Abstract

Using three-phase synchronous generators basic units in power plants, the main source for feeding alternating current. The electromagnetic force (e.m.f) given by these generators depend mainly on the number of pairs of poles in the Member excitement and speed of rotation cycles of the generator. Since the number of pairs of electrodes are part of the structural arrangement of generator will not change due to overload, but it will be the adoption of frequency only on the speed with which revolves where the generator. The power transformers are the heart's main power plants and power transmission and delivery to the consumer and based on the work of the converted electric depends on electromagnetic induction, so the performance of work directly related to the frequency in which they operate. It is through this research will be identified on the behavior of each of the born Synchronous and transferred electrical in the case of low frequency. This is done checks of laboratory and compared to examine the system simulation through the language of MATLAB has been done to change the frequency and noting the effect on each of the power factor, efficiency and organization of voltages for each of the converted and born Synchronous and show results in the form of charts.
