Wind rose

The Wind rose widget provides a visual representation of wind direction and nacelle position for a selected turbine over a specific time period. Positioned at the center-left of the screen, this chart helps you analyze directional wind patterns and nacelle alignment, offering insights into turbine performance and efficiency.

The chart displays wind direction and nacelle position in degrees, covering data from midnight (12 midnight) to the current time. Each segment of the wind rose represents a directional band, and the chart uses color-coded sections to indicate wind speed ranges and nacelle orientation.

You can interact with the chart by hovering over any segment to view detailed statistical insights. The tooltip provides comprehensive information for the selected directional band, including:
  • Date: The specific date or time period for which data is displayed (for example, 01-Mar-2023).
  • Wind Speed Range: The minimum and maximum wind speeds for that segment (for example, 5–10 m/s).
  • Direction Band: The directional range represented by the segment (for example, 260°–270°).
  • Data Points: The total number of observations within the selected speed and direction range (for example, 22 values).
  • Directional Share: The percentage of all recorded values that fall within this directional band (for example, 5.8%).
  • Average Wind Speed: The mean wind speed calculated for this directional range (for example, 6.6 m/s).
  • Speed Distribution: The percentage of all recorded data points across all directions that fall within the same speed range (for example, 81.4%).

This interactive design allows you to quickly identify dominant wind directions, nacelle alignment trends, and speed distribution patterns, which are critical for optimizing turbine performance.
