DSP Relay Protection Experiment Report

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.

Relay Protector Appearance

Relay Protector Appearance

Protective relays can monitor large AC currents by means of current transformers (CT's), which encircle the current-carrying conductors exiting a large circuit breaker, transformer, generator, or other devices. The rectangular devices are test connection blocks, used for testing and isolation of instrument transformer circuits. Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to.

What is dual power supply for relay protection

What is dual power supply for relay protection

A self or dual-powered supply is often used in the design MCCBs or ACBs with an electric trip unit circuit. In this reference design the rectified input charges the capacitor to generate the output voltage. The regulated DC output voltage is set by a Zener Diode and a MOSFET shunt regulator. The 7SR46 dual powered protection relay is to be showcased at Enlit Europe, taking place in Frankfurt from November 29 to December 1. Due to their often remote location, secondary substations do not always have a battery to provide power to electronic equipment such as protection relays. Electronic trip units are true RMS sensing-over-current trip devices, requiring no external supply for their basic functioning.
