Abstract

The invention relates to systems and methods for real time wind farm optimization. Drone(s) equipped with various instruments are utilized to measure wind speed and direction for optimizing a wind farm. The equipped instruments of one drone may comprise wind speed and direction measuring devices, an infrared camera, a solar cell, anti-aliasing filters and any other instruments. The solar cell is installed on the top of the drone, and the other instruments are attached to the bottom of the drone. For a wind farm, one or more drones may be utilized to optimize the wind farm. The drone(s) may be configured to navigate around the wind farm and the drone(s) can measure wind speed and direction, and store wind data. The turbines can autonomously respond to changes in the wind speed and direction, and the drone(s) will send all the wind data and tracked animal data to a control center and the control center can utilize the data to develop more precise wind distribution maps for load estimation models, predict the future site level wind conditions and build a developed model of animal habits and patterns.

SYSTEM AND METHOD FOR REAL TIME WIND FARM OPTIMIZATION WITH AERIAL DRONE(S)

BACKGROUND

The invention relates generally to systems and methods for real time wind farm optimization, and more particularly to using aerial drone(s) for real time wind farm optimization.

For measurement of wind speed and direction, various instruments, such as an anemometer, a wind vane or a Light Detection and Ranging (LIDAR) system, etc. may be implemented. However, in the art, these instruments usually need to be installed on the wind turbine and require the wind turbine to be shut down for regularly inspections. What’s more, the anemometer is installed on the top of a turbine nacelle and behind blades, and is thus severely waked by the rotating blades, which will result in the measured wind speed being inaccurate.

DETAILED DESCRIPTION

To solve the above-mentioned problems, one or more drones equipped with various instruments are utilized to measure wind speed and direction for optimizing a wind farm.

The equipped instruments of one drone may comprise wind speed and direction measuring devices, an infrared camera, a solar cell, anti-aliasing filters and / or any other instruments. The solar cell is installed on the top of the drone, and other instruments are attached to the bottom of the drone. The wind speed and direction measuring devices may comprise ultrasonic wind speed and direction detectors, or an anemometer and a wind vane, or other similar measuring instruments. The ultrasonic wind speed and direction detectors have calibration functions and the calibration function will necessarily be applied to offset eddy currents caused by blades of the drone. The infrared camera can track animals in order to avoid potential risks for the drone. The infrared camera has a function of the laser ranging and the laser ranging can track the animal once it has been spotted by onboard image processing. The solar cell can provide the running power to the drone in order to delay the recharge cycle time. When the drone hits a minimum level of power, the drone will return to a docking station to recharge. Anti-aliasing filters will ensure the drone cannot be taken control by external sources.

For a wind farm, there are multiple wind turbines. In order to accurately measure the wind speed and direction and optimize the wind farm, one or more drones equipped with the instruments may be utilized in the wind farm. There will be a control center in the wind farm to remotely control and view all the turbines and there will be support staff(s) in the control center.
