We scrutinize separate components of the model and develop new models when the evidence shows there is a deficiency. Our validation exercises and model developments are documented in the publication section. WindFarmer: Analyst software provides an efficient task-oriented interface that takes you smoothly through the analysis process.
You can:. To find out how WindFarmer: Analyst can meet your needs for wind farm development design, please contact us. Learn how the most advanced models in WindFarmer give the most accurate energy predictions. The red line on the map represents the boundary of the site within which the turbines are placed. Additional objects can be added or existing ones can be moved or deleted.
This will be explained in the later tutorials. The legend on the right describes the extent of each colour band. The bands can be modified for higher or lower resolution but for now we will leave them at their default settings.
Step 3. The graphing toolbar will also now be activated. Now close the wind rose diagram to return to the map view. Wind Flow Modelling WindFarmer can calculate how the wind climate will vary across a site — a process known as wind flow modelling. To start the process, you must input wind data for a reference point on the site — usually the anemometry mast where it was measured.
This is typically a TAB file or a mean wind speed value from a wind map. WindFarmer provides a choice of wind flow models. It has integrated control of WAsP, the industry standard wind flow modelling software package. If you prefer, it is also possible to import the results of external wind flow models and CFD packages in the form of WRG files.
For example, rotor diameter, hub height, power curve and so on. It is currently showing the specifications of the kW turbine used in the Demosite workbook. You can enter your own turbines and save them into a library for use in future projects. It is possible to have a mixture of several different types of turbine in the same workbook.
Notice that currently no output has been calculated for the turbines and so each one has a net yield of 0 MWh. You will see on line 18 that the estimated net output from the wind farm, after allowing for the losses shown, is You may have a different value here if you have moved some of the turbines. The Eddy Viscosity wake model is an axisymmetric CFD model which has been extensively validated in wind tunnels and against real operating wind farms, with impressive results. There are many ways of looking at the results generated by WindFarmer — these can be generated in the form of spread sheets or graphs and added to the final report as you choose.
A window will open which allows you to make various choices. The Information pane to the right also indicates the overall net yield and array efficiency of each turbine.
For clarity of the mapping screen, deselect the Wind Energy checkbox if you currently have it checked. Results are given for a range of exceedance levels, including P50, P90 and P The DIBt classification standard is also supported.
The example output below shows how the turbulence intensity at the site will exceed the IEC limit for the chosen turbine class. Flow and Performance Matrix Typically, the results of energy calculations are given as the average annual performance. This allows further analysis of the behaviour of the wind farm, and an understanding of details such as the power curve of the entire farm. You can choose either to investigate the visibility of the turbines from various viewpoints or create a map overlaid on the site which shows how many turbines will be visible from any location.
Step 4. ZVI of Radar To avoid interfering with the performance of nearby radar stations, it may be necessary to adjust the location of turbines. WindFarmer can test for a line of sight between a radar station and your turbines, and show where it will be safe to make an installation. If you are using a licenced version of WindFarmer, you will also be given the opportunity to save the workbook, which will include the results of this calculation.
Click on the legend tab in the control bar panel to reveal the meaning of the colour bands. The colours indicate how many turbines are visible from each point on the map.
Cumulative Impact WindFarmer can assess the cumulative impact of several wind farms. Results can be presented for each wind farm separately, or for the combined impact of all the farms. It is possible to get detailed information on visual impact anywhere in the site. This will open a dialogue box similar to the one shown below: This gives information as to how much of the wind farm is visible from that point and whether the hubs as well as the tips are visible. It also describes how much of the view in degrees is occupied by the wind farm, both horizontally and vertically.
WindFarmer contains tools to help you model the noise effects of your wind farm, and to find a layout which will meet the acceptable limits. When the calculation is complete you will see a map representing the sound pressure level of the noise from the turbines across the site.
