Wind Turbine Machine Models

Wind Turbine Machine Models

In the growing field of wind energy, incorporating wind turbine models into transient stability analysis is essential. Induction and synchronous machines are the primary models used, with induction machines being prevalent due to their simplicity and reliability.
Induction machines interact through the rotating magnetic field generated by the stator and the rotor. The key parameter is slip, which is the difference between synchronous speed and rotor speed relative to synchronous speed. Slip is...

Turbine-Governor Control

Turbine-Governor Control

Turbine-governor control is crucial for maintaining power system stability by balancing turbine mechanical power output with electrical load demand. This mechanism ensures that generator frequency and rotor speed are within acceptable limits during load variations. Turbine-generator units store kinetic energy due to their rotating masses; this energy is released to meet the load requirement when the load increases. The electrical torque of turbines rises to meet the demand, whereas the...

Design Example: Calculating Safe Diameter for Wind-Exposed Disc

Design Example: Calculating Safe Diameter for Wind-Exposed Disc

Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...

Area of Science:

Wildlife Conservation
Renewable Energy Impacts
Machine Learning Applications

Background:

Bat fatalities at wind turbines are a significant conservation concern.
Current monitoring methods, like thermal imaging focused on the rotor swept area (RSA), struggle with accurate fatality detection.
Few bat fatalities are documented compared to extensive video recording efforts.

Purpose of the Study:

To evaluate a novel ground-based thermal camera system paired with machine learning for detecting bat fatalities at wind turbines.
To determine the efficacy of this system in tracking and identifying bat carcasses below the RSA.

Main Methods:

Deployed two thermal camera systems on wind turbines in southern Texas.
Utilized machine learning algorithms to analyze over 274,051 bat tracks from video recordings.
Performed manual review of algorithm-identified potential fatalities and correlated with ground-searched bat carcasses.

Main Results:

Machine learning algorithms identified 189 potential bat fatalities from 274,051 classified bat tracks.
Manual review confirmed 23 tracks as possible fatalities occurring within the camera's field of view.
Confirmed fatalities aligned with ground-searched bat carcasses and estimated times of death.

Conclusions:

The thermal camera system and machine learning algorithm effectively process extensive video data to identify suspected bat fatalities.
This system can direct human searchers to specific turbines, minimizing manual search efforts.
The technology holds potential for estimating offshore wind turbine-related bat fatalities where traditional methods are not feasible.
