P2 Power Hybrid Power Factor Correction (HPFC) Panel combines conventional reactive power compensation with advanced active power-quality technology in a single integrated solution. The system is designed to manage reactive power, power factor, and harmonic distortion simultaneously.
By combining switched capacitor stages with an IGBT-based Active Harmonic Filter (AHF), the HPFC system can provide both bulk reactive power compensation and fast, continuously adjustable correction for rapidly changing electrical loads.
The solution can help maintain the desired power factor while controlling harmonic distortion in accordance with applicable power- quality requirements, including IEEE 519, where the complete system design and site conditions support compliance.
Integrated with capacitors, reactors, thyristors, and alpha series power modules to provide comprehensive power quality management.
The P2 Power Hybrid HPFC uses two complementary compensation technologies.
Switched capacitor banks provide economical compensation for the larger and relatively stable portion of the reactive power demand. Depending on the application, capacitor stages can be switched using contactors or thyristors.
The IGBT-based active compensation section responds rapidly to changing load conditions by continuously regulating reactive current and compensating selected harmonic components.
The hybrid architecture is particularly useful in facilities where electrical loads vary rapidly and conventional capacitor banks alone cannot provide sufficiently fast correction.
Integrated Reactive Power & Harmonic Compensation
Combines switched capacitor technology with an active harmonic compensation stage to address both reactive power and harmonic distortion within one system.
Advanced IGBT-Based Compensation
High-speed power electronics enable rapid adjustment of compensation current and harmonic filtering for dynamic and non-linear loads.
Wide Harmonic Compensation Capability
The active filtering section can be configured to address harmonic components up to the 51st order, subject to system rating and application requirements.
Flexible Capacitor Switching
Capacitor stages can be configured with:
The appropriate switching technology can be selected according to load characteristics and response-time requirements.
Harmonic Resonance Protection
Detuned reactors can be incorporated into the capacitor circuit to reduce the risk of harmonic resonance and protect the compensation system.
Heavy-Duty Capacitor Configuration
High-voltage-rated capacitor banks can be selected for demanding industrial applications and extended operating life.
Dynamic Power Factor Correction
The active compensation section provides smooth, continuously adjustable reactive power correction, helping maintain the desired power factor under changing load conditions.
Load Imbalance Compensation
With appropriate system sizing and configuration, the HPFC can also provide three-phase load balancing to improve distribution-system performance.
Compact System Architecture
The integrated design can reduce the overall installation footprint compared with deploying separate reactive power and harmonic compensation systems.
Monitoring & Communication
Multiple HMI, metering, communication, and remote-monitoring options can be incorporated according to project requirements.
Flexible Enclosure Options
The system can be supplied in different enclosure configurations and protection levels, including IP20 to IP55, depending on installation conditions and project requirements.
LV & MV Electrical Systems
The HPFC concept can be engineered for LV or MV electrical distribution systems, depending on the selected compensation architecture and application requirements.
Benefits
P2 Power Hybrid HPFC is particularly suitable for facilities with substantial reactive power demand combined with harmonic-generating or rapidly fluctuating loads.
