Definitions

  • the invention relates to a device for reducing a magnetic DC component in the core of a transformer, in particular a three-phase transformer, comprising a plurality of compensation windings, which are magnetically coupled to the core of the transformer.
  • the field of application is basically both in transformers in the low or medium voltage range, as well as in transformers of very high power (power transformers, HVDC (high voltage DC transmission) transformers).
  • HVDC high voltage DC transmission
  • DC supply hereinafter also referred to as DC component
  • DC component may for example come from electronic components, such as those used today in the control of electrical drives or in the reactive power compensation.
  • GIC Geomagnetically Induced Currents
  • Geomagnetically induced currents occur approximately in ten-year cycles. They are evenly distributed over all (three) phases, can reach up to 30 A per phase and flow through the neutral point of a transformer. This leads to a strong saturation of the core of the transformer in a half cycle and therefore to a strong excitation current in a half cycle. This additional excitation has a strong harmonic content and thus caused by the stray field with harmonic content eddy current losses in windings and iron parts of the transformer.
  • a voltage induced in a compensation winding is used and used for the compensation of the disturbing magnetic DC component by a thyristor switch is connected in series with a current limiting reactor to introduce the compensation current in the compensation winding.
  • This solution works well for DC currents to be compensated within a range which are smaller by an order of magnitude than geomagnetically induced currents, ie in the range below 10 A.
  • geomagnetically induced currents one would have to go to the medium voltage level, ie in the range of approximately 5 kV, and use powerful thyristors. Due to the high power dissipation of such thyristors, this solution is not economical.
  • WO 2012/041367 A1 discloses an arrangement for reducing a DC field component in the core of a transformer, comprising a compensation winding magnetically coupled to the core of the transformer and a DC generator arranged in series with the compensation winding and with a reactance dipole, the reactance dipole comprising a parallel connection of an inductor and a capacitor is formed to feed into the compensation winding a compensation current whose effect is directed to the DC field component in the core opposite, wherein the inductance is formed of a first winding which is magnetically coupled to a second winding, the first winding with its one end connected to the DC generator and the other end connected to the compensation winding, and the second winding connected in parallel with the capacitor.
  • the principle of the solution according to the invention is again based on the DC compensation by means of compensation windings, in that targeted current is fed into the compensation windings, the effect of which is directed counter to the DC component and prevents the magnetization of the core of the transformer.
  • so-called Jacobamperewindungen be introduced into the transformer, ampere-turn is another term for the magnetic flux.
  • the compensation current is introduced by a controllable current source in the compensation windings, wherein a compensation winding is usually provided per phase of the transformer.
  • the problem of the voltages induced in the compensation windings must be solved.
  • a known star point generator which is also referred to as zero point or grounding transformer.
  • the neutral point generator generates a star point with respect to the outer conductor voltages of the compensation windings.
  • the star point of the compensation windings and the star point formed by the neutral point generator are at the same potential.
  • the star point generator has the advantage that direct currents that are introduced via its neutral point and then distribute evenly on all (three) of its legs, cause no magnetization of the core of the neutral point.
  • An embodiment of the invention provides that at least one current limiting inductor is arranged electrically in series with the current source. This pre-switching of a current limiting choke can effectively filter out transient voltages so that they do not break through to the power source.
  • the controllable current source is connected to a measuring device for detecting the magnetic DC component in the transformer.
  • a measuring device for detecting the magnetic DC component in the transformer are approximately from the WO 2012/041368 A1 in the form of a magnetic shunt part with a sensor coil.
  • the shunt portion may be disposed adjacent the core of the transformer, for example, on a leg or yoke to bypass a portion of the magnetic flux. From this, guided in the shunt magnetic flux can be obtained by means of a sensor coil very easily a long-term stable sensor signal, which optionally after a signal processing the DC component (CD component) maps very well.
  • the star point former may comprise zigzag windings for better load distribution.
  • direct current is deliberately introduced into a compensation winding K in order to eliminate the DC magnetization of the transformer core.
  • the alternating voltage induced in the compensation winding K is utilized; the compensation winding K acts like an AC voltage source.
  • the compensation winding K designed as a thyristor switching unit T is connected in series with a current limiting inductor L.
  • the required direct current can be adjusted by voltage synchronous ignition at a specific ignition timing of the thyristor T.
  • Ignition of the thyristor in the voltage zero crossing so sets the maximum direct current, which is superimposed with an alternating current of the amplitude of the direct current and the mains frequency. If the thyristor T is ignited later, the direct current becomes smaller, but also harmonic alternating currents occur.
  • the current flow in the thyristor T is limited by a current limiting inductor L, dimensioning for the current limiting is the permissible thermal load of the thyristor T.
  • the controllable current source S is electrically connected directly in series with the compensation windings K1, K2, K3, namely, the inputs of the compensation windings K1, K2, K3 are interconnected in a neutral point P1, which is directly connected to the power source S.
  • a compensation winding K1, K2, K3 is arranged on a leg of a - not shown here - three-phase transformer.
  • the three (here upper) primary windings with their one terminal end are each connected to an output of a compensation winding K1, K2, K3.
  • the other terminal ends are each connected to a terminal end of the three (here lower) secondary windings in zigzag connection.
  • the other terminal ends of the secondary winding are combined together in an artificial star point P2, which is connected directly to the controllable current source S.
  • Zigzag switching means that the primary and secondary windings of one phase (here a compensation winding) are arranged on different legs of the neutral point former H or that the windings on the same leg belong to different phases (different compensation windings).
  • Primary and secondary windings of the neutral point H are the same size, so have about the same number of turns, but are traversed in different directions by the stream. Thus, no flux is induced in the core of the neutral point H at the same current in different windings.
  • the current source S is electrically connected on the one hand directly to the neutral point P1 of the compensation windings K1, K2, K3 and on the other hand to the star point P2 of the neutral point generator H.
  • a current limiting inductor L may be arranged electrically in series with the current source S.
  • the controllable current source is at ground potential. You can go with the medium voltage level to 10 kV, 20 kV or 30 kV. This reduces the DC compensation current and you can work with commercial power sources.
  • the star point generator is very insensitive to star point DC currents, as they divide evenly and cause no additional nuclear magnetization.
