Abstract: The presented report describes investigations on the operating and control behaviour of closed-cycle HU-Helium turbine plants. The aim of these investigations is to prove that the requirements of the grid can be met by the power plant without undue operating conditions. This study refers to a non-integrated and an integrated design of a singleeshafteplant . For comparison the behaviour of anadequate split-shaft-arrangement is opposed. Essentialiy the following control modes are regarded: - Gas injection and discharge at various points of the circuit, - opening and closing of by-passes, control of losseofeload from Full Ioad with the aid of by-passes. The gas injection and discharge gives relatively slow power changes bot favourable efficiencies at part-load . With gas injection on the HP side the power output rises faster than would correspond with the increase of inventory . This behaviour can be used advantageously for frequency maintenance. The by-pass control is characterized by rapid power changes in connection with unfavourable part-load efficiencies. The associated pressure-gradients are inside of tolerable limits. The loss-of-load from fall load as most extremely operating case can be met by by-pass control with PI-controller in the single-shaft-plant. All together one can establish that the single-shaft-plant can fulfil all investigated operating requirements without undue operating conditions. But these cannot be excluded in some cases with the split-shaft-arrangement.
