Abstract(s)
Com a crescente incerteza à volta dos mercados de energia e a
necessidade de descarbonização das sociedades, a procura por parte
das empresas de independência energética tem vindo a crescer. Assim,
a quantidade de sistemas fotovoltaicos aumentou exponencialmente e
como tal, o portefólio de ativos fotovoltaicos tem acompanhado este
aumento, criando a necessidade de melhorar e otimizar os processos de
gestão dos mesmos. Nesta ótica o tema da alarmística dos inversores,
que detetam e indicam problemas relacionados com a instalação
fotovoltaica, ganha relevância. Este trabalho, realizado no âmbito de
estágio curricular na EDP Comercial, teve como objetivo principal a
elaboração de procedimentos relacionados com a alarmística dos
inversores. Analisaram-se as problemáticas, as suas causas e avaliou-se
os seus efeitos, criando-se procedimentos de resolução, bem como o
estabelecimento de thresholds de intervenção para a alarmística, que
variam consoante a gravidade do problema e o estado do inversor. Na
criação dos procedimentos de resolução, dividiram-se as ações em
Remote Service- ações de resolução feitas remotamente e Field Service
- ações no terreno. Com o trabalho realizado conclui-se que a qualidade
técnica da execução por parte dos instaladores e a qualidade dos
materiais têm uma correlação direta na frequência da alarmística.
Assegurar estas premissas para além de reduzir a quantidade de alarmes
da instalação, também torna a instalação mais segura e vantajosa
economicamente.
With the growing uncertainty surrounding the energy markets and the need to decarbonize societies, companies demand for energy independence has been growing. As a result, the number of photovoltaic systems has increased exponentially and, as such, the portfolio of photovoltaic assets has kept pace with this increase, creating the need to improve and optimize their management processes. The topic of inverter alarming, which detects and indicates problems related to the photovoltaic installation, is gaining relevance. This work, carried out as part of a curricular internship at EDP Comercial, had its main objective the development of procedures related to inverter alarming. Problems were analyzed, their causes and effects assessed, creating resolution procedures, and establishing intervention thresholds for alarming. These vary according to the severity of the problem and the state of the inverter. In the creation of the resolution procedures, the actions were divided into Remote Service - resolution actions carried out remotely and Field Service - actions in the field. This work led to the conclusion that the technical quality of the installers' work and the quality of the materials have a direct correlation with the frequency of alarms. Ensuring these premises not only reduces the number of alarms in the installation, but also makes the installation safer and more economically advantageous.
