Definitions
- the invention relates to a device for reducing a magnetic flux 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 application area is basically included
- DC component can, for example, electronic
- Construction components come as they are today in the
- 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 excitement has a strong harmonic content and this is due to the
- Windings and iron parts of the transformer caused. This can lead to local overheating in the transformer. Furthermore, due to the strong excitation requirement, high reactive power consumption and voltage drop occur. Together, this can lead to the instability of the energy transmission network. Simplified speaking, the behaves the
- WO 2012/041368 AI is one in a
- DC ratio used 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
- Capacitor is connected in the neutral point of the transformer. This solution is problematic because the charging of the capacitor creates a transfer voltage. In addition, the displacement voltage across the capacitor is limited, so that usually not the entire DC current can be blocked. This solution is also problematic if there is a short circuit in the transmission network and therefore too
- Claim 1 is characterized in that
- a controllable current source is provided for feeding current into the compensating windings, which is electrically connected in
- Row is arranged with the compensation windings, with their neutral point, from the inputs of the
- a star point generator is provided which is electrically conductive with the outputs of the compensation windings
- Ampere turn is another term for the magnetic flux. It is the
- Compensation current introduced by a controllable current source in the compensation windings which is usually a compensation winding per phase of the 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. You can now easily insert a controllable current source between these star points. Furthermore, the
- 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. Due to the controllable power source is the
- Compensating current can be provided that 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.
- Such measuring devices are from the WO
- the shunt part may be connected to the core of the transformer e.g. be arranged adjacent to a leg or on the yoke to pass a portion of the magnetic flux in a bypass.
- Shunt-guided magnetic flux can be very easily a long-term stable by means of a sensor coil
- Gain sensor signal which optionally after signal processing the DC component (CD component) maps very well.
- the star point generator can be used for better load distribution
- Windings in zigzag circuit include.
- Figure 1 is a principle circuit according to the prior art for introducing compensation current in a
- FIG. 2 shows a basic circuit according to the invention for
- 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, but with a
- Thyristor T is controlled by a current limiting inductor L
- the controllable current source S is electrically connected directly in series with the compensation windings Kl, K2, K3, namely, the inputs of the compensation windings Kl, K2, K3 are interconnected in a star point PI, which is directly connected to the power source S.
- a compensation winding Kl, K2, K3 is on a leg of one - not here
- connection ends are each with a connection end of the three (here lower)
- Zigzag switching means that primary and secondary windings of a phase (here a compensation winding) on
- Primary and secondary windings of the neutral point H are the same size, so have about the same number of turns, but are flowed through in different directions from 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 directly on the one hand with the neutral point PI of the compensation windings Kl, K2, K3 and on the other hand with the neutral point P2 of the neutral point H electric
- Power source S be arranged.
- Neutral point generator H are known per se and available.
- the introduction of compensation windings with induced Voltages at the medium voltage level are in themselves also already proven technology.
- the advantage of the present invention is that the controllable current source
