Individual facies unit has N number of valve tower, is N valve towers near DC side, common 6N on platform according to being No. 1 valve tower near AC
Valve tower, each valve tower is made up of several submodules.
By carrying out appropriate design to offshore platform, the capital equipment of above-mentioned MMC systems sea current conversion station is carried out rationally
Layout.It is illustrated in figure 2 offshore wind power flexible DC power transmission current conversion station three-dimensional overall schematic diagram.
Be divided into three layers for the flexible direct current transmission converter station offshore platform that offshore wind farm is sent, in Fig. 2 from top to bottom according to
It is secondary to be：Underlying platform, middle level platform and top layer platform, the compound steel structural construction mutual association composition offshore platform.Compound steel
Structural construction bottom is made up of deck some steel plates, and per 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 the height of converter valve cooling device room 3 compares connection transformation
Device room 2 is lower slightly, and the light current such as the first control device and auxiliary equipment area 4 area rooms height is lower.
The top layer platform of offshore platform is placed and is coupled transformator, converter valve cooling device and exchange access device；Middle level
The heavier equipment such as converter valve is mainly placed with underlying platform, middle level platform places bridge arm reactor, and underlying platform is placed straight
Stream reactor, direct current output equipment；And, every layer of platform is all provided with control device and auxiliary equipment area in identical position,
Whole offshore platform does not have the input and output of forceful electric power in light current region side.
It is illustrated in figure 3 offshore wind power flexible DC power transmission current conversion station offshore platform top layer platform device layout.
Top layer platform is divided into four function rooms, respectively：Exchange access device and auxiliary equipment area 1, are coupled and become
Depressor room 2, converter valve cooling device room 3 and the first control device and auxiliary equipment area 4.The electric energy of each wind field is by marine remittance
After collecting system collects, ac bus are linked into the exchange access device of offshore platform top layer and auxiliary equipment area 1, in the region
Also spark gap, transformer, switchgear and protection equipment etc..
Mainly place water cooling equipment, cold heat dissipation equipment of valve etc. in valve in converter valve cooling device room 3.It is easy to radiating positioned at top layer
Design, and, Caulis Piperis Kadsurae carries out greatly outer cold design on it can make full use of, and makes full use of the natural resources, and other equipment is affected
It is minimum.It is coupled in transformer room 2 for placing transformator and corresponding equipment, transformator adopts three single-phase transformer structures
