1. A system for monitoring and controlling the deflection of turbine blades of a wind turbine, the system comprising:
- a passive position detecting apparatus disposed on a wind turbine, wherein said passive position detecting apparatus is configured to acquire and transmit data relating directly to a position of at least one of a plurality turbine blades of said wind turbine; and
,a controller configured to receive said data from said passive position detecting apparatus and compare said data to a known position reference to determine turbine blade deflection.

Abstract
A system is disclosed for monitoring and controlling the deflection of turbine blades of a wind turbine. The system includes a passive position detecting apparatus and a controller. The passive position detecting apparatus may be configured to acquire and transmit data relating directly to a position of at least one of the turbine blades. The controller may be configured to receive the data from the passive position detecting apparatus and compare such data to a known position reference to determine turbine blade deflection.
