Introduction
Wind analysis using radar data involves using the Doppler effect to measure wind speed and direction by detecting shifts in the frequency of reflected radio waves, which are affected by the movement of atmospheric particles. Doppler weather radars send out radio pulses that reflect off precipitation particles or other aerosols in the atmosphere.
Frequency Shifts: The radar measures the change in the frequency of these reflected pulses
Velocity Calculation: This frequency change indicates the velocity of the particles toward or away from the radar, which is then used to determine the wind speed and direction
Radar data is crucial for real-time monitoring of storms and identifying features like bow echoes associated with strong winds.

This tracks the power plant interference with radar data depending on use case parameters such as the angle, frequency, wind speed, and impacted energy production.
Input | Definition |
Angle (°) | Depending on the selected wind turbine and the selected time range, all the wind speed samples collected by the system are grouped by wind direction sectors of 30° size, for example from [0° - 30°],[30° - 60°],[60° - 90°], and all the way up to [330° - 360°]. |
Frequency(%) | Represents how many samples of wind speed we have per wind direction sector. It's a percentage because it's compared to the total amount of samples we have for the selected wind turbine in the selected time range. |
Wind Speed (m/s) | Average wind speed of all the samples per wind direction sector. |
Energy (MWh) | An equivalent amount of energy, which represents the ideal possible amount generated by the wind per sector (it is calculated using the wind speed samples contained in each wind direction sector). |
