Method and circuit for testing a power producer or a power consumer which can be connected to a power grid

摘要

Described is a method for testing a power producer or a power consumer that can be connected to a power grid. The power producer or the power consumer is connected to a terminal point. A converter circuit is provided for influencing a voltage that is present at the terminal point. The converter circuit is connected via a transformer to the terminal point. In at least one embodiment, a series connection is configured with a choking coil and a first switch and connected to the terminal point. In a time coordinated manner, the first switch is initially closed and the converter circuit is influenced such that the voltage has the desired value at the terminal point, whereupon the second switch is then opened.

1. A method for a power producer or a power consumer which is connectable to a power grid, the method comprising:
connecting the power producer or the power consumer with a converter circuit via a transformer at a terminal point; connecting a first switch and a choking coil in a series connection with the terminal point; in a time-coordinated manner, closing the first switch and influencing the converter circuit to adjust voltage at the terminal point to a desired value; and subsequently opening the first switch for simulation of a voltage overload on the power grid.
