Transformações em Sistemas Elétricos de Potência

The triphasic rotative electric machines are essential elements to the electric power systems. Due to the equipment’s dynamic behavior, their equivalent electrical circuits become complex. Exist many ways to ease the projects and analysis resolutions, being the domain transformation one of the most used, and in specific, we cite the Park and Clarke transformation which was initially developed to simplify the calculations. The present article brings a systematic review of these transformations, showing the deductions of Invariant Amplitude and Power Invariant matrix, and the existence of the doubled frequency when the reference angular speed is equal to the synchronous speed, in addition to the visualization of the practical outcomes of the use of these transformations.
