Heinrich-Mandel Prize 2010

The Board of Trustees of the VGB-FORSCHUNGSSTIFTUNG awarded the Heinrich-Mandel Prize 2010 to

  • Florian Mura, E.ON Energy Research Center, Aachen, for the analysis of a gas turbine system, which can be operated at optimized speed disregard of the load conditions set by the net frequency.

The 10,000 Euro prize was handed over by the VGB chairman on the occasion of the VGB Congress "Power Plants 2010" on 22nd September 2010 in Essen.

Florian Mura (31) analysed within the framework of the project "Medium-Voltage Variable-Speed Mini-Turbine" a gas turbine system, which can be operated at optimized speed disregard of the load conditions set by the net frequency. Similar to wind power plants, this is realised using a power electronic converter, uncoupling the speed of the mechanical shaft from the net frequency.

Numerical simulation demonstrated that this operation mode improves significantly the thermal efficiency of the gas turbine. Compared to conventional constant speed system the efficiency in part load operation is higher by several percentage points.

This efficiency increase is advantageous especially when gas turbines are operated in partial load in order to compensate fluctuating power of renewable energies. Variable speed gas turbines achieve a significant reduction of fuel costs.
