Wind power

How is a wind turbine built?

How is one made wind turbine? What are its components? What is the technology needed to design a efficient wind system? Since we often talk about it, it is worth investigating the topic by delving into (without exaggerating) the technical details of the matter. The result will be the awareness that behind the innovation there is, as always, a long research and development work.

A wind turbine consists of all the components necessary for the electro-mechanical conversion of energy. The turbine blades, generator, and electrical converter are the three main components of a wind power generator. The most important component among the interacting elements of a wind turbine it is the generator that creates the electricity.

The generator output powers the subsystem consisting of the converter, which regulates the transferred electrical power. The power is then transferred to the grid. Some of the electrical components used in this regulation and energy transfer process include transformers, capacitors, inductors and power electronics, as well as cables and bus bars.

The engineers who design the wind turbines they face a major challenge: to accurately determine the specifications of multiple individual components - which often come from different manufacturers - and then connect them into an efficient system.

Also for this reason, without the use of software simulation tools it is almost impossible to determine the performance of a complex heterogeneous system, such as a wind turbine, which incorporates high performance requirements necessary for the electrical system.

A reference example for the design of all sections of a wind generator, so as to arrive at an efficiently designed and optimized system as a whole, is the software ANSYS Simplorer.

Thanks to this technology, the engineer can build a complex system entirely using analytical models. With the help of detailed models of the finite element method (FEM) and other simulation tools, users have the ability to analyze, optimize and integrate all components of the complex end-to-end system.

These components include the design of the network coupling and the integration of power control based on existing characteristics of the electric generator, as well as permissible power fluctuations and / or the suppression of harmonics.

The use of simulation tools can also be useful for testing critical conditions such as a short circuit which could occur in the vicinity (or at a specific distance) of the generator, the thermal loads supported, or the design of networks to protect against other effects, such as electrical discharges.
