A balanced three-phase, negative sequence, Y-connected generator is connected to a three-phase balanced Y-connected load. The generator has an impedance of 1.5-j1.25 Ω/phase. The impedance of the line connecting the generator to the load is 2.5+j1.25 Ω/phase. The phase “B” load voltage is 15∠20 kV. The impedance of each phase of the Y-connected load is 60-j80 Ω/phase. Calculate line voltage VABVAB at the load.
Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
