General Overview. In a perfect power system, the electricity flows smoothly in a regular wave pattern. But in real life, machines that don’t use power evenly cause irregular currents called reactive and harmonic currents, which can reduce the quality of power. Power companies set rules for maintaining good power quality, including a minimum power factor—a measure of how efficiently electricity is used. If this isn’t met, there can be extra charges..

Purpose of PQR. PQR is a medium-voltage reactive power compensation system for 3-phase 11/6.6 kV networks. It controls current distortion, improves power factor, and operates with ~1.1% losses, ensuring high efficiency vs LT solutions..

Why Power Stack. Why So Many PS Units in Series? Instead of one big unit, the system uses many smaller PS modules because: Advantages Modularity → easy maintenance (replace one unit) Scalability → add/remove units as needed Redundancy → system can sometimes run even if one fails Voltage sharing → each unit handles part of the total voltage Typical Real-World Use This kind of setup is commonly used in: Railway traction systems (25 kV AC lines) High-power industrial drives HV converter stations.
