Wind turbines (WTGs) offer a wide range of input data to cover any use case. Input data varies between Shoreline Design Construction and Shoreline Design O&M. This page covers all the available Shoreline Design Construction inputs, describing their use and limitations.
For O&M, see the Wind turbine input data: O&M page.
TABLE OF CONTENTS
Members
This tab displays a list of all WTG names and locations.
Click on a wind turbine name in the list to edit the location and define the grid start date, which is when the wind turbine is hooked up to the grid prior to entering production mode.
Add additional WTG instances by clicking + Add instances.
Parameters
| Parameter | Required | Description |
|---|---|---|
| Rated power | x | Maximum power the WTG can produce. |
| Nacelle | x | Height of the installed nacelle or hub. Used along with wind speed to model weather windows. |
| Maximum number of technicians in asset | Number of technicians who can enter the asset at any one time. Used for commissioning tasks. Leave this empty or enter | |
| Remarks | Optional comments related to the asset. |
Weather criteria
| Parameter | Required | Description |
|---|---|---|
| Significant wave height operational criteria | Maximum wave height at which the WTG can operate. Above this wave height, the WTG will not produce power. Create a matrix for more detailed criteria. See the weather matrix page to learn more. Note: Only necessary for floating WTGs. |
Power curve
This graph displays the WTG’s produced power as a function of wind speed.
The power curve is used alongside the weather data applied to the asset in the Weather tab to simulate the WTG’s energy output. Weather data is taken from the closest reference height to the nacelle height and extrapolated to match the nacelle height using the wind profile.
You can import a custom power curve using a CSV file:
- Click Upload CSV file at the bottom of the graph.
- Select a Column delimiter and Decimal delimiter option according to how your CSV file is formatted.
- Click Select CSV file.
- Navigate to the file on your computer and double click it.
- Click Upload at the bottom right.
Info: See the How to create CSV files for import page for details on how to format your file.
Tasks
Model the transportation, installation, and commissioning stages of assets using tasks and dependencies. Our Task dependency modelling page provides details on how to configure this part of your asset.
Weather
Select the weather data for use in your simulation. Import custom weather data or use ERA5 data provided by Shoreline. See our How to add weather files to a case page for further information.
Power law exponent for wind profile
The power law exponent is the input for the wind profile used to extrapolate wind speeds at various reference heights, such as the nacelle height.
By default, the value is 0.11, which is typical for offshore conditions.
You can apply the same value across all assets by clicking Apply everywhere.
Note: Applying the same power law exponent everywhere only affects existing assets and will not affect assets added to the case subsequently.
