HYSVGC Series Hybrid Static Var Dynamic Compensation Device

Product Description

Product Features

■ Fast Dynamic Response

• 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.

■ Intelligent Control & Modular Design

• 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.

■ High Compensation Accuracy

• 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.

■ Excellent Harmonic Suppression

• SVG module provides fast harmonic compensation with a response time <10ms.
• Able to suppress 2nd–13th order harmonics depending on system requirements.

■ Flexible Capacity Configuration

• 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.

■ Safe and Reliable Operation

• 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.

■ Stable and Efficient Performance

• 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.

Working Principle

• ICMS intelligent controller
• SVG active compensation module
• LC passive compensation module

1. SVG provides fast response to dynamic reactive power fluctuations.
2. LC module provides large-capacity steady-state compensation.
3. The ICMS controller continuously monitors load conditions and coordinates the real-time switching of SVG and LC modules.
4. This hybrid approach eliminates over-compensation and under-compensation problems common in traditional TSC/TCR systems.
5. The device maintains stable power factor and suppresses harmonic pollution.
