DSP Relay Protection Experiment Report
In this paper, an overcurrent relay is built and investigated using DSP, TMS320F2812. The overcurrent protection is chosen since it is used as a major protection in the distribution systems. This document outlines laboratory experiments focused on various electrical protection relays, including IDMT Over Current, Differential, and Negative Sequence relays. It details objectives, apparatus, theoretical background, procedures, and results for each experiment, emphasizing safety protocols. Various DSP techniques such as Fast Fourier Transform (FFT), Discrete Fourier Transform (DFT) and Wavelet Transform along with Artificial Neural Networks (ANN) can be used to detect spurious signals and disturbances. The relays are capable of performing complex processing faster and with higher accuracy since the processing using DSP are optimized for real-time signal.
