    reactive power with the grid. Running on different operating conditions‚ the rotor of DFIG has different energy flow directions. Although energy always flows from stator to grid‚ sub-synchronous operating state‚ the energy flows from the grid to the rotor; super-synchronous operating state‚ the energy flows in an opposite way. Therefore‚ in order to make the system run in a wide speed range‚ it has to ensure that the rotor energy can flow in double-way. This process is achieved with GSC by regulating

    DESIGN OF TESLA TURBINE Abstract:- The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. The Tesla turbine is also known as the boundary layer turbine‚ cohesion-type turbine‚ and Prandtl layer turbine (after Ludwig Prandtl). Bioengineering researchers have referred

    control systems‚ robotics‚ mecatronics‚ electric vehicles‚ high speed transportation etc. SYNCHRONOUS RELUCTANCE MOTORS * A reluctance motor is a type of synchronous electric motor which induces non-permanent magnetic poles on the ferromagnetic rotor. * Torque is generated through the phenomenon of magnetic reluctance. Operating principle * Whenever a piece of ferromagnetic material is located in a magnetic field a force is exerted upon the material tending to bring it

    be familiar with some of the terminology associated with it. The rotor is the spinning component that has wheels and blades attached to it. The blade is the component that extracts energy from the steam. There are two basic types of turbine designs. One is called the "impulse" design in which the rotor turns due to the force of steam on the blades. The other is called a "reaction" design‚ and it works on the principle that the rotor derives its rotational force from the steam as it leaves the blades

    corresponds to a physical position of the rotor. The frequency is exactly determined by the formula f = RPM x p / 120 where f is the frequency (Hz)‚ RPM is the rotor speed (revolutions per minute) and p is the number of poles formed by the stator windings. A synchronous generator is essentially the same machine as a synchronous motor. The magnetic field of the rotor is supplied by direct current or permanent

    with fuel and ignited by the ignition system. The combustion is a constant process that heats and expands the released gases before they reach the two-stage axial turbine. The gases clash on the turbine blades‚ which causes a rotation of the common rotor shaft. After the gases leave the turbines they flow into the APU exhaust and are released in the open

In a right turn‚ the blue portion will have rolled to the left. The rotor‚ mounted in a sealed housing‚ spins in a horizontal plane about the vertical axis. The housing pivots about the lateral axis on a gimbal‚ which in turn is free to pivot about the longitudinal axis. The instrument case is the third gimbal necessary
