Definitions
- the invention relates to a device for switching direct currents
- DC currents in one pole of a DC network encompass ⁇ send two terminals, between which extends an operating current path with a mechanical switch which can be bridged by a Abschaltzweig, wherein in the Abschaltzweig a power switching unit is arranged, which is a series circuit of two-pole submodules with at least one power semiconductor switch which can be switched on and off, and wherein commutation means are provided for commutating the current from the operating current path to the turn-off branch.
- the invention further relates to a method for switching direct currents with such a device.
- a device of the type mentioned at the outset is known from the publication by J. Häfner and B. Jacobson "Proactive Hybrid HVDC Breakers - A Key Innovation for Reliable HVDC Grids", symposium “The Electric Power System of the Future - Integrating Super-Grids and Micro-Grids International Symposium ", Bologna, Italy, 13.-15. September 2011, page 264 ff. And WO 2011/057675 AI known.
- the described therein ⁇ DC voltage switch has an operating current path with a me chanical ⁇ switch and a Abschaltzweig which is connected to the operating current path parallel.
- a series circuit of power semiconductor scarf ⁇ tern is arranged, each of which a freewheeling diode is connected in parallel in opposite directions.
- the consisting of power semiconductor switch and freewheeling diode switching units are antise ⁇ riell arranged, the turn-off cruschlei- terschalter are arranged in series and for each power semiconductor switch ⁇ a corresponding power semiconductor switch is provided with opposite passage direction. In this way, the current in both streams can be interrupted in the turn-off branch.
- an electronic auxiliary switch is arranged in series with the mechanical switch in addition to the mechanical switch.
- the switch is shorted. The arc goes out.
- the run on the power semiconductor switch current can be by appropriate control of the power semiconductor un ⁇ interrupted.
- a DC voltage circuit breaker which can be integrated serially in a DC voltage line. It consists of a series connection of power semiconductor switches which can be switched on and off, to each of which an opposite freewheeling diode is connected in parallel. Wei ⁇ terhin is parallel to each power semiconductor switch a Abieiter, for example, a varistor, connected to the voltage limit.
- the previously known DC voltage switch is designed purely electronic and thus switches considerably faster compared to commercially available mechanical switches. Within a few microseconds, a short-circuit current flowing via the DC voltage switch can be interrupted. The disadvantage, however, is that the operating current must also be conducted via the power semiconductor switches. This results in high transmission losses.
- WO 2011/141055 discloses a DC voltage switch which can be serially connected in one pole of a high voltage direct current network.
- the DC-DC switch comprises a mechanical switch in series with a power semiconductor switch to which an opposite Freilaufdio ⁇ de is connected in parallel again.
- Parallel to the series circuit of power semiconductor switch and mechanical switch are a series circuit of coil and capacitor, ie an LC branch and a Abieiter, connected, which limits the voltage drop across the LC branch voltage.
- the power semi-conductor switches ⁇ a Abieiter is connected in parallel. After opening the mechanical switch of hoschlei ⁇ terschalter is switched with the natural frequency of the LC branch and off. As a result, a vibration and finally a current zero crossing is generated in the mechanical switch, so that the resulting arc can be deleted.
- the object of the invention is to provide a device and a method of the type mentioned, with which fault currents can be safely interrupted in a DC voltage network, at the same time low passage losses are generated.
- the invention solves this problem with regard to the device in that the commutation means is arranged in the turn-off branch and for generating a current flowing over the bridged section of the operating current path and the turn-off branch
- the invention also achieves this object with a method in which a current sensor detects the current flow in the operating current path to obtain current measured values, a control unit connected to the current sensor monitors the current measured values for the presence of an intervention criterion and, when the intervention criterion is present, controls the commutation means, that such a large circulating current is generated that the current flow is limited via the mechanical switch to a maximum current.
- the commutation means are no longer arranged in the operating current path, in contrast to the above-mentioned closest prior art. Therefore, the commu ⁇ t istsstoff not act as passive commutator, which interrupt the operating current path.
- the commu ⁇ t istsstoff which actively generates a reverse voltage in a mesh formed by the turn-off branch and the portion of the operating current path bridged thereby.
- the the be ⁇ said mesh imposed reverse voltage drives one over the mechanical switch lead circuit current, which is opposite to the switching current.
- the two opposite currents cancel each other out in the ideal case.
- With equal currents in the operating path the current in the mechanical switch is almost zero. In other words, the current is conducted almost completely across the turn-off branch by the active commutation means. Subsequently, the mecha ⁇ African switch open almost normally. If the mechanical switch is opened in the operating current path, the power switching unit can limit ⁇ Abschaltzweig in the current and / or completely broken.
- the configuration of the power switching unit is fundamentally arbitrary within the scope of the invention. This also applies to the commutation means. However, it is essential that the ex ⁇ switching branch forms a higher electrical resistance than the bridged from him part of the operating current path. In addition, the sub-modules of the power switching unit able to switch off the high short-circuit currents safely and beyond kontrol ⁇ profiled reduce this energy released.
- the commutation means are designed in such a way that they generate such a high circulating current in the time window that the current flow is suppressed via the mechanical switch and that current can then be opened without current. For detecting the current flow in Be ⁇ drive current path, a current sensor is provided.
- the commutation ⁇ medium include not only the current sensor is advantageously a control and / or regulation unit which is connected to the current measuring sensor ⁇ the operating current path.
- the current readings produced by the current ⁇ measuring sensor are transmitted to the regulation unit, which evaluates the received current measurement values to determine whether a previously defined intervention criterion exists.
- intervention criterion is for example an excessive increase in current (di / dt) or if the measured current values exceed a current threshold a pre ⁇ specified time window long.
- any linkages with further measured values of protective devices or the like or further criteria are possible within the scope of the invention. If such an intervention criterion exists, the said circulating current is generated so that the rising short-circuit current commutates into the turn-off branch. If the mechanical switch is opened, the current can be limited by the sub-modules, or if necessary also Switch ⁇ on. In the context of the invention, it is also possible borrowed that the mechanical switch is opened only over a limited period of time, for example, if a Be ⁇ influence of the current flowing over the entire device current is desired.
