Retrofitting of the Uk3 generator transformer in the Cologne substation Deutsche Bahn operates frequency-elastic network coupling converters or traction current converters in several central converter plants, which supply the public three-phase 50 Hz power network Connect the general national supply to the single-phase 16.7 Hz traction power network. The frequency-elastic network coupling converters mainly consist of two rotating electrical machines that are rigidly coupled to one another - a double-fed one Three-phase asynchronous motor (50Hz) with a GTO power control and a single-phase synchronous generator with DC excitation. The power from the public 50Hz three-phase network is transferred to the 110kV using a 50Hz three-phase transformer Operating voltage/machine voltage (here 10.5kV) of the asynchronous machine is reduced and increased to 110kV by a single-phase 16.7Hz single-phase transformer. As part of the planned substation renovation (16.7 Hz) in the Cologne converter plant, the transformer is to be installed Uk3 (16.7Hz, 33.3 MVA, ABB) will be transported away and subjected to an external factory inspection.
