Distance Relay Interactive Demo

An interactive demonstration of a distance relay using MATLAB, showcasing relay zones and fault impedance calculations.

This basic MATLAB script provides an interactive demonstration of a distance relay, commonly used in power systems for fault detection and isolation. The demo features an R-X diagram displaying relay zones and allows users to simulate faults by adjusting parameters such as fault location, resistance, and direction. The script visually indicates whether the relay would trip for a given fault scenario, aiding in understanding relay operation and settings.

Key Features:

- Interactive sliders and controls for fault configuration

- Visual representation of relay zones on an R-X diagram

- Real-time calculation of apparent impedance and relay trip status

- Educational tool for students and professionals in electrical engineering

Instructions:

1. Run the `distance_relay_demo` script in MATLAB.

2. Use the sliders and dropdowns to configure fault parameters.

3. Observe the relay's response on the R-X diagram and status display.
