Simulink System Simulation for Harmonic Analysis and Filter Design

Simulink System Simulation: 10kV bus short-circuit capacity of 10MVA connected through a 10/0.4kV transformer rated at 100kVA with 5% short-circuit impedance. The system supplies an RL load of 50kVA with 0.9 power factor. Power electronic devices generate 5th and 7th harmonic currents of 5A each. A 7th harmonic filter consisting of capacitors connected at the 400V bus works with the transformer to suppress 7th harmonic distortion.
