Germany:
Study on the Reactive Power Compensation for the 380 kV Grid Connection of the CCPP "Niehl 3"

The grid connection of the new Niehl 3 CCPP is designed as a so-called hybrid grid connection, i.e. with a connection to both the 380 kV grid and the 110 kV grid. An important aspect here is the reactive power characteristic. In particular, the 380 kV cable between the "Niehl Hafen" and "Opladen" substations with its large capacitive component can lead to unwanted voltage increases during off-peak periods.
