Abstract
The invention relates to a method for transferring, during a predetermined transfer duration, the electric power supply of an electric distribution line (7) from a first source (1) to a second source (2), without overlapping of the two sources. The invention also relates to a source inverter implementing such a method.
Claims16
A method for transferring, during a predetermined transfer duration, the electric power supply of an electric distribution line from a first source to a second source, without overlapping of the two sources, a first switch, which is connected, on the one hand, to the first source and, on the other hand, to the distribution line, being commanded to close or open in order to connect or disconnect the first source to/from the distribution line, a second switch, which is connected, on the one hand, to the second source and, on the other hand, to the distribution line, being commanded to close or open in order to connect or disconnect the second source to/from said distribution line,
- which method is characterized in that:
- either a first delay time is applied before a command for opening the first switch (4);
- or a second delay time is applied before a command for closing the second switch;
- the first delay time or the second delay time being computed so that the time interval between a disconnection of the first source and a connection of the second source is equal to the transfer duration.
