Description
Technical field
The present invention relates to the balancing technique of column type floating platform, particularly relate to the balancing technique of floating type reactor, namely column type floats the balanced system of nuclear reactor platform in balance device and formation thereof and balance method.
Background technology
Floating type reactor refers to the moveable nuclear reactor utilizing floating platform to build.Floating type reactor can be used for providing power, generates electricity, desalinizes seawater, heating, supply steam etc., the special requirement of off-lying sea, polar region or the region such as remote districts, isolated island heat, electricity, water, vapour coproduction can be met.
Only have a country of Russia building floating type nuclear power station KLT-40S at present in the world, be designed for the remote community energy supplies such as eastern Siberia, expectation will realize generating in 2016.The floating type nuclear power station that Russia builds 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, it adopts roll booster to provide the effect environmental forcess aboard ship such as opposing wind, wave, stream, thus on position ship being remained on as much as possible sea level requires, its location cost can not increase along with the depth of water and increase, and operation is also more convenient.First dynamic positioning system is supported to be applied in ship, pipeline and cable laying ship, scientific surveying ship, deep-sea lifeboat etc. at offshore drilling ship, platform, its cardinal principle utilizes computing machine to gathering the environmental parameter (stormy waves stream) of coming, according to the position that position reference system provides, automatically calculate, control the thrust size of each roll booster, make boats and ships keep the motionless of fore direction and accommodation.
The marine structure such as drilling platform, naval vessel often need to be located in marine certain a bit to carry out the various operations such as drilling well, salvaging, marine salvage, pipe laying, oceanographic survey, diving.In the past, mostly adopt the methods such as anchoring to position, the required construction project time was longer, and especially at deep-sea place, anchoring localization method exists larger difficulty.Along with the rapid emergence of Naval Architecture and Ocean Engineering, traditional positioning system can not meet the requirement of region, deep-sea positioning operation, and Ship Dynamic Positioning Systems Based can address this problem well.The dynamically positioning of boats and ships grew up gradually from the seventies, had important purposes in the field such as oceanographic engineering, scientific investigation.Comprise three subsystems: power system, thruster system and power-positioning control system.
Dynamic positioning system is a kind of control system of closed loop, when not by mooring system, constantly detect the physical location of boats and ships and the deviation of target location, the size that boats and ships of sening as an envoy to return to target location required thrust is calculated again according to the impact of the external disturbance power such as external wind, wave, stream, and thrust distribution is carried out to thruster each on boats and ships, each thruster is made to produce corresponding thrust, thus on position ship being remained on as much as possible sea level requires.Wherein power system provides energy to whole dynamically positioning, need promote turbine engine generating provide energy demand in floating nuclear power plant platform according to dynamically positioning technology by reactor heat production.
The limitation of above-mentioned background technology is as follows:
Due to traditional roll booster, be directly reverse to platform apply antagonism unrestrained flow path direction acting force, therefore along with the intensity of wave stream increases, the acting force so needing roll booster to export is also larger, therefore the power consumption of conventional alignment systems is large, therefore to there is energy demand large in traditional power location, power consumption is large, initial cost is large, maintenance cost is higher, and cost to be in line rising along with the tonnage size of boats and ships and platform, if estimate by the 200MWe floating platform of 50,000 tons, general generation about 50% electric power energy need for traditional power location above, and improve offshore floating power station cost about 30%.Although and conventional chains anchorage style good economy performance, also exist and the depth of water required that high, hull fixes the defect such as out of true and instability.And traditional platform and boats and ships cannot utilize the advantage of construction itself to overcome the impact of stormy waves stream.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind ofly to float the balance device of nuclear power platform and balanced system and balance method for column type floating platform or column type, can greatly reduce the energy resource consumption of balance device and balanced system.
