3-Phase Balanced Star Connected Network using Simscape
Simscape model of a 3-phase balanced star network showing phase voltage, line voltage, and neutral current analysis.
🔹 Overview
This project demonstrates a 3-phase balanced star (Y) connected network using MATLAB Simscape. It helps in understanding phase voltage, line voltage, line current, and neutral current behavior in balanced systems.
🔹 Model Description
The model consists of:
- Three-phase AC voltage sources
- Balanced star-connected load
- Voltage measurement blocks for:
- Line voltages (VRY, VYB, VBR)
- Phase voltages (VRN, VYN, VBN)
- Current measurement blocks for:
- Line currents (IR, IY, IB)
- Neutral current
- Scope for visualization of waveforms
🔹 Key Concepts Covered
- Three-phase balanced system
- Star (Y) connection
- Line voltage vs Phase voltage
- Line current equals Phase current
- Neutral current in balanced system
🔹 Output Observations
- Line voltage is √3 times phase voltage
- Line current equals phase current
- Neutral current is zero (balanced condition)
- All three phases are 120° apart
🔹 Mathematical Relations
Line voltage:
V_L = √3 × V_Ph
Line current:
I_L = I_Ph
Neutral current:
I_N = 0 (for balanced system)
🔹 How to Run
