Heliostat 12 is safeguarded on the surface of mirror 13.Safeguard that vehicle 30 by the permanent driver's compartment 42 of radial directed and vertically forever can be driven
Sail district 40 close to solar energy field 16.Therefore the various sections of heliostat 12 are separated from each other and allow to safeguard by driver's compartment 40 and 42
Vehicle 30 is close to heliostat.Safeguard that the operation of vehicle can depend on the animal or such as of the such as Testudinis 72 in specific driver's compartment 40
The position on the animal habitat ground in cave 74.Along with safeguarding that vehicle 30 advances along driver's compartment 40, if it runs into habitat 74, then
It turns back along its road and attempts walking around habitat 74.Such as, safeguard vehicle 30 can from top close to habitat, thus
Can close to its by from bottom close to and the heliostat that can not arrive.If safeguarding that vehicle 30 is when advancing along driver's compartment 40
Run into the animal 72 of movement, then can reduce cleaning speed and drive safeguarding to leave before vehicle 30 arrives this position providing animal
Sail the sufficient time in district 30.
Alternately or additionally, safeguard that vehicle 30 can wait before advancing along the passage of design in driver's compartment 40 straight
Driver's compartment is left to animal.Can wait in view of being blocked by animal based on estimating that the time in driver's compartment is determined by animal
Or pursue and replace passage.(such as, can estimate that Testudinis will spend in driver's compartment than the animal faster moved according to species identification
More time), in 1 year the time and/or for particular animals solar energy field in historical record speed carry out this estimate.
In the case of estimating that time quantum is less than predetermined threshold, then safeguard that vehicle can suspend along passage until animal is not logical in stop
Road.Otherwise, safeguard that vehicle can advance to avoid blocking along replacing passage.
In another example, control system 60 can be controlled so that the time period of prolongation will be reached in the channel in response to animal

Specify habitat position.
Alternately or additionally, can be with the every day of analyzing animal 72 or annual Move Mode to predict the position/shifting of animal 72
Move or determine the position of habitat 74.For example, it is possible to monitor the movement of animal (or a treated animal) within a predetermined period of time, such as
Several days, one week, one month or even some months.Based on these data, can be as the letter of time in time or a year in a day
Number predicts where animal or fauna are normally at.Therefore can forbid safeguarding that vehicle enters predicted position in those time.
Such as, Testudinis may the most earlier the time (or the special time in a year) spend more time in the first region, and
And when closer to night (or another time in 1 year) spend more time in the second area.Therefore dimension can be forbidden
Protect the vehicle relatively early time in one day or carry out in the second area operating in the first region when closer to night or
It is at least allowed to operate in the case of having some constraint.
In an embodiment, can exist in the field 16 of heliostat 12 can be close for having ready conditions of certain maintenance vehicle 30
Passage or driver's compartment 90 of having ready conditions.Driver's compartment 90 of having ready conditions refers at the illuminator 13 of heliostat 12 being adjacent to driver's compartment
The only come-at-able special modality by solar energy field 16 of certain maintenance vehicle 30 when specific orientation.Such as, reference Fig. 9,
Condition driver's compartment 90 is there are between a pair heliostat 12 of solar energy field 16.When the illuminator of heliostat 12 is in basic horizontal
Orientation 13HTime, safeguard the width W of vehicleBMore than the width between the end of illuminator, thus prevent from safeguarding that vehicle is along passage
90 pass through.When the illuminator of heliostat 12 is in substantially vertical orientation 13vTime, safeguard the width W of vehicleBProp up less than heliostat
Distance W between support structure 15HC, thus allow to safeguard that vehicle passes through along passage 90.
Heliostat used herein can include single illuminator (see for example 36) or can rotate series connection with rigid body
The mirror assembly of one or more illuminators (seeing Figure 37) that ground rotates.The mirror assembly 13 of specific heliostat 12 is permissible
Have by coordinate pair such as in order in preset timeThe orientation limited, wherein, θiRepresent the elevation angle andRepresent azimuth.Heliostat 12 can have one or two rotary freedom, and can describe according to the elevation angle/azimuth
Or represent this rotation in any other manner.
In order to safeguard that vehicle 30 passes through along passage 90 of having ready conditions, it is not necessary to illuminator to be arranged in the position of perpendicular
Put 13v.On the contrary, can by heliostat 12 and safeguard vehicle 30 be designed and arranged to allow illuminator 13 be in be different from vertical
Angle.For example, it is possible to the width W at the top of vehicle 30 will be safeguardedTWith the width W safeguarded at the bottom of vehicle 30BIt is designed to i.e.
Make as shown in Figure 9 when illuminator 13 and vertical 13vWhen differently positioning, allow also to safeguard that vehicle 30 passes through along passage 90.
On the contrary, the heliostat 12 in other parts of field 16 can be the most closely spaced so that even if working as illuminator
13 are arranged in substantially perpendicular orientation 13vTime, distance W between adjacent heliostat supporting construction 15HBAgain smaller than maintenance cart
Width WB.Therefore, can be with the distance of Shortcomings to allow to safeguard that vehicle 30 is by regardless of whether reflective between heliostat
Mirror orientation how.Certain maintenance vehicle between adjacent heliostat close to depending on safeguarding the size of vehicle 30, heliostat 12
Size, the structure of heliostat 12, the layout of heliostat 12 and/or heliostat 12 between the combination of separating distance.Can be by
This type of heliostat is referred to as concealed heliostat, because it safeguards that vehicle 30 is the most close.
Figure 10-Figure 11 relates to wherein safeguarding that vehicle 30 can not also pass through in the region taken by heliostat 12
Condition.In Figure 10-Figure 11, the center of each heliostat (or barycenter or supporting construction) is depicted as round dot, heliostat anti-
Light microscopic 13 is represented as rectangle, and it can rotate around this round dot, and the range of movement of the illuminator 13 in plane graph is by table
The circle being shown as around round dot.Figure 10-Figure 11 has been simplified and has assumed that the region of each heliostat is continuous print and is shaped as circle.
This rough schematic view should be interpreted as restrictive.Additionally, Figure 10-Figure 11 relates to from 3d space to the projection in 2D space, i.e.
Plane or birds-eye view.It will be appreciated that the stop feature of any heliostat can be relevant with the 3D heliostat with any shape
Any mode is applied.Therefore the mirror assembly of heliostat can have any shape, and heliostat itself can have and appoints
What configuration.
As shown in the left side of Figure 10, vehicle 30 can be along passage 90 of having ready conditions through solar energy field, because being adjacent to lead to
The illuminator 13 of the heliostat 12 in road 90 is in the distance bigger than the width of vehicle 30 due to the orientation of illuminator 13.So
And, when illuminator 13 is differently oriented about the group 100 of heliostat 12, passage is blocked and stops vehicle 30 to pass through group
100, as shown in the right side of Figure 10.It is noted that while the illuminator 13 in as directed group 100 implys that vertical orientated,
But this diagram also may indicate that in substantial horizontal orientation or hinders the illuminator 13 in any other orientation of passage.
With reference now to Figure 11, the layout of the heliostat 12 combined with the size safeguarding vehicle 30A is so that unconditional
Ground resistance keeps off a car a 30A through the section 110 of heliostat 12.Even if vehicle 30A can in bottom row by a pair heliostat (i.e.,
There is enough width gaps), due to the obstruction caused by the heliostat in the second row, it is possible to stop vehicle to further pass through
?.Especially, the length and width of the vehicle 30A combined with the layout between heliostat and spacing prevent vehicle 30A along
Passage is turned to avoid and the collision of the heliostat in the second row.
On the contrary, safeguard that vehicle 30B is shorter than in length and safeguard vehicle 30A, but there is identical width.Although preventing from safeguarding
Vehicle 30A by section 110 through the field of heliostat 12, but safeguard size that vehicle 30B reduces due to it and can be along having
Condition passage 114 moves.It should also be noted that the heliostat 12 of the passage 114 that can control to be adjacent to have ready conditions and make it again fixed
To with along with safeguarding that vehicle 30B is along before passage 114 and then adapt to it and turn and mobile.
Finally, safeguard that vehicle 30C is shorter than in length and safeguard vehicle 30A or 30B, but have identical Breadth Maximum and
Circular front shape.Although safeguarding that vehicle 30B forces, such as it, the heliostat needing to be adjacent to its passage 114 through field
Redirect, but safeguard that vehicle 30C is sufficiently small so that it can be maintained at unanimously at the illuminator 13 of heliostat 12
Turn in the case of on position and move along passage 116.Therefore, the concept of concealed heliostat and/or concealed position is (right
Than have ready conditions can close to heliostat or have ready conditions can approximated position) be the layout based on vehicle and heliostat, particularly vehicle
Size or radius of turn.
In an embodiment, the island of the concealed heliostat in solar energy field 16 can be with permanent driver's compartment and/or have ready conditions

's.Such as, passage 90 of having ready conditions can be along radial directed or the line of tangential orientation, along by the crenellation pattern of field,
Along any other pattern or combinations of patterns or advance even along random.Although all illuminators 13 quilt along passage 90
It is shown in the position of perpendicular to allow to safeguard that vehicle 30 passes through, but it is also contemplated that illuminator 13 is according to " instant
(just-in-time) " agreement operates, and is the most only directed in order to allow dimension when safeguarding vehicle close to illuminator 13
Protect the position that vehicle 30 passes through.Therefore, the major part of passage 90 may be intercepted by illuminator 13, and it continues the reception in collimation tower
Machine, until needing to redirect to allow to safeguard that vehicle 30 passes through.
This same " immediately " concept can also be applied to illuminator 13 to be safeguarded, such as when replacing mirror assembly
Time.In other words, concealed heliostat 12 makes insolation focus on receiver by continuing, until approaching the clear of specific heliostat 12
Clean.The obstruct of the heliostat sight line during maintenance activity can be taken into account by the additional control of heliostat.Such as, one is safeguarded
Or multiple heliostat (such as using arm 36B) can stop from not requiring to safeguard or through safeguard one or many
The reflection insolation of individual heliostat so that it is the appointment aiming point on the target in tower 18 can not be arrived.Therefore, it can make provisionally the settled date
Mirror aims to avoid the stop caused by arm 36B/cover again.
It should also be noted that the position of passage 90 needs not be one group of passage or rule passage (the most as shown in figure 12 concentric
Circular channel).On the contrary, passage 90 can be special channel and/or irregular passage.Safeguard that vehicle 30 can be with heliostat
Suitably control to select it close with allow between it by route of solar energy field 16.Therefore, at any time, may go out
Existing is safeguard vehicle 30 itself be hidden in solar energy field 16 internal and do not have any specific leaving channel be it will be evident that but
Be heliostat 12 suitably control passage can be allowed to open along with safeguarding vehicle 30 to move.This type of special channel can also be used
Avoid the animal in solar energy field and/or its habitat.For example, it is possible to it is special by optionally select by heliostat
Passage and control to safeguard that vehicle is motor-driven around animal and/or animal habitat ground.The settled date along this special channel can be controlled
Mirror is to allow to safeguard that vehicle passes through.
Heliostat 12 away from passage 90 is not that vehicle 30 can be immediately adjacent to;Alternatively, middle heliostat stops directly
Close.In order to arrive these hiding heliostats 12, it is attached to safeguard that one or more arm 36B of vehicle 30 can cross centre
Heliostat 12.Arm 36B can include that one or more cleaning end 36C is simultaneously to clean multiple heliostat.Cleaning end 36C
Can include brush or short range ejector filler or spraying apparatus, it can be grasped in distance less than 2m between equipment and minute surface
Make.Safeguard that vehicle 30 passage 90 of can circumferentially having ready conditions continues, its tail stays the cleanest heliostat

Table 2 below shows the heliostat density value of the diverse location for identifying in fig. 24.The density listed in table 2
Value illustrates and the heliostat density design in the different quadrants of field or part can be become change, even if position with tower is otherwise
Equidistant.It addition, the heliostat density ratio of the position for similarly positioning relative to tower can be such as the distance with tower
Function and change.Such as, north and south heliostat density ratio can increase along with the distance with tower.
In order to illustrate, position L13And L1It is shown in the southern field 220S at same distance and north section 220N
Density is different.Can be for the position similarly positioned relative to tower 18 in south section 220S and north section 220N
Define north and south density ratio.Especially, for L13And L1For;North and south density ratio is 2.32/2.09=1.11.By L14Value and L2
Value compares and obtains the north and south density ratio of 2/1.66=1.2.By L15Value and L3Value compares and obtains the south of 1.62/1.25=1.3
North density ratio.Therefore, by increasing the distance with tower 18, between the same position (i.e. in the distance that tower 18 is equal) arranged
North and south density ratio can increase.
Table 2: the density of the heliostat of the various location in solar energy field
Heliostat density in the southern part of solar energy field can exceed the heliostat in the northern part of solar energy field
Density.Embodiment described in Figure 22-Figure 24 and Biao 2 can be applicable to solar energy field on the Northern Hemisphere.In the Southern Hemisphere, this knot
Fruit will be contrary.In other words, in the Southern Hemisphere, the heliostat density in the northern part of solar energy field will exceed solar energy field
Southern part in heliostat density.
In on the Northern Hemisphere, south heliostat is likely to be due to cosine effect and trends towards being weaker than its north correspondence positioned equally
Thing.On the contrary, in the Southern Hemisphere, north heliostat is likely to be due to cosine effect and trends towards being weaker than its south correspondence positioned equally
Thing.Then in the region with more weak heliostat, (region relative to having stronger heliostat) is disposed with the density increased
Heliostat is to provide additional insolation reflectance to be probably favourable to compensate or to compensate this weakness at least in part.Work as reception
When facility have north and the south of substantially the same size, the south part of solar energy field is (i.e. in the most efficient district
Territory) in the heliostat density of increase the heat flux evenly realizing on the surface of receiver or uniform temperature can be helped to divide
Cloth.Additionally or alternatively, more weak heliostat can include bigger illuminator.
Furthermore it is also possible to definition thing density ratio.In order to illustrate, position L7And L19It is shown in the west at same distance
Density in side section 220W and east section 220E is different.Can be at west section 220W and east section 220E
In the position that similarly positions relative to tower 18 to define thing density ratio.Especially, for L7And L19For, north and south density ratio
It is 2.14/2.08=1.03.By L8Value and L20Value compares and obtains the north and south density ratio of 1.88/1.75=1.05.By L9Value with
L21Value compares and obtains the north and south density ratio of 1.52/1.4=1.08.Therefore, by increasing the distance with tower 18, same layout
Thing density ratio between position (i.e. in the distance that tower 18 is equal) can increase.
Heliostat density in the western part 220W of solar energy field can exceed in east part 220E of solar energy field
Heliostat density.The electricity charge of the electricity in afternoon hours can be more than the electricity charge of the electricity in morning sessions.Therefore, may be used
So that the placement optimization of heliostat the most described herein is so that power generation in afternoon and/or maximum to the afternoon insolation of tower 18
Changing to realize insolation or the flux of aspiration level on the most several hours periods receiver in tower 18, this may be used for
Income or income/field cost function is made to maximize or at least increase.This type of income/field cost function can be by the density of heliostat
Or the total size of number and/or illuminator or illuminator density takes into account, such as with catch each heliostat income or
Illuminator capital cost certain than or other functions.For example, it is possible to make the placement optimization of heliostat with the most several little
Substantially uniform insolation is obtained on all flux receiving surfaces of receiver around time during.In another example, permissible
Make the placement optimization of heliostat so that being incident on, in the face of the most several hours periods, there is the solar energy of poor efficiency heliostat
Insolation amount or flux on the receiver surface of field areas maximize or at least increase.Afternoon power generation maximization and/or
To tower insolation in afternoon maximization and/or in the afternoon period realize on the receiver uniform insolation/flux can with morning electricity
Power produce and/or to tower insolation in morning and/or in the morning during to realize uniform insolation/flux on the receiver be cost, because of
The total amount of sum and/or illuminator area for being deployed in the heliostat in solar energy field is probably fixing and/or is subject to
Constraint.
When design has excellent for power in afternoon of a limited number of heliostat (such as due to budget or geographic constraint)
During the solar energy field first produced, western part that can be on the scene is arranged more greater number of heliostat than east part.Even if field
West section in heliostat location same with east section on the scene heliostat compared with receive the amount side of insolation at tower
Face may the most weak (i.e. the most efficient), for produce improve the standard afternoon electric power purpose, should
Heliostat is arranged can also preferred these more weak west heliostats.
In order to design solar energy field, can set up cost function, its constraint can be included at least two basic orientation
The sum of the heliostat disposed in the solar energy field of the part in (such as north and south, thing) and/or total illuminator area.May require that
Solar energy field has the power generation and/or anti-to the total insolation of raising of the target being associated with solar column in afternoon of raising
Penetrate, even if altering course as cost with power generation in morning and/or from the morning insolation of heliostat to solar column target.In response to this one-tenth
This function, can design and specify the heliostat layout disposed, and wherein, in a part on the scene, ratio is along contrary basic orientation
Field a part in there is more heliostat (or the average reflector size or bigger of bigger heliostat density or bigger
Add up to reflector size), such as, the northern part of the same orientation of greater number of heliostat contrast in the southern part of field.
Alternately or additionally, it is possible to use this cost function designs solar energy field, wherein, than district in the Orient in west section on the scene
Dispose more heliostat in Duan and/or dispose with bigger density than in section in the Orient in the section of west.This deployment is permissible
According to any scheme and/or feature, include but not limited to any combination of scheme disclosed herein and/or feature.

In an embodiment, multiple single column solar energy field of common location can be provided in single geographical location, such as Figure 33
Shown in.For example, it is possible to provide four tower 18A-18D with respective solar energy field 330A-330D.In an embodiment, permissible
Each 330A-330D is only made to be associated with its tower 18A-18D.Can be only configured to make insolation change by the heliostat in each field
To its respective tower, the heliostat in 330A will be configured to only make insolation be redirected to tower 18A on the spot.In field 330C, 330C
The most southern region 332,334 can define by line 336 in the south of all tower 18A-18D.Various principle described herein can
To be applied to any 330A-330D or the combination of field.It is common that Figure 34-Figure 35 illustrates for tower and solar energy heliostat field
Other configurations of location.In the example of Figure 35, it is believed that some part 352,354 is for specific a line solar energy field
Southernmost for 350C, 350D, 350F.In an embodiment, from the region of any heliostat or heliostat to its respective tower
Ratio distance and another the distance from any heliostat or heliostat field to tower can less than 0.9,0.7,
0.5,0.3,0.2,0.1 or 0.05.
In an embodiment, can be configured to the heliostat in one or more in field alternatively guide at different tower
Insolation is to compensate less efficient heliostat.Such as, the tower 18A in Figure 33 " can use " south of field 330C from tower 18C
Some heliostat (the most more efficient heliostat) in part is to compensate the heliostat in the southern part of field 330A (the most less
Efficient heliostat).Therefore the heliostat used from the north part of field 330C (i.e. can be existed from for tower 18C
The north of tower 18C) it is converted into for tower 18A (i.e. in the south of tower 18A) several in the most efficient orientation
It is orientated the most efficiently on He, but, the heliostat number of the increase in the south now pointing to tower 18A compensates for field
The efficiency of the reduction of the south part of 330A, and may be used for promoting the homogeneity condition of receiver, at least when in tower 18A
When receiver has north and the south of substantially the same size.
The point schematic diagram of solar energy field is the figure in proportion describing the heliostat layout in solar energy field, thus, with single
Round dot represents single heliostat, is each respectively positioned at each heliostat position (see for example Figure 41-49).Although some point
Schematic diagram usually includes virtual link line or arc (it is described in above it arc or line deploying heliostat), but there is not this
The requirement of sample.In the some schematic diagram of some prior art solar energy field, major part in the non local region of solar energy field or
All heliostats are typically arranged according to orderly arc layout patterns (see for example Figure 38-Figure 39).Show in other prior aries
In example, the layout of heliostat can be retrained so that with rule on the straight line through the sizable non local part of solar energy field
Heliostat is disposed at interval then.In both cases, the heliostat in prior art systems is disposed on line with aturegularaintervals
Or on arc/curve.
Figure 38-Figure 39 relates to the highly constrained and/or layout patterns of high-sequential, is particularly restrained to through solar energy
The layout of the heliostat of the deployment on the line of field or arc.On the contrary, the embodiment of solar energy field disclosed herein includes wherein not
(i.e. not used for the separate overall situation geometry on the border specifying region and/or field in the case of being constrained in any certain line or arc
Constraint) make heliostat dispose the region of optimized solar energy field.Therefore when the point seeing open solar energy field with bigger ratio
During schematic diagram (contrary with the little localized areas in the sizable region only considering heliostat layout), big in solar energy field
Non local may not there is recognizable notable line chart case or notable arc pattern apart from interior.
In an embodiment, can be to promote to be mapped to day useful energy form more efficient of such as steam, electricity or Biomass
The mode of rate conversion arranges heliostat.Can be by so that be constrained in the feelings of certain line or arc in the deployment not making heliostat
Arrange under condition that the mode of these farther heliostats is disposed and be relatively farther from some of tower, most of or essentially all heliostat
And make the efficiency optimization of solar column system.By loosening this type of constraint and by using one or more optimization routine
(i.e., wherein this routine can enjoy more degree of freedom in sizable region of solar energy field, but is not necessarily whole
), can be compared to the efficiency realizing improvement for more orderly placement scheme.
The efficiency of solar energy field can relate to the insolation of the receiver pointed in tower of the function as capital investment cost
Overall strength or amount.For example, it is possible to survey divided by certain tolerance of the gross area of the illuminator of heliostat as total reflectance
Amount efficiency.It addition, the solar energy field obtained from optimization be likely to be due to the predefined passage by heliostat field shortage and more
Add and be difficult to keep.The use of the driver's compartment of having ready conditions in the region of solar energy field can at the line in not having these regions or arc about
Restraint, allow to safeguard vehicle allows field layout optimization in the case of accessing the heliostat in these regions simultaneously.
Heliostat in the one or more regions not making solar energy field is disposed in the case of being constrained in certain line or arc,
It is one or more that the layout obtained from extensive optimization routine can show following characteristics:
(1) when watching some schematic diagram (or quite a few of field) of field, the settled date in the perimeter of solar energy field
Mirror is not necessarily deployed in global lines layout and/or overall situation arc layout (or combinations thereof).Such as, the perimeter of the field of heliostat
Can be at least 2 times of the height for tower, 2.5 times, 3 times, 3.5 times or the distance of 4 times.
(2) even if total layout patterns of perimeter is not constrained in global lines or arc pattern, the most there is not heliostat necessary
Avoid the requirement that local pattern is disposed.Alternatively, the localization pattern of some can be observed.For example, it is possible to there is the settled date
Certain localization of mirror interrupts crenellation pattern, wherein, there is the many being interrupted each other and dispose throughout whole field fixed
Solar eyepiece zigzag cluster.
In an embodiment, the method for calculating heliostat layout can include global optimization, meta-heuristic and/or its
His computing technique.This type of calculating of heliostat layout can take wherein heliostat layout to there is no the non local district with field
The mode of the constraint (being i.e. not limited to the deployment on line or arc) that the orderly or arc on territory/line domination pattern is associated.Can use
Relatively high heliostat field insolation changed course efficiency parameters carrys out the heliostat layout that characterization result obtains.Optimization can be based on making
In one or more one day the time and/or in one or more 1 year the time by one or more parts of solar energy field
Maximization is sheltered on covered ground or ground that the target from solar column (or top) that heliostat realizes is seen.
Figure 38-Figure 39 represents first (" field 1 ") layout 380,390 in order, and wherein, heliostat 12 is deployed in central tower
On the RADIAL 384 initiated on concentric circular 382 around and/or at tower.Figure 40-Figure 41 represent be not constrained in certain line or
Second (" field 2 ") in heliostat layout in each several part of the field being optimised in the case of arc.Relative to Figure 38-figure
Both second (fields 2) in first (field 1) of 39 and Figure 40-Figure 41, only illustrate wired number for the sake of understanding
Heliostat;But, the practical embodiments of solar energy field can include being deployed in e.g., from about 4km2Area in more than 50000
Heliostat.This heliostat can be of similar shape, size and height.Two fields all with lead to tower 18 four radial directions just
Road 42 is characterized, such as, as shown in figure 42.
Figure 42-Figure 49 illustrate appear on the scene 1 arc constrained layout (i.e. Figure 42, Figure 44, Figure 46 and Figure 48) and field 2 optimization without
Contrast between constrained layout (i.e. Figure 43, Figure 45, Figure 47 and Figure 49).Especially, Figure 43 represents northeast part 400NE of field,
Figure 45 represents that the Counties of North-west Five 400NW, Figure 47 of field represent southeast part 400SE of field, and Figure 49 represents the southwestern part of field
400SW。
In on the scene 2, at the heliostat (such as in middle section 402) close to tower 10 and the heliostat away from tower 17
The difference in terms of layout is there is between (such as in perimeter 400).Can be fixed by remote heliostat (in perimeter 400)
Justice is to have the ratio of the tower of at least 2,2.5,3,3.5,4,4.5,5,7.5 or 10-between heliostat distance and the height of tower
Heliostat.In middle section 402, can with more in order, the most intensive layout arrange heliostat (be such as constrained in line or
Arc), simultaneously can be not optimum to the deployment of the heliostat made in the case of any constraint of line or arc in perimeter 400
Change.
Multizone scheme can be disposed, wherein, for the region close to tower 18, such as region 402, advise with certain
Then lattice disposes heliostat.This regular grid pattern or other kinds of loading (packing) pattern can improve fixed
Solar eyepiece loads and/or makes it maximize, even to use too much heliostat or too much to add up to illuminator area to make every illuminator
Area tolerance maximizes as cost.In these closed areas, significant heliostat layout patterns can be the net of very well ordered
Grid pattern, such as triangular grid pattern or hexagon close loading pattern.For the region further from tower 18, such as region
400, wherein heliostat is away from tower 18, in the case of not considering specific pattern or desired placement scheme, disposes optimum
Change.In an embodiment, can be at the top of tower or its neighbouring position (or position on any other ground) ground of seeing
Face coverage and by not requiring that the heliostat on line or rule arc/curve is disposed (or by requiring the settled date on line or arc
Mirror layout but and further constrained layout thus it requires the layout of most of heliostats being in aturegularaintervals on line or arc) come
Make heliostat layout optimization.This type of optimizes and can cause for giving the relatively high of heliostat density and/or illuminator density
The ground that the illuminator of level causes is covered.This by the heliostat realization of the one or more positions in solar energy field is relative
High-caliber covered ground can be used for promoting that solar radiation is useful to the more efficient conversion of useful energy.
The concept of covered ground (or ground cover) is discussed below with reference to Figure 50-Figure 52.Cover whenever mentioning ground at this
During lid (or ground is covered or ground is sheltered or ground stops), it is about the height in solar column, such as being somebody's turn to do at tower
Solar energy field is seen at top or its neighbouring position.When certain region guarded the threshing floor from specific viewing location 500, such as from too
Sun can tower 18 top at or its neighbouring receiver 20 (or other targets), some part on ground will be from viewing location 500
Visible, and the illuminator 13 being intended to be directed to insolation the heliostat 12 at receiver 20 is hidden by other parts on ground
Cover.Viewing location 500 can correspond to the heliostat 12 position while following the sun on the target 20 of its reflection insolation (i.e.
Aiming point on target or receiver 20).When the region that limits of solar energy field has the heliostat of greater number and/or has ratio too
Sun can the heliostat of the big illuminator area in other regions of field time, this may cause wherein this restriction region to have higher degree
The situation of covered ground.
In addition to heliostat density and/or illuminator density, for wherein deploying the specific of the solar energy field of heliostat
The covered ground in region can depend on many additive factorss, includes but not limited to: time in (1) one day in time and/or 1 year
Between;(2) geographical position of solar energy field;(3) the actual heliostat cloth of the part of the solar energy field of its covered ground is being analyzed
Office (geometry of such as heliostat, the distance between such as heliostat, the angle connecting the vector of heliostat or heliostat layout
Any other aspect);(4) size of each heliostat, shape or height;(5) tower height (or its height and position permissible
It is the height that may not be the viewing location that the position with solar energy target such as receiver 20 overlaps);And (6) are from solar energy
Tower is to the distance of this part (the most determining or analyzing the part of its covered ground) of solar energy field.
In an embodiment, can be for the time in time and/or 1 year in one or more one day in solar energy field
Covered ground is analyzed in one or more positions.For example, it is possible to analyze one or more heliostat layout and according to by heliostat
The covered ground that layout provides distributes mark.Viewing location can be at solar column or the position of its neighbouring solar energy target
Put.Can distribute point according to the time in selected one day or in 1 year or according to certain time average or time-weighted average
Number.Alternately or additionally, mark can be calculated by analyzing the covered ground on the multiple positions in solar energy field.For inciting somebody to action
The heliostat of the given number being deployed in the given area on land and/or the heliostat illuminator of intended size, can exist
Many potential heliostat layouts.When heliostat is not limited to the deployment on line or rule arc/curve, potential heliostat layout
Number in fact can be sizable.Each in these potential heliostat layouts can be from different covered ground marks
It is associated.
Embodiment described herein can relate to produce describe in central tower solar thermal power plants at least some of fixed
The technology of the solar energy field layout of the position of solar eyepiece.Can perform heliostat configuration space search with analyze covered ground or
Other parameters derived from covered ground.Search volume corresponding to the space of possible heliostat placement scheme can be the biggest
's.As attempt use brute-force technology replacement, Global Optimization Algorithm For Analysis can make at least 50 in the heliostat in field, 100,
500, the position optimization of 1000 or 5000.It is, for example possible to use Global Optimization Algorithm For Analysis determines for solar energy field
The deployed position (that is, there is the heliostat of at least twice more than tower height degree to tower distance) of the heliostat in perimeter and not
This deployment is made to be constrained in certain line or arc.
The given covered ground that optimization instrument can be used to obtain in the big search volume of heliostat layout is led
Go out function or the approximation of overall optimum of the given part for heliostat field.Optimization instrument can include but not limited to
Global or local search is random/probability instrument, meta-heuristic algorithm, simulated annealing, hill climbing algorithm, genetic algorithm, dynamically
Programming and/or ant group algorithm.Covered ground derives function can include that the total ground of the time average throughout field or the region of field is covered
Lid.This time average ground coverage function can be in other day the time and/or other in 1 year several days preferential for cost
Select some months in summer and/or the weighting function of the coverage of face larger in several hours of dusk.
In an embodiment, for determining that the method for solar energy field layout can include being initially selected for what heliostat was placed
One or more parts of solar energy field.Position can be determined, in the large area of such as solar energy field for one group of heliostat
Heliostat, this type of region composition at least the 50% of solar energy field, 70%, 80% or 90%.Use one or more optimization
Technology, can generate the field placement scheme of the selected portion for solar energy field.Subsequently, can be according to the placement scheme generated
Heliostat is arranged in solar energy field.
Placement scheme generate so that being realized by heliostat at the top of tower or in terms of its neighbouring position
Covered ground or ground are covered can be by least partially optimization.Covered ground/cover can be only in solar energy field
Heliostat in region makes insolation be redirected to the tolerance of total capacity at top (or near top) of solar column.Also may be used
To use other to measure.Additionally or alternatively, for the one or more non local region of solar energy field, tower such as it is relatively distant from
The region of solar energy field, when being used in the placement scheme optimization of one or more parts of solar energy field, can be not
Placement scheme is determined in the case of being constrained in any certain line or arc.
Figure 50-Figure 52 can relate to the west heliostat being positioned at the west of tower 10 and viewing location/impact point 500, although
The reasoning that is similar to can be obtained for the heliostat in other sections of solar energy field.With reference now to Figure 50, due to heliostat 12
Follow the sun with the impact point 500 insolation 14 being reflexed on receiver 20, the therefore orientation (example of the illuminator 13 of heliostat 12
Such as the elevation angle and/or azimuth) all change on whole daytime, from the orientation 13 in morningMOOrientation 13 to afternoonAF。
From viewing location 500, the existence of the illuminator 13 of heliostat 12 will cover ground.Due to time in different one day
Between the different orientation of heliostat, the size in shielded region and/or position can change for each heliostat.Such as, by
Orientation 13 in the illuminator in morningMO, produce shielded region 502 relative to viewing location 500, simultaneously the illuminator in afternoon
Orientation 13AFLess shielded region 504 can be caused.For the time in any a day in the Northern Hemisphere, by the positive north at tower
The independent heliostat of the given distance size in shielded region, ground that causes can be more than in the due south being deployed in tower
The size in shielded region, ground that will be caused by same independent heliostat in the case of at same distance.In the Southern Hemisphere, this
Situation will be contrary so that south heliostat can cause the more ground of each heliostat to hide compared with the heliostat of the corresponding north
Cover.
Figure 51 illustrates two heliostats 12 in the west being both deployed in tower 10.The part 512 of illuminator 13 is relative
Stopped by adjacent heliostat 12 in viewing location 500.In other words, anti-by by heliostat 12 of the insolation reflected by this part 512
Light microscopic 13 stops and can not arrive viewing location 500.This part 512 can be considered as wasting illuminator space, i.e. anti-at some
Available illuminator space insolation being directed at receiver it is unused for during light microscopic orientation.It addition, by each illuminator 13
Overlap can be there is between the region covered, thus produce single shielded region 510 on the ground.By heliostat is farther
Ground separates, as in figure 52, each illuminator the shielded ground region produced become independent and different region 520,
522, there is gap 524 in-between.This gap 524 represents on its ground currently arranged and do not covered by heliostat in orientation
Region.Owing to this gap will be visible from viewing location 500, so it can represent wasting space, i.e. at some illuminator
Land insolation being directed at receiver it is not used to during orientation.
Part 513 and/or the quilt of each illuminator 13 being blocked can be used in the optimization of heliostat field layout
Distance between size and/or the shielded region of shaded areas, such as 510, the size in such as gap 524.Fixed by not making
Solar eyepiece layout constraint is in certain line or arc and the covered ground being included every density range that above-mentioned covered ground considers by realization
Optimum procedure, it is possible to obtain efficient heliostat layout.
Retrain by avoiding solar energy field layout is applied arc or line, can make the amount on ground covered by heliostat (i.e.
A time point or within one or more time periods time average) optimization.In an embodiment, this can relate to wherein allowing
Heliostat position depart significantly from can in solar energy field restrictive rule or in order any line of pattern or the situation of arc.Additionally
Or alternatively, the deployment of heliostat can be made to be confined to such as concentric arc;But, the heliostat along each arc is placed can be
The most irregular.Additionally or alternatively, the deployment of heliostat can be constrained in centered by solar column
Concentric driver's compartment in region in.The calculation of such as simulated annealing can not have any further geometrical constraint (such as
Arrange on online or arc) in the case of determine the optimum position of heliostat in each region.This algorithm can be based on example
Cover such as the ground in terms of the target from solar column and make the heliostat position optimization in each region.
With reference now to Figure 53, it is shown that the part of the solar energy field at the top of tower 18 or in terms of its neighbouring position,
The view of the northern section of the interior section 402 of such as field 2 in Figure 40-Figure 41.Figure 54 shows a part for solar energy field,
The northern section of the exterior section 400N of such as field 2 in Figure 40-Figure 41.Similarly, Figure 55-Figure 56 illustrates Figure 40-Figure 41
In the interior section 402 of field 2 and the southern section of exterior section 400S.Therefore Figure 53-Figure 56 illustrates in solar energy field
Character is covered on the ground of the layout of heliostat.With as compared with time from the point of view of a schematic diagram (i.e. the birds-eye view of solar energy field), this is too
Sun can seem at the top of tower or when seeing near it more in order (that is, because it is designed to make ground cover field
Bigization).
Exterior section, the heliostat in the region 400 of all solar energy field as shown in figure 40 for field are placed and can not be examined
Consider specific bank or arc pattern, the heliostat of the interior section being simultaneously used for field place can highly constrained in specific line or
Arc.Such as, in Figure 58, closer to tower field 2 fields inside 582 can more in order and/or substantially conforming to grid layout,
The position of heliostat in external field 580 can be determined in the case of not being constrained in certain line or arc simultaneously.For Figure 57 institute
The field 1 shown, the fields inside 572 close to tower and the external field 570 away from tower both have according to line chart case (at interior section
In 572) or the heliostat disposed of arc pattern (in exterior section 570).Contrary with the field 2 of Figure 58, the settled date of the field 1 in Figure 57
The position of mirror is selected as being in aturegularaintervals along global lines or arc pattern (being i.e. constrained in the deployment on line or arc pattern), this
Covering less than optimal ground of time in time and/or one or more 1 year can be caused in one or more one day
Lid.Although the field 2 in Figure 58 has wherein it is observed that the perimeter 580 of local line or arc pattern, it is to be noted that
It is to determine in the case of the deployment of specific global lines or arc pattern not requiring for the position of these heliostats.Phase
Instead, in the layout of field 2, recognizable any local pattern is relative to the optimized of covered ground rather than for along certain
The product of the requirement that the heliostat of a little lines or arc is disposed.

It is useful to dispose heliostat that mirror is constrained in the heliostat scheme of line or arc.Figure 61 figure-65 shows ' ground blocking capability '
Particular case (i.e. only the covering of ground from the point of view of observer at the top of tower or at the top of tower or near it
Cover).Position at the top of tower or near it is from the point of view of observer, and heliostat illuminator ' covering ' is (equivalently,
" shelter " or " hiding ") ground of solar energy field.When heliostat mutual sufficiently close together time, the time in some is one day, adjacent
The sight line of heliostat overlapping (again from the point of view of the observer from tower) decreases relative to adding up to heliostat reflective mirror
Long-pending shielded floor area.It is fixed to make in the case of not by any constraint of the alignment forcing it online or on arc wherein
In the optimized embodiment of solar eyepiece layout, decrease the lap between adjacent heliostat, given identical density and heliostat
Size, compared with making heliostat constraint placement scheme online or on curve, it is achieved that ' ground is covered ' of bigger level.Explanation
The another way of this point is so that relative in tower when allowing heliostat to be positioned at not follow on the position of line or arc
It is bigger that efficiency (each heliostat or the dead area of per unit heliostat illuminator area) is covered on the ground of advantage point.

March, June, JIUYUE and ten of 3 times (i.e. 9AM, noon, 4PM) in a day of solar energy field position near Ivanpah
February result.In Figure 62 A, Figure 63 A, Figure 64 A and Figure 65 A, row B-H show represent see at the top of tower by heliostat
The ground shield parameter (G.O.) of the percentage ratio on the ground covered, and arrange I-N and show the heliostat of per unit floor area.Pin
The heliostat density being optimised performance trends towards closer to bigger in tower and southern part on the scene.It is different from ground to cover
Parameter, heliostat density does not changes, and the month being therefore not dependent in one day in time or 1 year.
Figure 62 B, Figure 63 B, Figure 64 B and Figure 65 B, row Q-V shows density normalization ground shield parameter, and it characterizes one day
In different time or the heliostat disposed according to heliostat placement scheme in month in 1 year cover the efficiency on ground
(GO.O/Dens).Row W-Y illustrates the G.O./Dens of 24 positions in two fields.Row Z-AB shows and arranges W-Y phase
With but used rough inaccuracy orientation to be averaging scheme and carry out being orientated the result being averaging.Row AC-ACK shows not by root
The ground shield parameter being normalized according to the heliostat illuminator density in given area (i.e. L1, L2...L24).
Figure 62 B, Figure 63 B, Figure 64 B and his Figure 65 B show that field 2 trends towards in terms of covering ground (i.e. from the top of tower
Place or see near it) more efficient than field 1.Especially, it can be observed that on some position, the heliostat in (i) field 2
Ratio between the G.O./density of the heliostat in G.O./density and (ii) field 1 tends to exceed 1 and i.e. exceedes at least percent
Several.
The example of Figure 61-Figure 65 show wherein heliostat be not constrained in the optimization of the heliostat layout of circular arc or line with
Wherein heliostat is used to be restrained to the comparing achieve bigger per unit than when heliostat layout is obtainable of line or arc
The ground coverage of illuminator area.Some embodiment relates to system based on central tower heliostat, and it includes being deployed in too
Multiple heliostats in sun energy field.Heliostat-Tower System can be deployed in example on any position in the Northern Hemisphere or the Southern Hemisphere
As more than 20 degree or more than 25 degree or more than 30 degree and/or less than 50 degree or less than 45 degree or less than 40 degree or less than 35 degree
At dimension.
On the scene 1 and 2 two, field in the case of, the layout of heliostat is remote from the characteristic of the field of tower.It is closer to the center sun
Energy tower, in the case of the notable deterioration in terms of not having system effectiveness, can dispose heliostat in the most constrained scheme.
Further away from center solar column, the optimal of heliostat can be realized by the layout in the case of not being constrained in line or curve
Arrange.Although for arrange heliostat prior art systems can with optimization, but its take constraint in the case of do so,
Such as make along the spacing between the heliostat of ranks (rank) optimized while in concentric ranks arrange heliostat with
Ranks at a distance are made to be minimized by the stop closer to ranks, to realize honeycomb fashion more or less by making continuous print ranks interlock
Arrange.Therefore, the heliostat of ranks is spaced apart with angle A, the heliostat of next ranks by by with one ranks
Those are spaced apart with A/2.
Pitch pattern in ranks can change, and also can change the distance between concentric ranks, but along tool
Have less than between ranks three times of spacing or less than line or arc directly radially in the range of the average arest neighbors of heliostat
Each ranks of the average headway of three times of distance have the repeat patterns of many heliostats.This makes ranks when random observation
It is well defined and obvious.Note that field 1 described herein example be the layout patterns retrained by line or arc clearly
Example.There is more unconspicuous example, but go through geometrical constraint at display, the overlap of the most parallel arc.Constraint
Simplify the degree of freedom in optimization, and allow to obtain overall situation best allocation in simplifying constraint.The method herein proposed and
Before result must obtain overall situation optimum not ensured the optimization method of offer global optimum certainly scheme by employing,
So that the non-geometric constraint realizing heliostat is arranged, it has been observed that for not previously being considered determining useful certain of a layout
A little optimized cost functions achieve the level more optimized.These include cost function (such as season income or the season of complexity
Electricity output) or simpler cost function, the ground from the point of view of favourable near the such as receiver from tower is covered and (is such as being connect
In 0.5 times of the receiver height of receipts machine).
Figure 66 is shown in which that the spacing of the heliostat 722 as indicated by 726 is along some arc substantially uniformly (edge
Arc equidistant) and the most uneven on other arcs 730 as indicated by 728 (three close to followed by gaps;Weight
The section of field layout 720 again).Drawing arc 728 is to illustrate that heliostat is positioned on arc or line, even if its spacing is uneven
's.Further, the figure shows concentric or parallel arc.These concentric arcs can be substantially circular, ellipse or avette
's.Figure 67 show the embodiment according to open theme away from tower and be reflection optimization field layout from figure 23 above
The region of field 220.This is that wherein heliostat 747 seems to be fairly close on straight line 744 or arc 742 but goes through
Show its example not having.220 with the difference of field 720 be can not by line or arc or particularly parallel lines or with
Heart arc be positioned so that its extend through be spaced from each other less than the heliostat being adjacent to or on online or arc average (recently
Adjacent) at least 20 heliostats of three times of spacing.
Can be from needing how much information to characterize from the viewpoint of the position of heliostat as the settled date fallen online or arc
The sign of mirror.In an identical manner and due to by enabling heliostat position constraint to reduce optimized dimension in line or arc
Same cause, compared with unconfined one, the layout of constrained optimization to be defined needs less information (to assume without retraining
The method optimized utilizes the unrestricted of the placement of heliostat freely and not produce the inside limit may being reflected in optimized results
System).In other words, the layout of constrained optimization has the entropy than a unconfined less information or less.Straight in order to detect
The algorithm of the existence of other curves of line or such as arc has many, and by image procossing or the technical staff in compression of images field
It is best understood by.Such as, the algorithm for image procossing and compression of images is developed well, and can be used to detection curve
And determine the curve representing the least complicated type needed for the layout of field.Once it is detected, can be for parallel condition test song
Line.The number of the number of curve and the heliostat fallen on curve position can be quantified.If the position on curve and curve
Put aspect and characterize the quantity of information needed for the close position specifying heliostat in terms of its independent coordinate of the quantity of information needed for the layout of field,
Then can not be said to be on curve or line by heliostat, because using this term in this manual.Therefore, in order to make the settled date
Mirror falls on curve or line, needed for the minimal information amount needed for the position on line or curve that represents should be than representing position independently
Little about twice or more, it is assumed that the phase equally accurate in two kinds of expressions.In order to provide simple examples, if 1250 heliostats are with phase
Deng number distribution on 25 curves, each cubic polynomial that is represented by, then can be with 3 numbers for each curve
(number) 50 numbers or 1325 of the heliostat and on each curve characterize its position illy.Not join
Its position is specified to would be required to 2500 numbers in the case of examining line or curve.
