Types of Wind Turbines
Wind turbines come in several types, each designed to harness wind energy efficiently in different environments and applications. The most common are horizontal-axis wind turbines (HAWT), which dominate wind farms around the world due to their high efficiency and proven reliability. These turbines are easily recognizable by their large rotor blades and tall towers, and are typically used in utility-scale wind farms to generate significant amounts of electricity.
Vertical axis wind turbines (VAWT), while less common, offer unique advantages such as reduced noise and lower visual impact, making them suitable for urban and residential settings. Wind turbines in urban environments can handle turbulent and changing wind patterns caused by buildings. The choice between HAWT and VAWT depends on factors like wind speed, site conditions, and the intended application. Darrieus turbines are more efficient than Savonius types but may require an external starting mechanism. Savonius turbines, on the other hand, are less efficient but are simple, inexpensive, and can start from any wind speed. HAWTs are common for large-scale power generation, whereas VAWTs are often suited for urban settings due to their omnidirectional nature.
Utility-scale wind turbines are specifically designed to deliver large-scale power generation, supporting the needs of the grid and enabling the development of extensive wind farms. Utility-scale wind Farms power the electrical grid for large populations. Meanwhile, smaller wind turbines are used for localized applications, such as residential or commercial electricity generation. The ongoing development of new wind turbine technologies—including floating turbines and those built with advanced materials—continues to expand the range of suitable applications for wind energy, ensuring that turbines can be designed to meet the unique needs of different industries and environments.
Offshore Wind Turbines
Offshore wind turbines are playing an increasingly important role in the wind energy industry, offering access to stronger and more consistent winds than many onshore locations. These turbines are installed in marine environments, often far from shore, and require specialized equipment and techniques for installation, such as large ships and cranes. Offshore installations of wind turbines are ideal for consistent, strong winds in large bodies of water. Offshore wind turbines are engineered to withstand harsh marine conditions, including saltwater corrosion and powerful storms.
The development of offshore wind farms is accelerating in regions like Europe, Asia, and North America, where space for onshore wind farms may be limited. Offshore wind turbines offer several advantages, including reduced visual and noise impact, as well as higher energy production due to the favorable wind conditions at sea. However, they also present unique challenges, such as higher installation and maintenance costs and the need for robust infrastructure.
To address these challenges, companies like Retek Industrial Co.,Limited and ABB are developing advanced power converters, control systems, and other solutions specifically designed for offshore applications. These technologies support the reliable operation of offshore wind turbines, helping to unlock new opportunities for wind energy and drive the global transition to renewable power.
Introduction to Wind Converters
Wind converters play an important role in the generation of electrical power from wind energy. The controller within a wind converter manages the conversion process, ensuring efficient operation and communication with other system components. These devices are essential components in wind turbines, converting the mechanical energy produced by the rotor blades into electricity that can be fed into the power grid. Wind turbine blades create a difference in air pressure that generates lift and causes the blades and connected shaft to spin.
Electrical subsystems in large-scale turbines can achieve an efficiency of 93% to 98%. Wind power converters are mainly used together with generators to optimize energy production. Wind converters are primarily categorized as horizontal-axis (HAWT) and vertical-axis (VAWT) types. Partial-Scale Converters (PSFC) connect only the rotor to the grid through the converter, reducing costs but limiting output.
As wind power continues to grow as a sustainable energy source worldwide, the development and deployment of advanced wind power converters have become crucial to meet the increasing demand for reliable and efficient energy solutions.
The Role of Wind Converters in Wind Turbines
In a wind turbine system, the converter serves as the interface between the generator and the grid. It converts the variable frequency and voltage generated by the turbine’s rotor into stable electrical power compatible with the grid’s requirements, regulating the output from the stator to control voltage amplitude, frequency, and phase for optimal grid integration. This conversion process ensures that the electricity produced can be reliably integrated into the power grid, regardless of fluctuations in wind speed or turbine operation. Wind converters help achieve Variable Speed Constant Frequency (VSCF) for better power generation efficiency. The flexibility offered by wind converters allows wind turbines, including larger wind turbines and offshore wind turbines, to operate efficiently in a variety of conditions.
Types of Wind Power Converters and Their Applications
Wind power converters vary in design depending on the type and scale of the wind turbine system. Utility-scale wind turbines, which constitute the majority of installed wind farms, typically use sophisticated power converters designed to handle high power levels and harsh environments. These converters are built with robust hardware and advanced software solutions to ensure continuous operation and minimize failure events.
ABB offers wind turbine converters for utility-scale wind turbines. ABB’s MV wind converters are designed for utility-scale wind turbines and will have ratings of up to 20 MW and beyond. Full-Scale Converters (FSFC) connect both the stator and rotor through the converter, providing greater control and flexibility. Wind converters are designed to fulfill strict grid codes and can be air-cooled or air/water-cooled for harsh environments.
To address the diverse requirements of different wind energy applications, manufacturers offer a comprehensive portfolio of wind power converters, featuring a range of high-power, high-efficiency components tailored for both onshore and offshore systems.
For offshore wind turbines, which face more demanding conditions due to their location, converters are designed to be compact and flexible, providing reliable performance while reducing maintenance needs. The higher voltage level of medium voltage converters results in lower currents in the electrical drivetrain. Medium voltage converters enable a higher penetration of renewable energy into the grid without compromising stability.
The new generation of medium voltage converters has built-in intelligent software and digital features for remote monitoring and diagnostics. These converters can deliver an estimated 33% uplift in power with the same number of components as their lower power predecessors. The combination of converter technology and turbine design enables these systems to deliver optimal power output and durability.
