ABSTRACT Asynchronous motors are the most preferred engines in the industry due to factors such as their stable speed, economic and operational safety. Recently, asynchronous motors have been used as generators in the power generation sector and especially in wind turbines in renewable energy systems. In the study, the asynchronous motor with a squirrel cage was turned by a universal motor and operated as a generator by providing excitation by a capacitor. According to the ohmic and inductive load at the generator output changes in the current drawn by the driving machine, in the terminal voltage, in the capacitor current, in the number of revolutions and in the output frequency were observed according to the capacity change and the state of the capacitor
being connected to the star/delta. With the value of the excitation capacitor and the star / delta connection shape, it has been observed that the terminal voltage and the current drawn by the drive motor from the grid change. As the speed of the drive
motor increases, the current values of the end voltage, frequency, capacitor and drive motor increase. The asynchronous motor
does not go into the generator mode when load is connected to the system output. In this research, it was aimed to contribute to
the study of asynchronous motor as generator.
