Test Plan For Real-Time Modeling & Simulation Of Single Pole Switching Relays, Ram Mohan Sanaboyina
Test Plan For Real-Time Modeling & Simulation Of Single Pole Switching Relays, Ram Mohan Sanaboyina
University of New Orleans Theses and Dissertations
A real-time simulator (RTS) with digital and analog input/output modules is used to conduct hardware-in-the-loop simulations to evaluate performance of power system equipment such as protective relays by exposing the equipment to the simulated realistic operating conditions. This work investigates the use of RTS to test relays with single-pole-switching (SPS) feature. Single-pole switching can cause misoperations due to fault arc during reclosing of the breakers. Through this investigation, a test procedure appropriate for the testing SPS relays has been developed. The test procedure includes power system modeling for real time simulation, relay test setup, and test plan. HYPERSIM real-time simulator …
