“…Various analyses are performed on steadystate, transient, and dynamic performances under stable/ unstable conditions [16,17]. When an induction motor is operated as an autonomous generator, although the rotational speed is kept at a constant value, the loads connected to the generator affect both voltage and frequency [18]. Therefore, the induction generator should maintain a continuous terminal voltage under varying loads.…”

Asynchronous or induction machines are among the leading devices in the electrical industry. They are well suited for motor and production applications with power ratings from a few kilowatts to megawatts. In addition, their use in renewable energy systems, especially in wind conversion systems, is increasing daily due to their advantages, such as low cost, brushless, and robust structure. In this work, the operation of a three-phase asynchronous motor with a winding rotor as an alternator, the variation of the voltage produced depending on the excitation current by keeping the number of revolutions constant, and the interpretation of the voltage produced according to the number of revolutions by keeping the excitation current constant have been investigated. The variation of the terminal voltage in ohmic, inductive, and capacitive loads has been experimentally investigated by observing the source voltage providing the rotational speed and excitation current constant.
