Setup Measurement Site

Introduction

WindFarmer: Analyst has the concept of a measurement site which can be of different types: Mast, Lidar, Sodar, Reference Station and a Reanalysis Node.

These snippets show how to setup a measurement site from external files. WindFarmer: Analyst also allows you to create frequency and/or turbulence distributions from time series data in the project. For that see Measurement Campaign

Add a mast

// Define the name of the mast
string mastName = "My Mast";

// Define mast location
Location mastLocation = new Location(324259, 6674517);

// Create a mast object
Mast mast = new Mast(mastName, mastLocation);

// Add the mast to the workbook
Workbook.Climate.MeasurementSites.Add(mast);

Add other measurement sites

// Create a lidar
Lidar lidar1 = new Lidar("Lidar 1", new Location(324350, 6674650));

// Create a sodar
Sodar sodar1 = new Sodar("Sodar 1", new Location(324420, 6674300));

// Create a reference station
ReferenceStation refStation = new ReferenceStation(
    "Airport", 
    new Location(300500, 6675000));

// Create a reanalysis node
ReanalysisNode merra1 = new ReanalysisNode(
    "MERRA_NW",
    new Location(300000, 6600000));

// Add measurement sites to the workbook
Workbook.Climate.MeasurementSites.Add(lidar1);
Workbook.Climate.MeasurementSites.Add(sodar1);
Workbook.Climate.MeasurementSites.Add(refStation);
Workbook.Climate.MeasurementSites.Add(merra1);

Load a tab file

// Can be loaded from folder next to the workbook using relative path.
FrequencyDistribution FD =
    Toolbox.MeasurementCampaign.CreateFrequencyDistributionFromTabFile(@"Folder\Demo.tab");

// Save a frequency distribution to a measurement site at 28m AGL. This will generate the 
//  wind climate automatically.
Toolbox.MeasurementCampaign.SaveDistribution(
      Workbook.Climate.MeasurementSites["My Mast"],
      FD,
      "Demo FD", 
      28.0, 
      true);

Load a wti file

// Can be loaded from folder next to the workbook using relative path.
TurbulenceIntensityDistribution TI =
    Toolbox.MeasurementCampaign.CreateTurbulenceIntensityDistributionFromWtiFile(
        @"Folder\demo.wti");

// Save a turbulence intensity distribution to a measurement site at 28m AGL.
// This will generate the wind climate automatically.
Toolbox.MeasurementCampaign.SaveDistribution(
      Workbook.Climate.MeasurementSites["My Mast"],
      TI,
      "Demo TI", 
      28.0, 
      true);

Import a sensor point resource

// Get the wind climate created from saving a distribution.
WindClimate windClimate = Workbook.Climate.MeasurementSites["My Mast"].WindClimates[28.0];

// Load sensor point resource to wind climate object (windClimate).
// Requires full path to file
Toolbox.ImportPointWindResource(
    @"C:\TestData\Demomast_MastHeight.wrg",
    windClimate);

Import a RSF

// Get the wind climate created from saving a distribution.
WindClimate windClimate = Workbook.Climate.MeasurementSites["My Mast"].WindClimates[28.0];

// Load a discrete wind resource to wind climate object (windClimate). Requires full path
Toolbox.ImportDiscreteWindResource(@"C:\TestData\Demo_discrete.rsf", windClimate);

Import gridded wind resource

// Get the wind climate created from saving a distribution.
WindClimate windClimate = Workbook.Climate.MeasurementSites["My Mast"].WindClimates[28.0];

// Load gridded wind resource to wind climate object (windClimate). Requires full path
Toolbox.ImportGridWindResource(@"C:\TestData\Demo.wrg", windClimate);
