摘要： Device and method for disconnecting and reconnecting an inverter initially connected to the electrical network and working as a current source (CSC) comprising the steps of continuously monitoring the instantaneous voltage and frequency of the electrical network until detecting that one of said parameters is outside normal predetermined ranges; disconnecting the inverter from the electrical network and maintaining the inverter voltage at the nominal voltage and frequency of the electrical network; continuously monitoring the instantaneous voltage and frequency of the network until detecting that their parameters are stable within said normal predetermined ranges; and reconnecting the inverter to the electrical network. The method further comprises steps for switching the inverter so that it works as a voltage source (VSC), setting the inverter voltage at the nominal voltage and frequency of the electrical network; and fixing the inverter output angle according to an internal clock having a frequency equal to the nominal frequency of the electrical network.
