Estudio del entrehierro en generadores síncronos de turbinas eólicas Siemens Gamesa
Abstract
La energía eólica es junto a la solar la fuente de energía renovable más prometedora para los próximos años. La tecnología de tipo offshore permite la generación de mayor energía al estar situadas en el mar, donde los vientos son mayores. Además, esta tecnología es más reciente que la onshore y se encuentra en plena fase de expansión.
En este proyecto se desarrolla un estudio acerca de la optimización del entrehierro del tipo de turbina offshore DD8 de la compañía Siemens Gamesa. Se tendrán en cuenta aspectos mecánicos como tolerancias de las distintas partes que influyen en el entrehierro, así como aspectos eléctricos que permitirán el cálculo de la energía total producida en función del entrehierro. Además, se realiza un análisis económico para Borssele, el primer parque eólico en el que este tipo de turbina se implementa.
Por último, se incluye una comparación del entrehierro conseguido tras la optimización y el que actualmente se utiliza en Siemens Gamesa, así como las futuras líneas de mejora que permitirían mejorar aún más el rendimiento de este tipo de turbina gracias a una mayor optimización del entrehierro.
Wind Energy is together with solar, the most promising source of energy for the coming years. Offshore technology allows the generation of a bigger amount of Energy since the turbines is placed in the sea, where the wind speed is higher. Moreover, this technology is more recent than onshore and it is now at the expansion phase. In this project, a study about air gap optimization of the offshore turbine type DD8 of the Siemens Gamesa Renewable Energy company is developed. Mechanical aspects will be taken into account such as tolerances of the different parts that influence the air gap as well as electrical aspects that will allow the calculation of the total energy produced as a function of the air gap. Moreover, an economic study for the first offshore windfarm which uses this turbine, Borssele, is carried out. In addition, the project includes a comparison of the air gap achieved after the optimization and the one currently used in Siemens Gamesa, as well as the future lines of improvement that would allow improving even more the performance of this type of turbine thanks to a greater optimization of the air gap.
