When the stator and rotor windings of a conventional three-phase wound-rotor induc- tion machine are connected in series but with opposite phase sequence, a series-connected induction machine is created. In order for this machine to become self-excited, the machine terminals must be connected in parallel with a three-phase capacitor bank. In this thesis, d-q theory and space vectors are applied to investigate the performance of a series-connected induction machine operating as a standalone generator, for example in a wind turbine application. Accurate and complete models of the generator at no-load and with resistive and resistive-inductive loads are derived. The minimum capacitance for self-excitation at constant speed is also obtained at no-load and when the generator is loaded. Numerical simulations predict the generator output voltage and power output during steady-state operation.
