The RWSVGC low-voltage hybrid active dynamic reactive power compensation device is installed in low-voltage distribution networks to improve voltage quality, enhance reactive power compensation management, and ensure stable and efficient power supply performance. It is an upgraded and extended solution based on traditional automatic low-voltage reactive power compensation systems. Through the integration of active and passive technologies, RWSVGC provides faster response, higher accuracy, and better adaptability to modern electrical loads.
The system combines SVG modules and LC components to deliver ultra-fast compensation.
SVG modules provide rapid dynamic reactive power regulation.
LC branches offer high-capacity compensation with minimal losses.
The hybrid structure ensures smooth transitions, avoiding under-compensation and over-compensation during sudden load fluctuations.
Equipped with ICMS intelligent control and monitoring platform.
Real-time display of power parameters, waveform data, compensation ratio, and operating status.
Supports multiple working modes and flexible configuration of SVG + LC modules.
Each branch is monitored independently to ensure stability and reliability.
Compensation accuracy ≥ 97%.
Power factor adjustable up to 0.99.
Effectively reduces system voltage fluctuations and reactive power losses.
Minimizes harmonics within the LC compensation components, preventing switching surge issues common in traditional systems.
SVG module provides fast harmonic compensation with a response time <10ms.
Able to suppress 2nd–13th order harmonics depending on system requirements.
Compensation range adjustable from −1 to +1 (relative per-unit compensation).
SVG and LC components can be combined in various ratios to match different load characteristics.
Typical configurations can use 30kvar–300kvar capacity modules.
Built-in protections: overvoltage, undervoltage, overload, overcurrent, short circuit, overheating, unbalanced current, THD alarms, and phase-loss protection.
Automatic fault diagnosis, automatic switching, and automatic recovery.
Improves voltage quality and network stability.
Reduces transformer and cable losses caused by low power factor or load imbalance.
Ideal for applications with strong impact loads, variable loads, and nonlinear equipment.
The RWSVGC hybrid compensation system consists of:
ICMS intelligent controller
SVG active compensation module
LC passive compensation module
SVG provides fast response to dynamic reactive power fluctuations.
LC module provides large-capacity steady-state compensation.
The ICMS controller continuously monitors load conditions and coordinates the real-time switching of SVG and LC modules.
This hybrid approach eliminates over-compensation and under-compensation problems common in traditional TSC/TCR systems.
The device maintains stable power factor and suppresses harmonic pollution.
