Description

Offshore wind energy resource addressing new technology
Technical field
The present invention constructs the new standard of a set of wind energy resources grade zoning (i.e. addressing), which can consider to provide comprehensively Source feature and environmental characteristic also can preferably show the region of wind energy grade than traditional scheme closer in Practical Project demand Sex differernce belongs to ocean new energy development and utilizes field, is mainly used in offshore wind farm, the both macro and micro of sea water desalination selects Location.
Background technology
Developing and using for offshore wind energy resource can make positive tribute to alleviate crisis of resource, the environmental crisis of human society It offers, or outlying island provides supply of electric power, improves its survival ability, the capability of sustainable development, enhancing human development sea The ability in ocean.The islands and reefs as many jewels are inlayed on boundless sea, these islands and reefs also will be maritime rights and interests maintenance, " 21 generation The critical support point that discipline Maritime Silk Road " is built.But it is many far from continent, electric power and water supply anxiety, ecology fragility etc. Difficulty seriously restricts survival ability, the capability of sustainable development on outlying island, is also always a worldwide difficulty for a long time Topic.In the electrified current era of height, without electricity, many equipment can not operate, or even paralysis.Sea turn is unfolded in adaptation to local conditions Electricity, electric power, the fresh water that islands and reefs not only may be implemented are self-sufficient, moreover it is possible to which the ecology of effective protection islands and reefs fragility is conducive to improve Survival ability, the capability of sustainable development of islands and reefs.Wind energy development, assessment are leading.
Forefathers are made that very big contribution in terms of wind power features analysis, but so far, about grinding for wind energy grade zoning Study carefully extremely rare, and this work substantial connection is to the reasonability of marine wind electric field addressing.In October, 2005, U.S. Department of Energy (United States Department of Energy) country new energy laboratory (NREL) is provided using QuilSCAT wind fields Material, depicts the wind energy grade zoning map in global marine site.2014, Zheng Chongwei and Pan Jing utilized CCMP Wind Datas, depict The wind energy grade zoning map in global marine site.Grade zoning can provide certain ginseng for macroscopical addressing of wind energy development twice for this It examines, but on the whole, the Territorial Difference of grade Zoning is not notable, as southern hemisphere and northern hemisphere westerlies belongs to 7 grades substantially Wind energy cannot provide reference for the wind-power electricity generation addressing in westerlies well.In addition, traditional wind energy grade regional project is only It is solely to consider the size of wind energy concentration, or consider the frequency that wind speed size, the size of wind energy concentration, effective wind speed occur Three wind energy elements, do not account for marine environment feature substantially, are easily separated from the actual demand of ocean engineering.
From above problem analysis, although inventor recognizes wind energy grade criteria for division at present, element is assessed It is unilateral, it is easily separated from the actual demand of wind energy development.Many difficult points such as data volume is huge, technology content is high cause there is presently no Wind power features and the wind energy resources grade criteria for division of marine environment feature can be considered, this just can not be offshore wind farm, Feasibility study, businessization operation of sea water desalination etc. provide science and technology support, aid decision.
Invention content
Goal of the invention:
With Delphi methods (expert consulting flexible strategy method), construct a set of can consider resource characteristic and environmental characteristic comprehensively Wind energy resources grade zoning new standard, for the both macro and micro addressing of offshore wind farm, islands and reefs wind-power electricity generation etc. provide science according to According to, aid decision.
Invention system title:Wind energy resources grade zoning (i.e. addressing) new technology
It invention system English name and writes a Chinese character in simplified form:New Wind Energy Classification Scheme
Referred to as:NWECS
The soluble problems of NWECS, the advantageous effect of the present invention:
(1) present invention in addition to the wind energy resources feature of tradition concern, while also examining during realizing wind energy grade zoning Considered it is a series of with the closely related element of ocean engineering, Zoning closer to wind collecting, offshore construction, prevent and reduce natural disasters Actual demand.
(2) traditional wind energy grade regional project only solely considers the size of wind energy concentration, or considers that wind speed is big Three wind energy elements of frequency that small, wind energy concentration size, effective wind speed occur.Present invention additionally contemplates that the stabilization of wind energy Property, Maximum wind speed, energy level frequency, the depth of water, offshore distance, can more fully reflect feature, the use value of wind energy.
(3) Territorial Difference of the invention that wind energy grade can be embodied well, and traditional wind energy grade regional project Then it cannot achieve.In traditional scheme, entire southern hemisphere and northern hemisphere westerlies belongs to fresh gale energy substantially, this cannot be well Wind-power electricity generation Site Selection in westerlies provides reference.
(4) present invention can be not only used for macroscopical addressing of a wide range of marine site wind energy development, can be also used near islands and reefs The microcosmic structure of marine site wind energy development.
(5) present invention expands tradeoff to the significance level (weights of i.e. different elements) of different elements, and this is in tradition Wind energy grade regional project do not account for.
(6) present invention can suitably adjust the weight of different elements according to actual demand.Such as:The wind energy of A islands and reefs The depth of water and offshore distance are especially concerned about in exploitation, then it, can suitably upper water transfer during the zonings such as the wind energy of A islands and reefs surrounding waters Deep and offshore is apart from shared weight;B islands and reefs are high to the stability requirement of wind energy, then in areas such as the wind energies of B islands and reefs surrounding waters During drawing, the weight shared by stability (coefficient of variation, monthly variation index, index of seasonal variation) can be suitably raised.
(7) currently, seawave power generation has obtained international extensive attention, but never wave energy grade criteria for division, The present invention can be equally transplanted in wave energy grade zoning.
Description of the drawings:
Fig. 1 is the work flow diagram of offshore wind energy resource grade zoning new technology.
Specific implementation mode:
The present invention is the new technology of offshore wind energy resource grade zoning, and step includes:
The wind energy concentration number of long-term sequence is calculated using the computational methods of Wind Data, wind energy concentration in the first step According to;
