Description
Technical field
The present invention relates to the balancing technique of column type floating platform, the balancing technique of more particularly to floating type reactor,
The i.e. balance system of column type floating nuclear reactor platform in balance device and its composition and balance method.
Background technology
Floating type reactor refers to the moveable nuclear reactor built using floating platform.Floating type reactor can be used for
There is provided power, generate electricity, desalinize seawater, heating, supply steam etc., the regions such as off-lying sea, polar region or remote districts, isolated island can be met
Heat, electricity, water, the special requirement of vapour coproduction.
An only Russian country builds floating type nuclear power station klt-40s in the world at present, is designed for west primary
The remote districts energy resource supply such as Leah east will be it is contemplated that will realize generating electricity in 2016.The floating type nuclear power station that Russia is built
It is mainly used in providing electric power and heat energy to solve the energy required for the Far East Area's natural resources exploitation.
Dynamic positioning system (dynamic positioning system) is a kind of control system of closed loop, and it is using helping
Thruster provides the effect environmental forces aboard ship such as opposing wind, wave, stream, so that ship is maintained at requirement on sea level as much as possible
On position, its positioning cost will not increase with the depth of water and increase, and operates also more convenient.Dynamic positioning system exists first
Offshore drilling ship, platform support that ship, pipeline and the aspect such as cable laying ship, scientific surveying ship, deep-sea lifeboat are applied, its
Cardinal principle is the ambient parameter (stormy waves stream) collection come using computer, the position being provided according to position reference system, from
Calculated dynamicly, controlled the thrust size of each boost motor, make ship keep the motionless of fore direction and accommodation.
The marine structures such as drilling platforms, naval vessel be frequently necessary to be located in marine certain point with carry out drilling well, salvaging,
The various operation such as marine salvage, pipe laying, oceanographic survey, diving.In the past, mostly positioned using methods such as anchorings, required
The construction project time is longer, and especially at deep-sea, anchoring localization method has larger difficulty.With Naval Architecture and Ocean Engineering
Rapid emergence, traditional alignment system can not meet the requirement of deep-sea region positioning operation, Ship Dynamic Positioning Systems Based
This problem can be solved well.The dynamic positioning of ship gradually grew up from the seventies, in ocean engineering, scientific investigation
There is important purposes in field.Including three subsystems: dynamical system, thruster system and power-positioning control system.
Dynamic positioning system is a kind of control system of closed loop, in the case of not by mooring system, constantly detects
Go out the physical location of ship and the deviation of target location, the impact further according to the external disturbance power such as external wind, wave, stream calculates
Make ship return to the size of target location required thrust, and thrust distribution is carried out to thruster each on ship, make each thrust
Device produces corresponding thrust, so that ship is maintained on the position require on sea level as much as possible.Wherein dynamical system be to
Whole dynamic positioning provides energy, need to be promoted by reactor heat production according to dynamic positioning technology in floating nuclear power plant platform
Turbogenerator generates electricity provides energy demand.
The limitation of above-mentioned background technology is as follows:
Due to traditional boost motor, it is the active force that directly inversely platform is applied with antagonism wave stream direction, therefore with wave
The intensity of stream increases, then need the active force of boost motor output also bigger, the power consumption of therefore conventional alignment systems is big, therefore
There is energy demand greatly in traditional power positioning, power consumption is big, and initial cost is big, and maintenance cost is higher, and cost is with ship and platform
Tonnage size be in line rising, if to estimate by 50,000 tons of 200mwe floating platform, probably produce 50% about electric power
Energy needs is used for traditional power and positions above, and improves offshore floating power station cost 30% about.And conventional chains anchorage style
Although good economy performance, exist the depth of water is had high demands, the hull fixation defect such as inaccurate and unstable.And traditional platform and ship
Oceangoing ship cannot overcome the impact of stormy waves stream using the advantage of construction itself.

In said structure, axle sleeve, position limited gear, rotating shaft constitute a rotating mechanism, and being disposed to of position limited gear is prevented
Only Eddy propeller body swings with ripple in wave, rely on the orientation position-limiting action of position limited gear so that Eddy propeller this
On certain direction, the overall structure that axle sleeve, position limited gear, stream propeller body are formed can carry out turning body around the shaft
Dynamic.Water (flow) direction according to wave and intensity, by changing the rotating speed size of Eddy propeller and the court of adjustment Eddy propeller
To realizing the stability of integral platform, for example, when column type floating platform forward direction receives the impact of wave, whirlpool can be adjusted
Flow angle of rake direction, and advance in backward direction, to realize resisting the impact of wave.By by outside positioner
The platform ocean coordinate of (generally station keeping radar) and underwater sensor collection and the environment such as ocean stormy waves stream uniform flow, intensity ginseng
Number, input computer is analyzed, and calculates and starts amount of force and the direction that each Eddy propeller needs, by power
Positioning control system carries out platform positioning accurate measurement, passes to the size and Orientation that dynamical system determines Eddy propeller, then
The system of commander's Eddy propeller operates it is ensured that the position of platform immobilizes.In order to cost-effective, typically float along column type
The turbine impeller of periphery arrangement one circle of platform, turbine impeller can realize high-speed rotation in the range of 180 degree.Then will
Anchor chain is connected to seabed, balances out the active force of most of stormy waves stream it is ensured that platform will not be pulled away using the effect of anchor chain.Borrow
Help the advantage of anchoring, under the cooperation of dynamic positioning system, the position of precise control platform.Using above-mentioned positioning mode, can drop
Low propeller separate unit power and size, effectively reduce energy consumption and cost, preferably reduce consumption when construction cost and day-to-day operation
Can ratio.
