  • Feasibility of monitoring large wind turbines using ...

    2010-12-1 · Within the scope of the work, the 3D dynamic response of the rotor is captured at 33 different locations simultaneously by using 4 CCD (charge coupled device) cameras while the turbine is rotating. Initial results show that the deformations on the turbine can be measured with an average accuracy of ±25 mm from a measurement distance of 220 m.

  • Steam turbine upgrades for power plant life management

    2011-1-1 · For a ‘3+1’ with three control valves open feeding three-quarters of the arc and one control valve closed, depending on the heat drop of the first stage, the turbine will typically swallow in the region of 90 % of the full capacity for all valves wide open. Additional control for further reduction in mass flow is then delivered by throttling the remaining valves together.

  • Rotor Blade - an overview | ScienceDirect Topics

    7. The rotor blades of an axial-flow turbine stage are 100 mm long and are designed to receive gas at an incidence of 3 deg from a nozzle row. A free-vortex whirl distribution is to be maintained between nozzle exit and rotor entry. At rotor exit the absolute velocity is 150 m/s in the axial direction at all radii.

    Two designs of rotor models are proposed and their performance is analyzed. The first one is a classical rotor with non-linear chord and twist distributions and the second one is a new linearized rotor design. Analytical optimizations of the linearized blades are employed through three tuning steps using Blade Element Momentum (BEM) theory.
