Abstract

This objective of this project is the development of a relay that can estimate frequence, voltage and phase angule for electrical power systems. In order to achieve that, we will employed the optimization method known as Genetic Algorithms (GAs), which will be implemented in hardware (FPGAs) to obtain adequate performance of running time and precision. AG solutions are very interesting since they have shown large tolerance from noise, which are frequent in electrical signals. This project proposes a GA implementation in FPGAs (Field-Programmable Gate Arrays) in order to obtain the electrical signal estimation with high precision. The proposed system was previously simulated in software. The simulations presented excellent results, indicating that the proposal is an adequate approach for frequence relay with advantages when compared with convencinal estimation techniques.
