Wind resource data

Where can I find wind resource data for countries such as Oman in SRW format? Or How can I change other type of data to SRW format? and Which type can be converted to SRW format?

Unable to download wind data using the "Download a wind resource file from the online NREL WIND Toolkit" option

I am encountering the following error:

"Retrieving data at lattitude = 39.74 and longitude = -104.99
Downloading data for 60m hub height.
Failed to read downloaded weather file C:\Users\smadala/SAM Downloaded Weather Files/lat39.74_lon-104.99__2013."

Any guidance on how to proceed is much appreciated. Thank you!

FMU export of SAM

Hi,

Is there any possibility that we can export SAM simulations as a functional mockup unit (FMU) export like EnergyPlus? I appreciate your help.

Best regards,
Mohammad

Running the C program of the wind module

Hi,

I have been trying to run the SAM's C code generated in command prompt. I have used the following command

gcc -o Golden Golden.c

Golden is my file name. However, I have received the error of "undefined resources" which is mostly related to the sscapi.h header file.
Could you please help me about this?

Thanks,
Mohammad

Accessing windpower module output in Python

I've recently noticed that retrieving the 'gen' array - Total electric power to grid' is much slower than earlier releases of the SDK. The change actually occurred somewhere between Build 174 and 180. Is there a better way to access this data or is it due to some internal change?

I'm using Python 2.7 and the relevant code is:


clock_start = time.clock()
module = ssc.Module('windpower')
print time.clock() - clock_start
farmpwr = self.data.get_array('gen')
print time.clock() - clock_start

entering 35040 wind_resource data but SAM outputs 8760 generation

Hi Paul,

My goal is to output system generation (or system power) given wind_resource data as input to SAM. I am giving 35040 wind_resource data but the output is 8760 generation. The code is:

ssc = PySSC()
ssc.module_exec_set_print(0)
data = ssc.data_create()
module = ssc.module_create('windpower')

wind_resource = ssc.data_create()

How to find wind data for Brazil in .srw format

Hi,
I would like to know where I find wind data information for Brazil, on the website at NREL you have only for the US I am using SAM to do an academic job and would like to simulate a wind project located in Brazil, and I can not find data in .srw format as SAM requests.

Thank's fot the moment ..

Thomas.

Turbine tower cost estimation

Hi, I have some questions regarding turbine tower cost determined by SAM cost database.

Based on the SAM documentation review, it looks like that tower cost is included in turbine cost.
If it is, as SAM use a fixed cost per turbine rating based on 2015 installed cost for offshore turbine, change in tower cost for different hub height will not be captured.
It is also found that change in hub height does not affect substructure and foundation cost when the jacket type substructure is selected.
