Brief description
The band casing converter valve components structural representation that Fig. 1 is linked in sequence for a kind of HVDC converter substation of this utility model
Figure.
Specific embodiment
With reference to each accompanying drawing, describe the structure of this utility model HVDC converter substation and operation principle and its excellent in detail
Gesture.
HVDC converter substation of the present utility model, from traditional lcc-hvdc escalation process, can effectively again
Taken up an area using alternating current filter and shnt capacitor, therefore, effectively saved the cost of upgrading.
One common vsc-hvdc current conversion station includes converter power transformer, exchanges reactance, converter valve, DC filter.Logical
Often converter power transformer and exchange reactance are out of doors, and converter valve and DC filter are then placed in the valve Room.It is logical between them
Cross wall bushing to couple together.
The HVDC converter substation that this utility model provides, including converter power transformer, exchange reactance and DC filter.Phase
For existing vsc-hvdc, it includes multiple converter valve components with casing being linked in sequence, as shown in figure 1, each converter valve
Assembly is placed in a casing 10.Each converter valve components 15 includes multiple conversion modules being connected in series.Multiple orders connect
The converter valve components 15 with casing connecing, the outfan of the previous converter valve components 15 with casing, after sleeve pipe 14 connects
The input of the converter valve components 15 with casing for one, the face, but whole converter valve components with casing do not form closed loop even
Connect.
HVDC converter substation of the present utility model, the input of each converter valve components is all connected to casing itself, from
And greatly reduce potential voltage difference between each conversion module and box house.Secondly, each casing is arranged on
In insulating carriage/support platform, therefore, each casing and converter valve components distance from the ground is still very high.
According to a most preferred embodiment of the present utility model, each valve body is placed in a casing, with reduce from
The electrical Interference of whole HVDC converter substation, the input and output side of each casing is sequentially connected, and the input of each valve group
End and casing connect to reduce the voltage difference between valve group module and casing.Each casing is placed on an insulated platform,
And between insulated platform/bracing frame and the earth, employ insulator isolation 11.
HVDC converter substation operation principle of the present utility model is as follows:
The main task of HVDC converter substation is that alternating current is converted into DC current, is then conveyed by transmission line
To another current conversion station of far-end, it is then converted to alternating current.Wherein converter valve is the core component of current conversion station, and voltage source commutation valve is adopted
Realize AC-DC conversion with power electronic element.The converter valve of most of DC engineerings is to design within doors, is placed using hanging type,
So contribute to waterproof, dust-proof and shockproof.The scheme of the design is outdoor console model scheme, places to realize preventing using casing
Water, dust-proof.And the mode of small-sized many casings series connection can meet the shockproof demand of converter valve.
