In addition to achieving further increases in efficiency while simultaneously optimising costs, the turbines must be designed for higher load cycles and load cycle speeds in order to be able to compensate for the fluctuations caused by the fluctuating feed-in of wind and solar power. Particular importance is attached to the problem of optimising the integration of turbomachinery into the power generation environment, which is increasingly characterised by renewable energy converters, through new developments. This requires an increase in the cyclical operation of the turbines and operation at very low partial loads. Due to the unfavourable inflow conditions and the increase in detached areas, a higher vibration excitation of the blades occurs, which must be counteracted by suitable design measures. In addition to the development of new systems, efforts to retrofit existing systems also represent important challenges for manufacturers and operators. The latter involves not only a radical increase in the number of starts, but also more efficient operation of the turbines in the lower load range and with larger load gradients, for which the energy systems must be upgraded in terms of robustness and longer maintenance intervals.
