Working Principle BY92-SVG/50kvar-0.4/4L-B（SVG）

IGBT-based inverter core and dynamic compensation mechanism
BY92-SVG/50kvar-0.4/4L-B static VAR generator (SVG) uses high-frequency IGBT inverter modules to perform dynamic reactive power compensation in three-phase low-voltage systems. By quickly switching current in a three-phase four-wire configuration, it injects or absorbs reactive current to balance the reactive power in the power system and stabilize the grid voltage. The SVG in this power system can detect power quality harmonics and load imbalance in real time, and adjust the reactive power in the power system within milliseconds (less than 5 milliseconds). Dynamic reactive power compensation control ensures accurate correction of inductive/capacitive imbalances to meet the reactive power compensation needs of factories and commercial buildings. The integrated anti-interference filter shields the system from electromagnetic noise, ensuring reliability in low-voltage electrical environments.
Intelligent control and real-time monitoring unit
At the heart of the SVG static VAR generator is its AI-driven intelligent control system, which coordinates both reactive power compensation and harmonic suppression. Using a DSP processor, the system continuously analyzes current, voltage waveforms, and power supply harmonics (up to the 25th), dynamically adjusting the SVG power factor correction voltage to achieve a power factor close to 1. The system’s real-time monitoring interface provides insight into power quality in power system indicators, enabling proactive maintenance. Its adaptive correction algorithm autonomously resolves three-phase imbalance in a three-phase grid, while anti-harmonic technology suppresses harmonic distortion (THD <3%). Designed for low-voltage grids (0.4kV), the system optimizes reactive power ratios and minimizes energy waste in power distribution.
Harmonic filtering and unified compensation module
This SVG electrical solution integrates a multi-level H-bridge structure to unify harmonic and reactive compensation integration. The module uses PWM-based harmonic suppression technology to actively eliminate harmonics in the power supply while managing reactive current for static reactive compensation. By injecting anti-harmonic current, it can neutralize the distortion caused by non-linear loads such as inverters and LED drivers, ensuring compliance with power quality standards. The reactive power devices within the module are able to adapt to fluctuating grid conditions and provide seamless reactive current compensation in three-phase power systems. The module is compact and wall-mounted, suitable for installation in space-constrained low-voltage equipment from solar power plants to industrial plants, and its rugged design can withstand various environmental pressures.
Adaptive grid stability and efficiency optimization
BY92-SVG is equipped with a three-phase unbalanced adaptive correction system that detects and eliminates asymmetrical loads in three-phase power systems. The system uses FPGA logic to redistribute reactive power compensation between phases, eliminate voltage deviations and prevent motor overheating. Combined with dynamic reactive power compensation control, the system improves the power quality of the power system network by smoothing voltage sags/swells and reducing transmission losses. The intelligent power factor correction system ensures efficient energy saving (loss reduction of up to 30%) by adjusting the ratio of reactive power to active power. Its IP54 protection grade housing and wide operating temperature range (-25°C to +60°C) ensure its durability and is ideal for low-voltage equipment in harsh environments. This SVG static VAR generator redefines power distribution and provides a future-oriented solution for power grids that focus on resilience and sustainability.
