The voltage drop across the capacitor, (direct axis, vCd and quadrature axis, vCq ), is included in the matrix in the expression 1/pC. The transformer ratio from the stator to the rotor is assumed to be unity and transformations should be introduced in the rotor parameters when there is need to refer them to the stator. 3 Stator direct axis component with an RL load. rotor. So, the d–q coupled voltage drops are due to the relative position of the coils as well as the current variation through them.
The stator voltage E1 is leading Vph . In the induction generator, the magnetizing current produces the magnetizing field B. For this, synchronous generators or other electrical sources are used to feed external circuits in association with induction generators. Some interesting conclusions can be drawn from the observations above. As the current Im reaches values around 20 to 40% of Ir and supplies the generator at the circuit voltage, the excitation power (in kVA) will also reach 20 to 40% of the generator’s rated values.
