Abstract: The invention relates to sheath for a blade that has a uniform assembly direction over the radial height of the sheath whether the blade has a straight or curved trajectory. This is achieved by the a sheath formed around the edge, having a first inner surface wherein a first tangential vector projected tangentially to the first inner surface in a direction away from the head portion in an longitudinal plain forms a first angle with the rotational axis that does not vary over the radial height of the sheath while a second tangential vector projected tangentially from any point of the second inner surface of the sheath in a direction towards the head portion intersects the first tangential vector.

Abstract: A voltage source converter includes a converter limb having limb portions separated by an AC terminal and extending between DC terminals, each limb portion including a primary switching element to switch the limb portion into and out of circuit. The converter further includes an auxiliary limb. The primary switching element of each limb portion is switchable to switch the auxiliary limb into and out of circuit with the corresponding limb portion. The converter further includes a control unit to, in one mode, inject a circulation current that flows in one direction in one of the limb portions and minimize a current flowing in the opposite direction in that limb portion. Each primary switching element switches the respective limb portion into or out of circuit following the minimization of the limb portion current by the circulation current.

Abstract: The invention relates to a method for controlling a gas turbine, operating with an integral fuel reactivity measurement concept. In order to fast determine a safe operation range of the gas turbine with respect to flashback and blow-out, the method includes deducing the fuel composition and therefore the fuel reactivity by combined measurements of (n−1) physico-chemical properties of a fuel mixture with n>1 fuel components, for deriving the concentration of one component for each physico-chemical property of the fuel gas mixture or for determining of a ratio of the fuels with known compositions and adjusting at least one operation parameter of the gas turbine at least partially based on the determined property of the fuel gas mixture entering the combustors. With the technical solution of the present invention, by way of detecting fast changes in fuel gas, it is assured that the gas turbine may operate with varieties of fuel gas under optimized performance and in safe operation ranges. In actual applications, the present invention may improve flexibility of gas turbines and cost effectiveness of operation of the gas turbines.
