Abstract
The utility model discloses a kind of single-phase chain structure of STATCOM, including N group transverter side chains, from first group into N group transverter side chains transverter quantity increase one successively, each transverter is sequentially connected in series in each transverter side chain, transverter is in parallel with remaining transverter in adjacent transverter side chain in addition to first transverter in each transverter side chain, and IGBT pipes have been respectively connected to it on one of parallel wire between adjacent transverter side chain, also include control unit, current transformer, sampling unit, control unit is connected with the grid of each IGBT pipes, current transformer is connected by sampling unit with control unit.The utility model can improve the ability of shock resistance electric current, and improve the reactive-load compensation effect to power network.
Description
Technical field
Static compensator FIELD OF THE INVENTIONThe is the utility model is related to, specifically a kind of single-phase chain type knot of STATCOM
Structure.
Background technology
STATCOM（STATCOM）It is a kind of FACTS devices of parallel connection type reactive-load compensation, will can changes during use
Stream device cascades to form chain structure.Although the STATCOM of prior art chain structure can bear larger voltage,
In power network powered on moment flimsy problem is still suffered from by large impact electric current.
Utility model content the purpose of this utility model is to provide a kind of single-phase chain structure of STATCOM, with
Prior art chain structure STATCOM is solved due to the flimsy problem of excessive dash current.
In order to achieve the above object, technical scheme is used by the utility model：
A kind of single-phase chain structure of STATCOM, it is characterised in that：Including N group transverter side chains, wherein first
Group transverter side chain in have a transverter, from first group into N group transverter side chains transverter quantity increase one successively,
And each transverter is sequentially connected in series in each transverter side chain, has N number of transverter in N group transverter side chains, from first group
Transverter side chain rises, transverter and remaining in adjacent transverter side chain in addition to first transverter in each transverter side chain
Transverter is in parallel, and has been respectively connected to IGBT pipes between adjacent transverter side chain on one of parallel wire, and the IGBT pipes are logical
Cross own collector electrode, on the corresponding parallel wire of emitter stage access, first transverter and triple line be wherein in N group transverter side chains
One phase line is connected, in addition to control unit, current transformer, sampling unit, control unit are connected with the grid of each IGBT pipes,
In the corresponding phase line of current transformer access, and current transformer is connected with sampling unit input, sampling unit output end and control
Unit connection processed.
A kind of described single-phase chain structure of STATCOM, it is characterised in that：The transverter changes for voltage source
Flow device.
In the utility model, control unit by current transformer gather phase line on electric current, if in the presence of large impact electricity
During stream, control unit controls the IGBT pipes of respective numbers to turn on as needed, realizes the parallel connection of adjacent transverter side chain, Neng Gouti
The ability of high impact-resistant electric current.Managed simultaneously by the IGBT of varying number, the incrementally increase of access transverter quantity can be achieved,
The reactive-load compensation effect to power network can be improved.
Brief description of the drawings
Fig. 1 is the utility model topology diagram.
Embodiment
As shown in figure 1, a kind of single-phase chain structure of STATCOM, including three groups of transverter side chains, wherein first
There is a transverter 1 in group transverter side chain, transverter quantity increases one successively in transverter side chain from first group to the 3rd group
It is individual, and each transverter is sequentially connected in series in each transverter side chain, has three transverters in the 3rd group of transverter side chain, from the
One group of transverter side chain rises, in each transverter side chain transverter with adjacent transverter side chain in addition to first transverter
Remaining transverter is in parallel, and has been respectively connected to IGBT pipes 2, IGBT pipes 2 between adjacent transverter side chain on one of parallel wire
By on own collector electrode, the corresponding parallel wire of emitter stage access, in N group transverter side chains first transverter and triple line its
In a phase line 3 connect, in addition to control unit 4, current transformer 5, sampling unit 6, control unit 4 and each IGBT pipes 2
Grid is connected, and in the corresponding phase line 3 of the access of current transformer 5, and current transformer 5 is connected with the input of sampling unit 6, and sampling is single
First 6 output ends are connected with control unit 4.Transverter is voltage source converter.
