Wind Turbine Machine Models01:24

Wind Turbine Machine Models

600
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...

Open and closed-loop control systems01:17

Open and closed-loop control systems

1.7K
Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...

Lifecycle of Erythrocytes01:22

Lifecycle of Erythrocytes

5.2K
Erythrocytes, also known as red blood cells, constantly move through blood capillaries. As a result, they damage their plasma membrane due to the continuous friction. Typically, after 100 to 120 days, erythrocytes become rigid and fragile as they wear out. As they pass through small vessels in the spleen and liver, they can get trapped and break apart into fragments.
The resident phagocytic macrophages deal with these damaged cells by engulfing them and separating their globin and heme groups....

Turbine-Governor Control01:17

Turbine-Governor Control

954
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...

Three-Winding Transformers01:19

Three-Winding Transformers

713
Three identical single-phase transformers can be configured to form a three-phase transformer connection, which involves high-voltage and low-voltage windings. The high-voltage windings are denoted by capital letters A-B-C, while the low-voltage windings are labeled with lowercase letters a-b-c, representing their respective phases. This notation helps distinguish between the high and low voltage sides of the transformer.
In the per-unit equivalent circuit of a grounded Y-Y three-phase...

Recycling Endosomes and Transcytosis00:58

Recycling Endosomes and Transcytosis

3.6K
The recycling endosome, also known as the endosomal recycling compartment (ERC), is a part of the slow-recycling process of the endocytic pathway. Molecules internalized through receptor-mediated endocytosis are either degraded in the lysosomes or are recycled to the plasma membrane through the fast- or slow-recycling route.
The recycling endosome is not a single organelle but an extensively tubulated network of recycling pathways. It functions in storing molecules or transporting them across...

Area of Science:

  • Materials Science
  • Environmental Science
  • Chemical Engineering

Background:

  • Wind turbine blades, predominantly composite materials, pose end-of-life management challenges despite high recyclability.
  • Transitioning the wind energy sector to a circular economy necessitates advanced recycling for high-quality secondary materials.
  • Current practices lack scalable and sustainable solutions for managing composite wind blade waste.

Purpose of the Study:

  • To assess the environmental impact of producing recycled glass fibre and thermoplastic (PMMA) from wind blade waste.
  • To evaluate the potential of recycling technologies in supporting a circular economy for wind energy.
  • To compare the environmental footprint of recycled materials versus virgin counterparts.

Main Methods:

  • Lifecycle assessment (LCA) was employed to evaluate environmental impacts.
  • Thermolysis recycling of thermoplastic-based blade waste was analyzed, including monomer recovery.
  • Recycled glass fibre production via cleaning and remelting of recyclates was assessed.

Main Results:

  • Recycled thermoplastic and glass fibre products show reduced environmental impacts compared to virgin materials.
  • Material production global warming potential decreased by up to 54% for recycled thermoplastic and 26% for recycled glass fibre.
  • Wind blades using recycled materials are projected to have a 27% lower cradle-to-grave global warming potential.

Conclusions:

  • Recycling composite wind blade waste offers significant environmental benefits, including reduced global warming potential.
  • The developed material and recycling solutions facilitate the decarbonization of wind energy production.
  • These advancements are critical for establishing a circular economy within the wind blade industry.
