You can send me the file at [email protected] , thank you

Simulating a distance relay using MATLAB Simulink involves creating a model of a power system, implementing distance relay logic, and testing its performance under fault scenarios. Here's a summarized step-by-step guide:

Model Power System: Construct a Simulink model representing the power system components.

Fault Injection: Introduce faults at specific locations.

Distance Relay Logic: Implement logic to calculate impedance or distance to faults based on relay settings and signals.

Protection Logic: Design protection logic to trigger relay tripping.

Simulation Parameters: Set time step, duration, and relay settings.

Signal Sources: Generate current and voltage signals for relay inputs.

Visualization: Use Simulink tools to visualize relay behavior.

Testing: Run simulations, analyze relay responses, adjust settings as needed.

Validation: Compare simulation results with real-world expectations.

Documentation: Document model, logic, parameters, and assumptions.

Ensure familiarity with power systems, protection schemes, and Simulink for successful distance relay simulation.
