Method of stabilizing a power grid and providing a synthetic aperture radar using a radar wind turbine

摘要

A blade mounted radar system comprises a wind turbine having a hub and blades extending therefrom; a radar antenna configured to transmit and/or receive a radio frequency (RF) signal; and a processor in electrical communication with the radar antenna and configured to generate the RF signal for transmission and/or to process the received RF signal. The radar antenna is affixed to one of the blades of the wind turbine such that relative motion is defined between the radar antenna and a target within a line of sight of the radar antenna. The problem of the ground based radar line of sight being obscured by the wind turbine is mitigated in this setup, as radar and turbine coexist in the same structure. Improved performance and additional capability are enabled by elevated installation and vertical SAR imaging capability. Doppler capabilities are extended using known motion of the antenna relative to stationary objects.

1. A method for maintaining a stable power supply in a power grid during a weather event comprising the steps of:
attaching a radar sensor to at least one blade of a wind turbine; transmitting Doppler radar signals from said radar sensor; receiving, at said radar sensor, reflections of said Doppler radar signals to generate weather-related information; communicating to said power grid in communication with said wind turbine, notification of a detected weather event based on said weather-related information.
