BirdScan MV1

Adaptive wind park managment

The monitoring system allows the adaptive management of wind parks to mitigate collisions of migratory birds and bats with wind turbines. If the collision risk exceeds the specified threshold, the system alarms the plant operator or can automatically communicate with the wind park controls.

General description

BirdScan MV1 is a compact radar system for the continuous monitoring and risk management in wind farms. It uses a vertically directed conically shaped wide aperture beam to collect a rich set of information of the biomass in the sky. It does automatic real time quantification and classification that is used in the adaptive management algorithm to compute the collision risk, considering also environmental conditions like visibility and wind speed.

Comparison to traditional bird-radars

Traditional horizontally or vertically rotating bird-radars only illuminate a target for a fraction of second and wing-flapping pattern cannot be recorded. Therefore non-bird echos like insects cannot be properly excluded. In traditional rotating radars the surveyed volume is generally not well-defined and therefore computation of MTR is problematic.

Wing-flapping pattern

The wing-flapping pattern is recorded and can be extracted automatically, here a continuously flapping bird with 8 wing-beats per second.


Wind Turbines

Like for any radar, rotating blades within the measurement beam would produce strong disturbances. For good measurement results, the radar should therefore be placed with a minimum distance of approx. 150 m to the turbine center.

Offshore deployment

The system can be deployed offshore on any platform. It is therefore protected for offshore conditions. See following images:

Offshore deployment in container

Option 1: container

Server and processing module protected in a container; radar antenna on top of container protected by a small radome.

Offshore protection radome

Option 2: large radome

Standard compact MR1 system protected by a larger Radome (approx. 1.5 m width * 1.6 m height).

MT1 on research platform

Option 3: research platform

BirdScan MT1 has been used by Schulz et al. (2014) at Alpha Ventus. It was situated at the FINO1 research platform. Offshore deployment therefore has been proven successful.

High quality offline-analytics

The BirdScan radar systems can reliably detect even small passerines, bats and insects. Hundreds of thousands echos per month can be recorded. To leverage the full potential of this data, detailed off-line analytic can be performed.
