Universal Power Flow Controller (UPFC)
High-frequency MOSFET semiconductor platform engineering real-time voltage, impedance, and phase angle regulation to eliminate electrical losses.
State-of-the-Art Power Flow Regulation
The Universal Power Flow Controller (UPFC) manufactured by PRA Energy Solution is an active semiconductor-controlled system designed specifically for highly inductive environments such as water works pumping schemes, continuous-duty motor drives, and industrial manufacturing plants.
Unlike traditional capacitor-based APFC panels which are static, slow to respond, and prone to harmonic resonance, the UPFC uses high-speed MOSFET semiconductor switching to dynamically regulate phase angle, reduce current draw by 10%ā15%, and maintain a unity power factor under rapid load variations.
15 Salient Engineering Features
Complete technical specification of the UPFC power flow regulation system:
Active Power Factor Optimization
Improves power factor to near unity (0.98ā0.99 lag), meeting and exceeding all DISCOM regulatory standards.
Active KWH & KVAH Reduction
Directly cuts apparent and active energy consumption, leading to verified 2% to 10% electricity bill savings.
KVA Demand Suppression
Lowers total apparent KVA demand on incoming transformers, allowing additional plant capacity expansion.
Regulatory DISCOM Rebates
Enables facilities to qualify for state DISCOM high-power-factor incentives (up to 2.5% to 7% bill rebates).
Zero Low-PF Surcharges
Permanently eliminates penalty charges, reactive energy draw penalties, and low-power-factor levies.
2nd Level Harmonic Mitigation
Active filtering suppresses 2nd-level electrical harmonics, protecting upstream transformers and sensitive digital controls.
Maximum Demand (MD) Relief
Reduces recorded Maximum Demand peaks, directly lowering the recurring monthly fixed billing slab.
