Full automation for all WAsP users [Repost]

Wed, 13 Mar 2019 10:52:21 +0000

This message was originally posted on 2018-01-05. The text became unavailable for some reason, so I am re-posting it now.

Hello automators,

Happy New Year for 2018.

I wonder if you all noticed the interesting news which accompanied the release of WAsP 12 last
month?

WAsP 12 is being released With a new licence, called the "suite" or "bundle" licence. It's different
because it includes WASP, WAT and WAsP Engineering, and it's now an annual subscription.

What's more, the new licence allows by default full developer access to the WAsP object model. You
no longer need to buy a special developer licence.

This means that if you develop some custom application or spreadsheet which uses the WAsP model
Without the GUI, then you can share that with all WAsP users in your organisation - or indeed with anyone in the world. You are no longer limited to scripts executing within the GUI context.

I'm aware that there is no complete documentation for the WAsP Object model API, but if you're
already working with scripts, then you're most of the way there already. I'll be happy and interested to
answer any questions here in the forums.

We really hope that this will let people make use Of the software in new and powerful ways.

Best wishes, Duncan.

Difference between sectoral and cumulative gross AEP?

Wed, 16 May 2018 12:09:01 +0000

Dear all,

while experimenting with a power curve that is shut down (power = 0) for a certain wind speed range I have come across a puzzling issue: The gross AEP as calculated by IRveaProductionRose.SectorForIndex(SectorIndex).GrossContribution for a given sector is greater than the sectorial AEP calculated from IRveaProductionDistribution.ProductionForSpeed (of course after accounting for the sector frequency).

In my example I used a power curve that cuts in at 19m/s. For sector 2, the calculated .ProductionForSpeed values are:
19 m/s: 15705 kWh/y
20 m/s: 2099 kWh/y
21 m/s: 237 kWh/y
22 m/s: 23 kWh/y
23 m/s: 2 kWh/y
and zero above 23m/s. The sector frequency is 7.497%.
This results in a gross AEP of (15705+2099+237+23+2)*0.07497 = 1354.4 kWh/y, but the .GrossContribution is reported as 3215 kWh/y, almost 40% higher.

For other sectors with higher wind speeds, the difference is only in the order of some 20%, but .GrossContribution is always greater than the sum of the non-zero .ProductionForSpeed bins.

When I use a non-curtailed power curve (cut-in at 3 m/s) the difference is less than 0.2%, for high-yield sectors even down to 0.01%.

I always thought the AEP is simply the sum (or integral) of the production values determined in each wind speed bin (based on the power curve and the bin frequency), but apparently this is not the case. Could someone please explain in detail how AEP is calculated?

Thanks in advance!

Script fails for more than two wind farms

Wed, 10 May 2017 13:00:27 +0000

Dear all,

I have a workspace with three identical projects, each consisting of a 'Terrain analysis (IBZ)', a 'wind farm' and a GWC (plus some notes). I also have a script, which iterates through the projects and calculates the respective windfarm using the DoAllPossibleCalculations method.

The weird thing is that the wind farm calculation works well for the first two projects, but fails for the third (and all further) wind farms. More specifically it fails to calculate the wake losses and net AEP, while the free AEP is calculated for each turbine and the wind farm.

By default, each wind farm is calculated by issuing WindFarm.AsICalculatingHierarchyMember.DoAllPossibleCalculations(False). This works as expected for the first two projects/wind farms. However, in the third project nothing happens. I then check the properties of WindFarm.AsICalculatingHierarchyMember.CalculationByType(ectWakeLosses). In the third wind farm I find that:
.Status = 3 (i.e. echmsResultsDirtyCanRecalculate)
.AreResultsDirty = True
.CanCalculate = True
.AreThereResults = False

However, when I then run the WindFarm.AsICalculatingHierarchyMember.CalculationByType(ectWakeLosses).Calculate method immediately after checking these variables, still nothing happens, and the variables keep the same values a as before.

I have no clue what happens here and how to resolve that. As I said, the three projects/windfarms are identical (checked this by exporting the projects to w.p files and compared the resulting Inventory.xml files, which differ only in the ID strings and the references to the .tmp files). Why does the WindFarm refuse to calculate in the third project?

I also checked to put all three farms inside of one project, but the result is the same, so I suppose that this issue is related to the wind farm calculation method.

Any suggestion is welcome. Thanks in advance!

How can I automate WASP 11 with developer's license?

Mon, 22 May 2017 10:45:41 +0000

Hello.

We have bought developer license.

And, we want to externally use WAsP sofware using other programming language such as MATLAB, VBA, C++, etc.

We try to calculate AEP at different turbine sites repeatedly without doing it manually in GUI interface.

Hence, I wonder if we can get any guideline or sample for it.

Thank you.

WAsP script library?

Fri, 03 Feb 2017 10:50:23 +0000

Hi,

I have a 17 exactly defined positions project. I aim to pick the best combination of 6 out of them. I would like to script a process to evaluate all possible combinations (12376). Is that possible? Is there some API in WAsP? Where can I found some library?

Thanks in advance!

Simple sectorwise site corrections text output script

Tue, 06 Dec 2016 09:34:39 +0000

Hi everyone,

Yesterday I hacked up a quick script for a colleague. It's simple and useful, so I thought of just posting it here in case anyone finds it helpful. I'll just paste the script source in here.

The script finds all the turbine sites in the project root and writes a text file of sectorwise corrections in a way which is convenient for some other progam to read and use.

Best wishes, Duncan.

Automate conversion from .WRG to .GRD/.ASC

Thu, 27 Oct 2016 17:22:35 +0000

Hi!

I'm aware of WAsP Utility Program "rsf2grd.exe" (from versions prior to WAsP 10) to convert the WRG to the GRD format or even XYZ format.

I'm looking for a way to perform the same conversion in a Linux environment.

Is there any further documentation on how the rsf2grd tool works or even a Linux port of the code?

Thanks

How to get the max Power?

Fri, 02 Sep 2016 13:35:27 +0000

Dear Wasp Community,

is it possible to write a command in the Html script to get the maximum of the Power for each turbine in the report view.

In detail, I want to get the value in kW at which each turbine has it´s maximum in the power curve. In Wasp you will find the data set for the power by clicking on "windturbinegenerator" on the left hand side in the workspace. The Power curve is poping up and then by clicking on data.

I guess that I first need to define the data set, maybe like see below:
Set WTG = Site.AsICalculatingHierarchyMember.CalculationByIndex(1).Associates.WindTurbineGenerator.Data.Power

as well as to add a new table and to calculate the maximum.

But do you have an idea how the correct Html comand needs to look like? I pretty much tested every combination and it wasn´t working out. I will appreciate it.

Cheers,

Windmueller

How to change the decimal place?

Fri, 16 Sep 2016 07:10:34 +0000

Dear Wasp community,

is there a Html command in the script which changes the decimal places in the report view e.g from 5,67 to 5.

In particular I would like to have the values for the Elevation without a decimal place. This is the Html therefore: "...Builder.InsertClosedTableDataHeaderRowElement "Elevation [m] a.s.l."
...Builder.InsertClosedTableDataElement Site.AsIWaspSite.Elevation..."

I hope you have an idea - will apreciate it.

Cheers

How to change the units?

Mon, 29 Aug 2016 13:43:26 +0000

Dear WASP comunity,

is it possible to change the unit from MWh into kWh in the report view? For example the script is showing for the Net Aep:

Builder.InsertClosedTableDataHeaderRowElement "Net AEP [" & DataFormatting.GetAepUnits(MaxPower) & "]"
Builder.InsertClosedTableDataElement DataFormatting.FormatAep(UnstructuredTurbineSiteGroup.SummaryResults.AepSumOfSectorsNet.Total, False, MaxPower)
Builder.InsertClosedTableDataElement DataFormatting.FormatAep(UnstructuredTurbineSiteGroup.SummaryResults.AepSumOfSectorsNet.Mean, False, MaxPower)
Builder.InsertClosedTableDataElement DataFormatting.FormatAep(UnstructuredTurbineSiteGroup.SummaryResults.AepSumOfSectorsNet.Minimum, False, MaxPower)
Builder.InsertClosedTableDataElement DataFormatting.FormatAep(UnstructuredTurbineSiteGroup.SummaryResults.AepSumOfSectorsNet.Maximum, False, MaxPower)
Builder.EndTableRowElement

I guess MWh is a kind of a standard unit for Wasp. Do you have an idea? I will appreciate it.

Best,
Windmueller

"Type mismatch" problem

Fri, 19 Jun 2015 13:52:41 +0000

Dear all,

we have a Reference Site with a Generalized Wind Climate calculated from an OWC, which calculates fine on most of our computers. However, one colleague in our French office encounters a 'Type mismatch. ' error when he does the calculation. Do you have any idea what might be causing this error? The exact error message is:

Could not process the menu action because ...
could not do all calculations for a member because ...
unable to perform all the pending calculations because ...
could not do the reference site calculation because ...
could not perform site assessment for a reference site because ...
the system reported that:
'Type mismatch.'

There must be some relation to the specific setup of this computer, since the same .wwh file calculate without error on most other machines. Thanks for any suggestion!

Suppressing the "Script is taking longer than expected" message

Mon, 03 Jan 2011 15:00:15 +0000

Is there a way to suppress or tame the "Script execution is taking longer than expected" message box? What is the criterion for this expectation?

Some of my scripts take sort of a long time to run, though not really "longer than expected". More often than not, WAsP brings up a "Script is taking longer than expected. End / Continue" message box, sometimes multiple times during script execution.

This box pops up on top of other applications, which is a minor annoyance. Also, the keyboard shortcut for the "End" option is "E", which I've accidentally pressed a few times, meaning the script was terminated and I had to restart it from scratch.

Any tips are appreciated!

Avoid graphical display upon GWC import

Fri, 17 Oct 2014 07:38:09 +0000

Dear all,

I'm struggling with an annyoing feature when I import a GWC from file to my turbine site. At the moment I do that as follows:

Call Workspace.ReEnableChangeRipples(True)
Set Member = TurbineSite.AsIHierarchyMember.Insertions.FromFile.ByClassID(ehmcWindAtlas).Execute(PartialGWCName,Nothing)
Call Workspace.DisableChangeRipples

When that code is executed, the imported GWC is automatically displayed in a new window in the right hand side of the main window. If you do repeated imports via script, the GUI will get cluttered soon, and closing these windows by hand is not what you really want when you are writing a script to automatize things...

Therefore my question: Is there a way to prevent that window from getting displayed after the import, or to close it automatically after is has been displayed?

Thanks for any suggestions!

Access air density parameter

Wed, 26 Nov 2014 11:24:43 +0000

I am working on a simple script to extract to Excel the results for a Wind Farm in WAsP 11.

Is there a parameter dictionary I could look up?

Access WAsP Wind Atlas in write mode

Thu, 09 Oct 2014 09:11:37 +0000

Hi @All,

I need to change some parameters iteratively via script to wind atlas class, related to several GWC object, with wasp (version 11.1), .

I see that there is a typecasting that allows it (CastRveaWeibullDistributionToRveaWeibullDistributionEditable)

and I can successfully change wind atlas properties (A,k) with it.

Unfortunately I cannot access sector frequencies, that seems to be a property of other objects, (I'm guessing the class: IRveaWeibullWindEditable).

Does anyone know which object to access and the proper typecasting method, in order to allow it being accessible in write mode by user ?

Thanks in advance for any hint!!

documentation

Wed, 30 Jul 2014 15:33:43 +0000

Hi there!
I know there isn't any documentation released by WAsP, but are there some descriptions for the codes. I'm trying to adjust some codes by myself and need to know for example whats:
- TypeCaster
- AsIXxx (eg AsIWindAtlas)
- CastMemberToMetStation(Member)

In my opinion its partly hard to derive the functions

For example: I get an error for
Set RotatingAtlas = ReportingAssistant.CastableSelectedMember.AsIWindAtlas
Set MetStation = RotatingAtlas.MetStation

"Wasp Object required: 'RotatingAtlas'

Can anyone help?

embedding a script

Tue, 29 Jul 2014 08:57:08 +0000

Hi, my name is newbie.
I simply need to know, how to embed a script into WAsP 11. I can see several utility scripts in the Tool menue but I would like to change and customize existing scripts. I tried hundreds of things and I don't see the woods for the trees and don't seem to find it in the forum as well.
Can anyone help, please?

Heatflux parameter access via script

Wed, 02 Jul 2014 14:55:27 +0000

Hi WAsP users!

I'm currently working with WAsP11 scripting. My license is not a standard one ( no developer licence) .

I would like to create a script that allows me to access the heatflux calculation parameters (and change them) in a generalized wind climate object, recalculate the wind atlas and store/export wind results.

The step has to be repeat more than once for multiple heatflux values and on several climates.

In this particular case study, the parent object that contains the climate is a reference site one.

The operation is of course possible via gui succesfully; I'm trying to make it automatic accessing the objects parameters, but a straight forward note regarding climate object is found nor under the "IRererenceSite" object description , neither under the "IWaspSite" object description.

Does someone have any idea about it?

Thanks in advance. Gianluca

Inserting from a file

Mon, 16 Jun 2014 19:48:40 +0000

Hello,
I am writing a script in order to automatize the manipulation of the workspace. In this context I want, to start with, to import a vector map and an observed wind climate.

My code is the following:

mappath="C:\Users\hdse\Documents\sea.map"
owcpath="C:\Users\hdse\Documents\Portugal.owc"

Set Project = ReportingAssistant.SelectedHierarchyMember
Set Cluster = Project.Insertions.New.ByClassID(ehmcTurbineSiteGroup).Execute
Set hmOwc = Project.Insertions.FromFile.ByClassID(ehmcObservedWindClimate).Execute(owcpath, Nothing)
Set MapSea = Project.Insertions.FromFile.ByClassID(ehmcVectorMap).Execute(mappath,Nothing)

The turbine site group is created successfully, but I have this error:

Script control reported the error: 
	Object required: 'Project.Insertions.FromFile.ByClassID(...)'

The last execution line attempt was for an unknown line number.
Script: 'essai1', version: 11.01.0001

The problem is coming from the file insertion, but I could`nt find the mistake.
I hope you will be able to help me
Thank you !

Hi,

I've heard that the scripting has changed quite a bit from WEng 2 to WEng 3.

Are there any plans to release a new version of the scripting documentation (or will I have to learn from looking at the supplied scripts)?

Thanks

Calculations through Excel and .was9 scripting

Mon, 02 Sep 2013 09:45:07 +0000

Hello!

I'm currently researching different methods to develop an iterative optimization script for various variables in WAsP.

The initial plan was to control the WAsP calculation machine through VBA and Excel. I am now able to manipulate the workspace freely.

The problem is that I can't Calculate anything through VBA. It gives the error message "the available license does not allow WAsP calculations". I assume the WAsP program unlocks the WaspMachine when you start it. Is there any way around this?

If not, I have a few questions about .was9 scripting.

Can you update excel cells in a long running loop and observe the changes immediately?

Can I add additional procedures and functions to the script? Can I include classes?

How to automate a few things

Wed, 20 Feb 2013 16:18:48 +0000

Hi, I'm looking for ways to automate the following within WAsP:

1. Update the analysis heights of each WRG and RSF automatically rather than manually changing the height of each.

2. Export all production and wake output reports automatically as opposed to manually exporting them in HTML/Word one at a time.

3. Is it possible to have the UTM coordinates pulled from a TAB file and have those automatically filled in for the met station and point file?

Any ideas how to do these are welcome. Thanks in advance!
