Specific embodiment
Following embodiments are proposed merely for the purpose of illustration, and these embodiments do not limit protection scope of the present invention.
If all Wind turbines of wind power plant all run in the way of maximal wind-energy capture, upwind unit can be caused to capture wind Can be excessive, wind speed successively decreases with the wake flow direction of propagation, and the wind speed loss of lower wind direction unit input is larger, it is difficult to realize output of wind electric field Efficiency is maximized.Therefore, it is necessary to coordinate the wind energy of each unit capture, so that wake flow distribution in regulating wind power, improves unit Between pneumatic coupling, optimize wind power plant active power output efficiency.
Fig. 1 shows the flow chart of the Large Scale Offshore Wind Farm site selecting method based on wake effect proposed by the present invention.
The method according to the invention, wherein Large Scale Offshore Wind Farm include multiple wind power plant units, the site selecting method bag Include following steps:
Step one:The setting of single wind power plant unit, collection draft the single-machine capacity of wind power generating set, power curve and The technical parameters such as thrust coefficient, and wind power plant meteorological data.Based on these data, the blower fan of single wind power plant unit is determined Arrangement and capacity.
Step 2:Site selection model is set up for single wind power plant unit.The model set up is:
In formula:CwakeIt is wake effect, CTIt is thrust coefficient, D0It is preceding exhaust fan impeller diameter, k is attenuation constant, X01For The distance of two Fans impellers, AoverlapIt is A overlay regions,It is rear exhaust blower wind sweeping area;
Wherein attenuation constant K is 0.04.
Step 3:Multiple wind power plant units combine to form the Large Scale Offshore Wind Farm.
In general, marine wind electric field unit addressing, it is upward in crosswind by taking larger spacing on prevailling wind down wind Smaller spacing is taken, and reduces the output loss that wake flow is caused.Preferably, according to the present invention, the combination of multiple wind power plant units, bag Include and multiple wind power plant units are arranged with optimization and capacity judgement, control formed wind power plant unit itself and the wind Within setting range, wherein Rule of judgment is maximum wake effect C to wake flow in electric field between unitwakeFor:12%<Cwake< 16%.
Step 4:Based on the site selection model, after judging that the multiple wind power plant unit is combined, each wind power plant unit Between and single wind power plant unit itself wake flow reasonability, with this check single wind power plant unit capacity set and select Location correctness, is modified;The reasonability for judging wake flow be by control to be laid out between blower fan arrangement mode, wind power plant unit with And the environmental factor such as protection zone, navigation channel, culture zone, and then check site selection model boundary condition;As final result falls into setting model Within enclosing, then terminate judging.The reasonability for judging wake flow be by control to be laid out between blower fan arrangement mode, wind power plant unit with And the environmental factor such as protection zone, navigation channel, culture zone, and then check site selection model boundary condition;As final result falls into setting model Within enclosing, then terminate judging.
Step 5:Determine Large Scale Offshore Wind Farm addressing.
If final result does not fall within setting range, single wind power plant unit site scope is adjusted, repeat checking calculation, directly Fallen within setting range to final result;Minimum spacing L≤3km between wherein adjacent wind power plant unit.
