What is a Vertical Axis Wind Turbine (VAWT)? A Vertical Axis Wind Turbine (VAWT) is a type of wind turbine where the main rotor shaft is set vertically. This design is in contrast to the more common Horizontal Axis Wind Turbines (HAWT), where the rotor shaft is set horizontally. VAWTs have blades that rotate around … Read more
I. What is Cut-in Wind Speed? Cut-in wind speed refers to the minimum wind speed at which a wind turbine begins to generate electricity. It is the threshold at which the turbine’s blades start to rotate and produce power. Below this speed, the turbine remains idle, unable to harness the kinetic energy of the wind. … Read more
I. What is a Feed-in Tariff? A Feed-in Tariff (FIT) is a policy mechanism designed to promote the adoption of renewable energy sources by providing financial incentives to individuals or businesses that generate electricity from renewable sources such as wind, solar, or biomass. The concept of a FIT is based on the idea that by … Read more
I. What is Aerodynamic Braking? Aerodynamic braking is a method used to slow down or stop moving objects by utilizing air resistance. This technique is commonly used in various industries, including automotive, aerospace, and wind energy. In the context of wind energy, aerodynamic braking is employed in wind turbines to regulate the speed of the … Read more
I. What is a Synchronous Generator? A synchronous generator is a type of electrical generator that produces alternating current (AC) by converting mechanical energy into electrical energy. It operates on the principle of electromagnetic induction, where a rotating magnetic field induces a current in the stator windings. Synchronous generators are commonly used in power plants, … Read more
I. What is Flapwise Bending? Flapwise bending is a phenomenon that occurs in wind turbine blades, where the blade bends along its length in the direction of the wind flow. This type of bending is caused by the aerodynamic forces acting on the blade as it rotates, creating a bending moment that causes the blade … Read more
I. What is Voltage Control? Voltage control is the process of regulating the voltage levels within an electrical system to ensure that they remain within acceptable limits. In the context of wind energy systems, voltage control is crucial for maintaining the stability and reliability of the grid. Voltage control is necessary because fluctuations in voltage … Read more
I. What is the Operational Envelope in Wind Energy? The operational envelope in wind energy refers to the range of conditions under which a wind turbine can safely and efficiently operate. This includes factors such as wind speed, temperature, humidity, and other environmental variables that can impact the performance of the turbine. Understanding the operational … Read more
I. What is a Permanent Magnet Generator? A permanent magnet generator is a type of electrical generator that produces electricity using permanent magnets rather than electromagnets. This means that the generator does not require an external power source to create a magnetic field, making it more efficient and reliable than traditional generators. Permanent magnet generators … Read more
I. What is Wind Energy Consulting? Wind energy consulting involves providing expert advice and guidance to companies and organizations involved in the development, implementation, and management of wind energy projects. These consultants are highly knowledgeable in the field of renewable energy and specialize in helping clients navigate the complex and ever-changing landscape of wind energy … Read more
