Working Student Method Development Harmonic Load Flow Calculation (m/w/d)

Amprion connects. Our transmission network transports electricity for 29 million people in an area from the North Sea to the Alps. A third of the German economic output is generated there. Our lines are lifelines of society. We keep our net stable and safe - and prepare the way for the energy transition: We build our network and work on new ideas for a climate-friendly, safe and efficient energy system.

DISCLOSURE: In the electrical power transmission network, it is necessary for the stable operation of the planned power-electronic HGÜ and Statcom systems to monitor the harmonic voltages and currents in the network in order to identify short-term unfavourable sources and initiate countermeasures. By accepting a limited amount of measuring instruments and a limited measurement accuracy, methods based on our geometric and distributed network models are to be tested and re-edited if necessary. This work focuses on the development of methods and scripts. The test is carried out on the basis of measurement data, which we receive from measuring points specially constructed before this purpose. These measuring points are GPS-synchronized, so that every 3 seconds we get a snapshot of the network up to the 50th harmonic vibration, so that we can then try to reckon the harmonic load flow via the above-mentioned network model. The following questions must be answered: Is the measurement uncertainty sufficiently small? Is the model quality sufficiently good and where and how many measuring points should we optimally place in order to be able to calculate the harmonic load flow sufficiently well in the entire network area? In a second step, it is necessary to clarify with which mathematical approaches one can identify and locate the sources for disturbances on the basis of the harmonic load flow.
