The more renewable energies flow through our grids, the stronger the power fluctuations become - also due to weather conditions. To compensate for overloads on the one hand and bottlenecks on the other, expensive redispatch measures are usually necessary. Phase-shifting transformers (PSTs) enable distribution system operators like Tennet to control load flows, save costs, and keep grids stable despite volatile generators: They shift the overload from one power line to others in such a way that the grid as a whole is better utilized. Four new PSTs with on-load tap-changers from MR now ensure this at the Würgau substation. In the video, this project is discussed by Dr. Florian Martin, Head of Asset Technology at TenneT, and Wilfried Breuer, Managing Director of MR.
940 tons of power regulation
To ensure that volatile load flows from renewable energies are optimally distributed in the grid, TenneT's Würgau substation now has four new phase shifters - with on-load tap-changers from MR.

In the future, customers can also rely on MR's latest development: The new VACUTAP® VRL® switches up to ten MVA and is virtually maintenance-free. It is also a world record holder: to save space, MR has designed the output to an incredible 3,200 amperes. That's more than twice as much as the largest tap changer has ever had. MR Managing Director Wilfried Breuer: "Its extraordinary switching capacities, even at very high phase currents, make it possible to dispense with symmetrical current splitting in the control winding. This reduces material usage, construction volume, weight and also the operating losses of the transformer."
