Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in further detail.
Offshore wind power flexible DC power transmission converter station offshore platform embodiment of the invention:
MMC system wiring figure is sent out as shown in Figure 1 for offshore wind farm.Offshore wind farm sends out MMC system and uses symmetrical monopolar
(pseudo- bipolar) topological structure, can effectively reduce change of current station equipment and offshore platform area, have preferable economy.
MMC system sea converter station capital equipment includes: to be coupled transformer, bridge arm reactor, converter valve, direct current reactance
The cooling equipment of device, converter valve, control system equipment and corresponding switch and protection equipment.Wherein converter valve is the master of offshore platform
Equipment is wanted, the change of current function in converter station is completed by 6 phase elements, and each phase element is made of several valve towers.Wherein, often
A phase element has N number of valve tower, is N valve tower close to DC side, total 6N on platform according to being No. 1 valve tower close to exchange side
Valve tower, each valve tower are made of several submodules.
By rationally designing to offshore platform, it is reasonable that the capital equipment of above-mentioned MMC system sea converter station is carried out
Layout.It is illustrated in figure 2 offshore wind power flexible DC power transmission converter station three-dimensional general illustration.
For offshore wind farm send out flexible direct current transmission converter station offshore platform be divided into three layers, in Fig. 2 from top to bottom according to
It is secondary are as follows: underlying platform, middle layer platform and top layer platform, the compound steel structural construction mutual association form offshore platform.Compound steel
Structural construction bottom is made of deck several steel plates, and every layer of steel structure platform is all divided into multiple function rooms, each
Function room is designed as different height according to equipment.As shown in Fig. 2, cooling 3 height of canyon of converter valve is compared to connection transformation
Device room 2 is slightly lower, and the light current area rooms height such as the first control equipment and ancillary equipment area 4 is lower.
The top layer platform of offshore platform, which is placed, is coupled the cooling equipment of transformer, converter valve and exchange access device；Middle layer
The heavier equipment of converter valve grade ratio is mainly placed with underlying platform, middle layer platform places bridge arm reactor, and underlying platform is placed straight
Flow reactor, direct current output equipment；Moreover, every layer of platform is all provided with control equipment and ancillary equipment area in identical position,
Entire offshore platform does not have outputting and inputting for forceful electric power in light current region side.
It is illustrated in figure 3 offshore wind power flexible DC power transmission converter station offshore platform top layer platform device layout.
Top layer platform is divided into four function rooms, is respectively as follows: exchange access device and ancillary equipment area 1, is coupled and becomes
Depressor room 2, the cooling canyon 3 of converter valve and the first control equipment and ancillary equipment area 4.The electric energy of each wind field is converged by marine
After collecting system collects, ac bus is linked into exchange access device and the ancillary equipment area 1 of offshore platform top layer, in the region
There are also arrester, mutual inductor, switchgear and protection equipment etc..
The cooling canyon 3 of converter valve mainly places water cooling equipment, cold heat dissipation equipment of valve etc. in valve.Positioned at top layer convenient for heat dissipation
Design moreover, making full use of the natural resources that can make full use of cold design outside the big progress of upper sea wind, and influences other equipment
It is minimum.It is coupled in transformer room 2 for placing transformer and corresponding equipment, transformer uses three single-phase transformer structures
At, transformer net side ac bus enters by casing from exchange access device and ancillary equipment area 1 and is coupled transformer room 2,
Transformer valve side bus is linked into downwards middle layer platform by casing.Wherein, it is coupled transformer room 2 using the material convenient for heat dissipation
Material, and sufficiently sea wind carries out heat dissipation design later.
It is illustrated in figure 4 offshore wind power flexible DC power transmission converter station offshore platform middle layer platform device layout.
Middle layer platform is divided into three function rooms, is respectively as follows: bridge arm reactor room 5, front end valve hall 6 and the second control equipment
With ancillary equipment area 7.It is the exchange of six phase elements by its three-phase bus-tapping after valve side ac bus enters bridge arm reactor
Then side inlet wire is linked into bridge arm reactor exchange side input terminal.
It is illustrated in figure 5 offshore wind power flexible DC power transmission converter station offshore platform underlying platform device layout figure.
Underlying platform is divided into five function rooms, is respectively as follows: third control equipment and ancillary equipment area 12, rear end valve hall
11, positive DC reactor room 8, negative DC reactor room 9 and dc switch and output equipment area 10.
Since converter valve quantity is relatively more in large capacity MMC system, two valve halls are at sea designed in platform: in being located at
The front end valve hall 6 and rear end valve hall 11 positioned at underlying platform of layer platform.Front end valve hall 6 is connected with bridge arm reactor room 5.Valve hall
Middle converter valve is arranged according to six phase element modes of connection, bridge arm reactor room 5 draw six roots of sensation bus by casing into
Enter front end valve hall 6, front end valve hall 6 draws six roots of sensation bus in the position close to DC side, and it is flat to be linked into bottom downwards by casing
Platform.Two DC bus drawn from rear end valve hall 11 respectively enter positive and negative direct current reactor room and are connected with direct current reactor.Directly
Stream switch and output equipment area mainly place DC side arrester, switchgear, measuring device and relevant direct current and pick out
Equipment etc..Valve hall is divided into front end valve hall and rear end valve hall according to topological structure by the platform, effectively reduces the face of offshore platform
Product.
Valve tower design is as follows in specific valve hall:
When the quantity of valve tower on each bridge arm is even number, the quantity of valve tower is equal in front end valve hall and rear end valve hall.Example
Such as: as N=6, totally 36 valve towers on platform are located at middle layer wherein 1~No. 3 valve tower of each bridge arm is located at front end valve hall
Platform；4~No. 6 valve towers of each bridge arm are located at rear end valve hall, that is, are located at underlying platform.3 No. 6 valve tower end phases of upper bridge arm
Company forms positive electrode bus, and 3 No. 6 valve tower ends of lower bridge arm are connected to form negative electrode bus.
When the quantity of valve tower on each bridge arm is odd number, in order to reduce offshore platform area, it can make front end valve hall with after
The valve tower quantity in the end valve Room is close as far as possible.Such as: as N=5, totally 30 valve towers on platform, wherein 1~No. 2 of each bridge arm
Valve tower is located at front end valve hall, that is, is located at middle layer platform；3~No. 5 valve towers of each bridge arm are located at rear end valve hall, i.e., flat positioned at bottom
Platform.3 No. 5 valve tower ends of upper bridge arm are connected to form positive electrode bus, and 3 No. 5 valve tower ends of lower bridge arm are connected to form cathode
Bus.
It is all provided with control equipment and ancillary equipment area, i.e. light current area in the same position of each floor, entire platform is weak
Electric area does not have outputting and inputting for forceful electric power, is easily installed debugging and maintenance；It can also be improved the utilization rate in space.
The platform can be with integral hoisting to offshore platform, and the biggish equipment of weight is designed in bottom steel building
In, it is easily installed and transports.
