O principal objetivo desta dissertação é desenvolver uma metodologia que permita
avaliar um modelo de um determinado gerador eólico, seus componentes, características
e dinâmica de operação nas componentes de controlo de tensão e controlo de
frequência.
A metodologia de testes realizados teve como base os testes de conformidade de um
operador de rede de transporte e do CEI (Comité Eletrotécnico Internacional) adaptada
a este contexto.
Nesses testes, não só a capacidade de continuar conectado à rede elétrica na presença
de cavas de tensão -Fault Ride Through, mas também a capacidade de resposta a
variações de frequência -Frequency Sensitive Mode- foram as principais características
analisadas, sendo estas propriedades reconhecidas como fundamentais no perfil de um
aerogerador para a sua contribuição para a segurança e estabilidade da rede elétrica.
Com base nos resultados alcançados, é realizada uma apreciação do desempenho
esperado do aerogerador com base nos requisitos estipulados pela legislação
Portuguesa, Portaria nº73/2020, e é concluído se o mesmo se encontra conforme os
parâmetros exigidos.
Da análise dos resultados foi possível testar a conformidade dos modelos dos
aerogeradores testados quando comparados com os requisitos definidos pelo código de
rede.
The main goal of this dissertation is the development of a methodology that allows to evaluate a model of a determined wind generator, their components, characteristics and dynamics of operation in relation to different types of control. These are grouped in voltage control and frequency control. The testing methodology developed was based on the conformity tests carried out by a transport system operator and IEC (International Electrotechnical Committee). In those tests not only the capacity of being connected to the grid during a voltage droop -Fault Ride Through (FRT)- but also the activation of the frequency sensitive mode (generator response to system frequency deviations) are the main characteristics analyzed, being these fundamental properties in the profile of a wind turbine for the contribution of safety and stability of the electric grid. Based on the results achieved, a performance assessment of the wind turbine is carried out based on the requirements stipulated by Portuguese legislation, Portaria No. 73/2020, and it is concluded whether it meets the required parameters. From the analysis of the results, it was possible to confirm whether the models tested were within the requirements defined by the network code.
