Frequently Asked Questions

  • Q1. What is an RPG (Reactive Power Generator)?
    An RPG is a power electronic device that provides fast and dynamic reactive power compensation to maintain stable voltage and improve power factor.
  • Q2. How does an RPG work?
    It uses IGBTs and a voltage source converter (VSC) to inject or absorb reactive power, keeping the grid voltage stable.
  • Q3. What are the advantages of RPG over traditional capacitor banks?
    RPG provides faster response, continuous control, bidirectional compensation (leading and lagging), and better voltage stability.
  • Q4. Where is RPG commonly used?
    In steel plants, wind/solar farms, rolling mills, railways, and industries with heavy inductive loads.
  • Q5. Can RPG improve power factor to unity?
    Yes, RPG can achieve near-unity power factor by dynamically compensating reactive power.
  • Q6. What is the difference between SVC (Static Var Compensator) and RPG?
    • • SVC: Thyristor-based, slower response.
    • • RPG: IGBT-based, faster, and provides smoother control.
