Decentralized power generation: New Megawatt testing equipment for over-voltage ride through

To keep pace with the latest changes to grid codes and testing standards the facilities of Fraunhofer IEE‘s laboratory SysTec have recently been upgraded by an over-voltage-ride-through (OVRT) test container. The new testing equipment is designed to analyze the dynamic behavior of wind turbines, photovoltaic inverters and combined heat and power units during short time over voltages of the supply voltage. Since the revision of grid codes in fall 2018 riding through short-term voltage swells now also became a requirement for generating plants installed in regional and local distribution grids.
