Abstract
método e dispositivo para comutação segura de um sistema fotovoltaíco após diferenciação do tipo de arco. a invenção refere-se a um método e um dispositivo para a comutação segura de um sistema de tensão contínua (1), em particular de um sistema fotovoltáico, na eventualidade de se verificar um arco elétrico no lado da tensão contínua, em que a corrente contínua gerada e a tensão contínua produzida são estabelecidas em relação ao controlo da potência. na eventualidade de deteção de um arco elétrico pelos sensores, o ajustamento da potência (mpp) é modificado e a modificação da potência do arco é detetada, pelo que, na eventualidade de uma redução da potência do arco elétrico, é identificado um arco elétrico em série ou em pararelo, de acordo com a direção da modificação (<30>p ~u0~, <30>p ~ik~) do ajustamento da potência (mpp). na eventualidade de um arco elétrico em série é produzida uma interrupção da corrente contínua e na eventualidade de um arco elétrico em paralelo é produzida uma corrente de curto-circuito.
