Abstract

The present undergraduate research intends to focus on power transformer protection tests in the closed-loop simulations, also known as hardware-in-the-loop (HIL). The protection tests are performed with the relay hardware receiving the data generated during a real-time simulation and interacting with the simulations. The candidate has acquired background with the transmission line distance relay HIL test with the UNICAMP Real Time Digital Simulator (RTDS). However, UNICAMP simulator can only externalize analogic signals that are amplified and injected into the IED. The present research seeks to work with an updated protocol that is being used in digitalized substations (Sampled values, Goose). The Unicamp RTDS does not have the hardware necessary to implement such tests and this is an important knowledge that the candidate should acquire during his internship at University of Manitoba under the supervision of Professor Athula Rajapakse. The test system is already modeled in RSCAD and is based on a Brazilian system. The protection to be studied is the power transformer one because the candidate is currently working with transformer modeling and typical transformer switching transients.
