Smart Hybrid Power Factor Correction (HPFC)
P2 Power Smart Hybrid Power Factor Correction (HPFC) combines the advantages of conventional capacitor-based
reactive power compensation with the fast dynamic response of a Static Var Generator (SVG).
The system integrates Thyristor Switched Capacitors (TSC) with an SVG to provide an efficient solution for
installations where reactive power demand varies significantly. The capacitor stages handle larger portions
of the reactive power requirement in defined steps, while the SVG continuously manages smaller and rapidly
changing reactive power variations.
This hybrid approach minimizes unnecessary capacitor switching while providing smooth and responsive
compensation. It offers an effective balance between performance, reliability, system capacity, and overall
investment cost.
The HPFC system can also provide harmonic compensation and load-balancing functions through the SVG, making
it suitable for industrial facilities with fluctuating and non-linear loads.
Integrated with capacitors, reactors, thyristor, contactor, and apfc relay to provide comprehensive reactive
power management.
How it works?
How Smart Hybrid HPFC Works
The hybrid system consists primarily of two compensation sections:
Thyristor Switched Capacitor (TSC)
The TSC section uses multiple capacitor stages that can be switched electronically according to the reactive
power demand of the electrical system.
It is primarily responsible for handling larger and relatively stable reactive power requirements, reducing
the amount of continuous compensation required from the SVG.
Static Var Generator (SVG)
The SVG provides fast, continuous, and precise reactive power compensation. It responds to rapid changes in
load demand and
supplies the required leading or lagging reactive current without conventional mechanical switching.
The SVG can also contribute to:
-
Harmonic current compensation
- Three-phase load balancing
- Neutral current reduction
- Dynamic power factor correction
By coordinating both technologies through intelligent control, the HPFC system delivers smooth compensation
while reducing unnecessary switching operations.
Smart Hybrid Compensation
Electrical loads in modern industrial facilities can change rapidly, causing significant variations in
reactive power demand. Conventional capacitor banks may not respond quickly enough to these fluctuations and
can result in over-compensation or repeated switching.
P2 Power's Smart HPFC continuously evaluates system conditions and determines the appropriate combination of
capacitor stages and SVG compensation.
The control strategy enables:
-
Automatic capacitor stage management
- Fast response to dynamic loads
- Smooth reactive power compensation
- Reduced unnecessary capacitor switching
- Improved equipment operating life
- Stable power factor under changing load conditions
This coordinated operation makes the HPFC particularly suitable for facilities where load characteristics
change frequently.
Modular SVG Design
The SVG section of the P2 Power Smart HPFC uses a modular architecture for convenient installation,
maintenance, and capacity expansion.
The system can be configured with one or multiple SVG modules according to the required compensation capacity.
Additional modules can be incorporated when the facility's power quality requirements increase.
Available Installation Configurations
-
Rack-mounted modular SVG
-
Wall-mounted SVG
-
Floor-standing SVG
A touch-screen Human Machine Interface (HMI) can be provided for system monitoring, configuration, and
diagnostics.
