WIND TURBINE ACOUSTIC NOISE AND SHADOW-FLICKER MITIGATION

摘要

An integrated wind turbine acoustic-noise and shadow- flicker recognition system, comprising monitors located at nearby locations and base-units installed in each wind turbine, is described. The system comprehensively addresses neighbors' concerns with potential sound-and flicker-based nuisance emissions. Each monitor includes a computer processor; a microphone and light-monitor; a two-way communication system for interaction with the base-unit; and a set of indicator-lights. Each base-unit includes a computer processor; a two-way communication system for interacting with local monitors; plus a display, data-ports, and programming interfaces. Collectively, computer processors in the monitors and base-units jointly assess acoustic, optical, and turbine operating data to signal a mitigation event. The methods used to determine a mitigation event are based on a unique signature-recognition methodology that relies on analysis of data received at both the turbine and at the monitored location.
