Working  Principle of BY95-ASVGC  Hybrid Dynamic Filtering Compensation Device

1. Hybrid dynamic filtering technology
The core functionality of the device combines the functions of an active power filter (APF) and a static VAR generator (SVG). The APF continuously monitors the real-time current waveform to identify harmonic components (2nd to 51st) generated by non-linear loads such as inverters. It uses an advanced FFT-based algorithm to generate offset harmonic currents to eliminate distortion, thereby reducing total harmonic distortion (THD) by up to 95%. At the same time, the SVG module dynamically injects or absorbs reactive power to stabilize voltage levels and maintain a power factor ≥0.98, thereby eliminating reactive power fluctuations and grid instability.

2. Intelligent full control system
BY95-ASVGC is equipped with a DSP-based controller that analyzes key parameters (voltage, current, power factor) in real time. The system uses an adaptive control strategy to optimize the compensation ratio between active and passive components. For example, during transient loads (such as motor starting), the SVG can quickly output reactive power within a few milliseconds, while the APF can suppress harmonics caused by surges. This synergy ensures dynamic balancing of all phases and corrects three-phase imbalance problems by adjusting the compensation current of a specific phase.

3. Multifunctional integration
The device serves as a unified solution for a variety of power quality issues:
• Harmonic Mitigation: Actively eliminates harmonic currents to protect equipment from overheating and premature failure.
• Reactive power optimization: Continuously adjusts capacitive/inductive reactive power to minimize energy losses and increase grid efficiency.
• Voltage stabilization: Mitigates voltage sags/swells caused by fluctuating loads by regulating reactive power flow.
• Three-phase balance correction: Uses phasor analysis to detect phase differences and apply targeted compensation, reducing neutral current by up to 80%.

4. Adaptive compensation mechanism
BY95-ASVGC uses a self-adjusting algorithm to adapt to different load profiles. For example, in industrial environments with cyclic loads such as welding machines, the system dynamically switches between pre-programmed compensation modes such as harmonic mitigation priority and reactive power optimization. This flexibility ensures optimal performance in a variety of applications, from data centers equipped with high-frequency UPS systems to manufacturing plants with heavy inductive loads.

5. Enhanced reliability and protection
The device is built with rugged components including:
• Overcurrent/overvoltage protection: Immediate shutdown in fault conditions to prevent equipment damage.
• Thermal management: Intelligent cooling system maintains operational stability even in extreme temperatures.
• Redundant control architecture: Dual-core processors ensure uninterrupted operation even if one control module fails.

6. Grid compatibility and energy saving
By reducing harmonic pollution and optimizing reactive power, BY95-ASVGC achieves:
• Reduced energy costs: Reducing line losses can save 5-15% on electricity bills.
• Extend equipment life: Reducing thermal stress on transformers and capacitors can extend their service life by 30-50%.
• Grid compliance: Ensure compliance with international standards (such as IEEE 519) for harmonic limits and power factor requirements.
