Key Aspects of Compensation Systems
- Capacitive VAR Compensation (Power Factor Correction):
- Purpose: Inductive loads (motors, transformers) cause lagging power factor and voltage drops. Capacitors provide leading reactive power to neutralize this, reducing energy costs and improving voltage levels.
- Methods: Fixed capacitor banks (for constant loads) or automatic switched capacitor banks (for varying loads).
- Dynamic Solutions: Static VAR Compensators (SVC) and Static VAR Generators (SVG) offer fast, dynamic, and precise VAR control for fluctuating loads.
- Harmonic Compensation:
- Need: Modern power electronics (VFDs, UPS) introduce harmonics (,,), causing overheating and equipment malfunction.
- Methods: Passive filters (tuned capacitors) provide both capacitance and harmonic filtering, but run the risk of resonance.
- Active Harmonic Filters (AHF): Measure network harmonics and inject cancelling currents, providing highly effective, dynamic mitigation.
- Need: Modern power electronics (VFDs, UPS) introduce harmonics (
- Combined Solution (VAR + Harmonics):
- Active Power Filters (APF) and SVG solutions are often combined to solve both issues in modern grids with high renewable energy penetration, enhancing power quality and stability.
- Hybrid systems (e.g., Capacitor Banks + Passive/Active Filters) offer a cost-effective balance between bulk power correction and harmonic mitigation.
- System Impact:
- Proper compensation prevents resonance, reduces total harmonic distortion (THD), and optimizes the efficiency of the electrical infrastructure.
