Modern electrical systems face increasing challenges from fluctuating loads, poor power factor, reactive power demand, and phase imbalance. Industrial facilities, commercial buildings, manufacturing plants, data centers, renewable energy systems, and utility networks require intelligent power quality solutions to maintain efficient and reliable operation.
The Delta PQC Series Static Var Generator (SVG) is an advanced reactive power compensation solution designed to improve power factor, reduce reactive power losses, correct load imbalance, and enhance overall electrical system efficiency. Unlike traditional capacitor banks, SVG technology provides dynamic, real-time compensation that responds instantly to changing load conditions.
By continuously monitoring electrical parameters and injecting compensating current into the power system, the Static Var Generator ensures that the current and voltage remain closely aligned, resulting in near-unity power factor and optimized power system performance.
How Static Var Generator Works
The operating principle of a Static Var Generator is similar to an Active Power Filter, but its primary focus is reactive power compensation rather than harmonic mitigation.
When inductive or capacitive loads create a phase difference between current and voltage, the SVG automatically detects this deviation and generates a compensating current with the required phase angle.
The process includes:
- Continuous monitoring of load current and voltage.
- Detection of reactive power demand.
- Calculation of phase angle differences.
- Generation of leading or lagging compensation current.
- Real-time correction of power factor.
- Balancing of phase loads and reduction of neutral current.
As a result, the current phase becomes closely aligned with the voltage phase, achieving a power factor close to unity (1.0) and improving overall energy efficiency.
SVG System Structure
Delta PQC Series SVG features a modular architecture designed for flexibility, scalability, and simplified maintenance.
A complete SVG system typically includes:
- One or multiple SVG modules.
- Optional Liquid Crystal Monitor and Control Panel (LCM).
- Standard SVG cabinet or customized enclosure.
- Integrated circuit breakers.
- Cable terminals.
- Surge Protection Device (SPD).
Each SVG module functions independently, allowing users to easily increase or decrease compensation capacity by adding or removing modules according to system requirements.
