A crescente mobilidade levou diretamente à deterioração das condições de tráfego, ao consumo extra de combustível, ao aumento das emissões de gases de escape dos automóveis, à poluição do ar e à redução da qualidade de vida. Além de ser um modo de transporte limpo, barato e ótimo para viagens de curta distância, o ciclismo pode oferecer soluções para o problema da mobilidade urbana. O sistema de partilha de bicicletas elétricas é considerado como uma implementação de tecnologia limpa, uma vez que tem a possibilidade de utilizar a energia solar fotovoltaica, sendo esta, a chave de desenvolvimento deste sistema.
Com a introdução das bicicletas elétricas na mobilidade nacional e, consequentemente, a necessidade de carregamento da bateria regularmente, é de esperar que estas possam estimular algum impacto nas redes elétricas. Por esta razão, o presente trabalho visa analisar o possível impacto que este meio de transporte pode causar na qualidade de energia elétrica distribuída. O estudo foi conduzido por meio de método analítico, que inclui a análise dos ensaios de carregamento. Para tal, recorreu-se aos ensaios feitos no posto de carregamento rápido de veículo elétrico localizado na FCS, de forma a obter uma análise do impacto desta tecnologia na rede de distribuição elétrica. Para os dados recolhidos (tensão, corrente, potência ativa, potência reativa, conteúdo harmónico e equilíbrio de fases), foram apenas analisados os valores médios de cada grandeza, com exceção do conteúdo harmónico em cada ordem, para os quais foram analisados os valores máximos. O registo dos dados foi feito de forma contínua durante todo o intervalo de carregamento, com períodos de amostragem de 1 segundo.
The increased mobility has led directly to deteriorating traffic conditions, extra fuel consumption, increased exhaust emissions from cars, air pollution and reduced quality of life. In addition to being a clean, cheap and great mode of transport for short trips, cycling can offer solutions to the problem of urban mobility. The system of sharing electric bicycles is considered as an implementation of clean technology, since it has the possibility of using photovoltaic solar energy, which is the key to the development of this system. With the introduction of electric bicycles into national mobility and, consequently, the need to charge the battery regularly, it is to be expected that they may stimulate some impact in the electric networks. For this reason, the present work aims to analyze the possible impact that this means of transport can cause in the quality of distributed electric energy. The study was conducted using an analytical method, which included analysis of the loading assays. For this, we used the tests carried out at the electric vehicle rapid charging station located at FCS, in order to obtain an analysis of the impact of this technology on the electric distribution network. For the collected data (voltage, current, active power, reactive power, harmonic content and phase equilibrium), only the average values of each magnitude were analyzed, except for the harmonic content in each order, for which the maximum values were analyzed. The data was recorded continuously throughout the loading interval, with a sampling periods of 1 second.
