voltage direct current transmission system, hereinafter referred to as HGU, in which one or two secondary windings of the transformer are connected to alternating current inputs of converters.
  • a tertiary or equalization winding is connected to filter suction circuits for harmonic currents or to generators, which supply the required reactive power for the converter.
  • the converters of an HGU generate harmonic currents. If these flow freely into the three-phase network, voltage distortions arise there. To prevent this, filter circuits (suction circuits) are connected to the three-phase busbar in parallel with the converter transformers. These filter circuits are dimensioned so that they have a very low impedance for certain dominant harmonics and thus form a short-circuit path for the harmonic currents.
  • the effect is that the harmonic currents flow predominantly into the filter circuits and thus the harmonic load on the network is kept low.
  • the filter circuits have very high specific costs. To reduce this, the filter circuits are connected to an additional winding of the converter transformers, which are dimensioned for a low voltage. The residual impedance of the compensating winding, which detunes the filter circuits and thus reduces their effect, is disruptive.
  • the invention solves the problem of achieving better filtering of disturbing harmonic currents which are generated by consumers, in particular by converters, by simple measures.
  • An advantage of the invention is that harmonic voltages are reduced in the AC networks and thus inadmissible distortions of the mains voltage and telephone interference are avoided.
  • an additional choke can be connected between the compensating winding and the filter circuit, so that it is not detuned.
  • the choke of the filter suction circuits of the filter circuit connected to the converter transformer can advantageously be dimensioned such that the additional choke is omitted.
  • the use of a 4-winding transformer for 12-pulse converter operation is particularly advantageous, in which the filter circuit essentially only has to be designed for filtering out the 11th and 13th harmonic.
  • A denotes a 400 kV three-phase network and B denotes a 220 kV three-phase network, which is connected to the three-phase network A via an HGU.
  • Converter transformers T A and T B transform the voltages present in the three-phase networks A and B in converters S 1 , S 2 and S 3 , S 4 to a value of 50 kV suitable for the DC coupling.
  • the converters S 1 and S 2 on the transmission side work as rectifiers; they take active power from the three-phase network A and transfer it to the DC side.
  • the converters S 3 and S 4 on the receiving side work as inverters; they take over the direct current power transmitted by the direct current line and deliver it to the three-phase network B as active power.
  • At least one smoothing choke L is provided in the DC circuit.
  • the converter transformers T A and T B each have a primary or high-voltage winding 1, two secondary or valve windings 2, 3 and a tertiary or balancing winding 4.
  • the primary windings 1 of the converter transformers T A and T B are connected to the respective three-phase network A or B connected, the secondary windings 2 or 3 to the AC inputs of the converters S 1 or S 2 and S 3 or S 4 .
  • the two compensation windings 4 are also connected to a filter circuit 6 '.
  • Two or more converter transformers with valve and filter circuits can also be connected in parallel per converter station.
  • the compensation windings 4 of the converter transformers can then be connected to one another. Due to the symmetrical structure, the transmitting and receiving sides can be interchanged.
  • FIG. 2 The winding arrangement of the cylinder windings of the converter transformers T A , T B according to FIG. 1 for an alternating current phase can be seen from FIG. 2.
  • a primary winding 1 or 1 ' Around each leg of a transformer core 5 there is a primary winding 1 or 1 'as the outer winding, a secondary winding 2 or 3 as the inner winding and a compensating winding 4 or 4 "between the outer and inner winding.
  • the two primary windings 1 and 1' are connected in parallel, the two compensating windings 4 and 4 "are connected in series and the two secondary windings 2 and 3 are made separately.
  • the arrangement on two legs keeps the undesired magnetic coupling of the secondary windings 2 and 3 as low as possible.
  • FIG. 3 An associated equivalent reactance circuit diagram for an AC phase is shown in FIG. 3, in which X 1 ⁇ X 4 denote equivalent reactances, which are assigned to the windings 1 ... 4 of the converter transformer T A or T B , and Xp, X fictitious Filter coupling reactances are.
  • the dimensions of the windings of the converter transformer and their spacing from one another are to be selected such that the filter-side equivalent reactance X 4 becomes 0.
  • Transformer Engineering (a publication of the General Electric Company's engineers of the transformer engineering department), edited by LF Blume, Wiley, New York (1938) p. 122 and 123.
  • a winding arrangement of the cylinder windings is for an AC phase 4 can be seen.
  • a compensating winding 4 ', a secondary winding 2, a further compensating winding 4 and a primary winding 1 are arranged from the inside to the outside around a transformer core 5' shown in sections.
  • the two compensating windings 4 and 4 ' are connected in series.
  • 8 denotes a consumer which is connected to the secondary winding 2 via the converter S 1 .
  • the filter circuit 6 is connected to the compensating winding 4 via the additional choke 7.
  • X 12 , X 24 and X 14 denote scattering reactances that can be determined in a known manner from measurements on the transformer between windings 1, 2 and 4 and are usually indicated on the nameplate of the transformer. Otherwise, the same parts are provided with the same reference numerals in all the figures.
  • the winding 3 must be dimensioned again so that the substitute reactance X 4 takes the value 0 or a small negative value.
  • an air choke with a (positive) reactance which is the same size as the negative equivalent reactance X 4 , is then connected in series with the compensating winding 4 and, if appropriate, 4 ' Bring to zero and the filter effect is fully retained.
  • X 4 can be calculated according to:
  • the secondary windings 3 with connected converters S 2 and S 4 are omitted.
  • the inner compensating winding 4 ' can be omitted and the required condition for the substitute reactance X 4 can be achieved only with the compensating winding 4 by suitably adjusting the spacings of the windings.
  • two compensating windings 4 and 4 ′ with the same number of turns are preferably used.
  • the invention is not limited to 3 or 4 winding transformers.
  • the two winding arrangements can also be arranged on one leg below one another instead of on two legs.
