THD Harmonic Analysis

Reactive Power Compensation and Resonance

  • The equality of inductive reactance and capacitive reactance in an electrical circuit is called as resonance.
  • The most common type of resonance occurs between the mains and the compensation system.
  • Overcurrent and overvoltages resulting from resonance cause damage to power system components.
  • The response of the system impedance to the effective harmonic frequencies should be analysed.
