ABSTRACT
Three-phase induction motors are widely used in industrial applications due to their reliability, operational efficiency, and simple construction. However, these motors are vulnerable to various faults, especially in the stator winding, which can potentially cause severe damage if not supported by an effective protection system.
This study analyzes the power supply protection system for the stator of a three-phase induction motor, emphasizing the implementation and testing of simulations using DigSILENT PowerFactory 2022 software. The research aims to evaluate the performance of overcurrent, overvoltage, and undervoltage protective relays in detecting and mitigating electrical faults such as phase-to-phase and ground faults.
The methodology involves modeling the protection system of the three-phase induction motor in the DigSILENT PowerFactory 2022 environment, setting relay parameters according to industrial standards (IEEE and IEC), and simulating various fault scenarios. Simulation results demonstrate that accurate relay settings significantly influence protection system effectiveness. The overvoltage relay, set at 110% of the nominal voltage (440 V), responds rapidly to faults exceeding threshold values with a trip time of 0.14 seconds. The undervoltage relay, set at 90% of nominal voltage (360 V), differentiates between transient and permanent faults with a delay of 1 second. In overcurrent fault simulations, the relay set at 110% of nominal current with a time multiplier setting (TMS) of 0.3 provides protection with trip times ranging from 0.10 to 0.63 seconds, depending on fault current magnitude. Simulations conducted in DigSILENT PowerFactory 2022 confirm that an appropriate protection system significantly accelerates circuit disconnection and minimizes damage to the induction motor. Optimal relay settings improve operational reliability and safety in industrial motor installations. This study highlights the importance of software-based simulations for designing and
