Introduction of BY95-ASVGC Hybrid Dynamic Filtering Compensation Device
BY95-ASVGC Hybrid Dynamic Filtering Compensation Device：6 Major Advantages
Advanced hybrid technology effectively reduces harmonics
The BY96-ASVGC integrates active power filter (APF) and static VAR generator (SVG) technologies to simultaneously suppress harmonics and perform dynamic VAR compensation. It eliminates more than 95% of harmonics (2nd to 50th), including those from non-linear loads such as inverters and rectifiers, and reduces total harmonic distortion (THD) to less than 5%. This hybrid design overcomes the limitations of standalone passive filters, which have the risk of resonance, and active filters, which are expensive and have limited capacity.
Real-time power quality optimization
With a response time as fast as milliseconds (<15 ms), the device dynamically corrects voltage fluctuations, flicker, and three-phase imbalance. It stabilizes grid voltage to within ±2%, ensuring compliance with international standards such as IEEE 519. This is critical for sensitive facilities (e.g., data centers, laboratories) where voltage sags or harmonics can disrupt operations.
Efficient reactive power compensation
SVG modules provide continuous capacitive/inductive reactive power (±50Mvar range), improving power factor to above 0.99. Unlike capacitor-based solutions, they prevent overvoltage and resonance, thereby reducing grid losses by 5-12% and lowering electricity bills. For high energy users such as factories, this means saving millions of dollars in fines each year.
Resonance prevention and system safety
Our hybrid dynamic filtering uses impedance adaptive control to avoid harmonic amplification. The APF actively suppresses the risk of resonance, while the multi-branch passive filter targets specific frequencies (5th, 7th, 11th). This extends equipment life by more than 30% by preventing transformer/capacitor overheating and insulation degradation.
Energy saving, emission reduction and accelerated return on investment
By significantly reducing losses caused by harmonics (e.g. skin effect of cables, core losses of transformers), the system can reduce energy waste by 8-15%. For a 10MW power plant, this means saving about 420,000 kWh of electricity per year. Combined with reduced maintenance costs and avoided downtime, the return on investment can be achieved within 2-3 years.
Smart Grid Integration and Scalability
Embedded IoT sensors and AI-driven analytics enable remote monitoring via the cloud platform. The modular design supports parallel expansion of up to 10 units (rated voltage 650V) to accommodate growing load demands. Real-time data is synchronized with EMS/BMS to enable predictive maintenance and energy optimization, creating a future-oriented industrial grid.
Operation Principle of BY95-ASVGC Hybrid Dynamic Filtering Compensation Device
The BY96-ASVGC low voltage hybrid dynamic reactive power compensation device is a cutting-edge solution designed to address key power quality challenges, including harmonic mitigation, reactive power compensation and three-phase unbalance correction. The system uses advanced hybrid technology to integrate the functions of a static reactive power generator (SVG) and an active power filter (APF) into a compact device, improving power quality with unparalleled efficiency in a variety of industrial and commercial applications.
Dynamic reactive power compensation:
The device continuously monitors the reactive power demand of the grid using real-time data from voltage and current sensors. It utilizes an IGBT-based inverter to generate precise reactive power (both capacitive and inductive) to maintain a power factor ≥ 0.99, minimizing energy loss and achieving optimal voltage stability. This feature is critical for industries with fluctuating loads, such as manufacturing plants and data centers, where reactive power imbalances can lead to equipment inefficiencies and increased electricity costs.
Active harmonic filtering:
BY96-ASVGC is equipped with an advanced harmonic detection algorithm that identifies and eliminates harmonic distortion up to the 50th order by injecting reverse current into the grid. This active filtering mechanism can effectively mitigate problems caused by non-linear loads, such as harmonic resonance and equipment overheating, ensuring compliance with international standards such as IEEE 519.
Three-phase unbalance correction:
The system actively balances phase currents by redistributing reactive power between phases, thereby reducing transformer overload and extending equipment life. This feature is especially beneficial for residential and commercial grids with uneven load distribution.
Intelligent control system:
A high-performance DSP controller coordinates all functions and dynamically adjusts compensation strategies based on real-time grid conditions. An intuitive 7-inch touchscreen interface allows users to monitor key parameters (such as THD, power factor, and harmonic content) and configure settings remotely, increasing operational flexibility.
Applications of BY95-ASVGC Hybrid Dynamic Compensation Device
Industrial manufacturing and heavy machinery
The BY96-ASVGC is designed to address critical power quality challenges in industrial environments dominated by high-power nonlinear loads. In steel mills, chemical plants, and automotive manufacturing plants, equipment such as variable frequency drives (VFDs), arc furnaces, and welders generate severe harmonic distortion (up to the 50th order) and reactive power imbalance, leading to voltage instability, transformer overheating, and the risk of violating IEEE 519 standards. The device's hybrid dynamic filtering function combines active harmonic elimination (through APF technology) with dynamic reactive power compensation (through SVG functionality) to eliminate harmonics in real time while maintaining a power factor ≥0.99. For example, in a steel mill's rolling mill, the BY96-ASVGC reduces total harmonic distortion (THD) from 18% to less than 5% and stabilizes voltage fluctuations during load transients, extending the life of motors and PLC systems by 30%.
Commercial buildings and data centers
In commercial complexes, data centers, and medical institutions, nonlinear loads such as LED lighting, elevators, and UPS systems generate severe harmonic pollution and reactive power demand. For example, data centers equipped with UPS arrays often face N-line overcurrent problems due to third harmonic currents, which can overload transformers and cause downtime. The modular hybrid design of the BY96-ASVGC solves these problems by combining passive filtering with active harmonic injection, reducing the N-line current by up to 80% (for example, in a 2MW data center, the N-line current is reduced from 586A to 78A).Key applications include:
• Voltage Stabilization: Maintaining ±1% voltage tolerance for sensitive equipment such as MRI machines and server racks minimizes the risk of downtime and equipment damage.
• Energy cost optimization: Improve power factor to above 0.98, avoid utility company fines and reduce electricity bills by 10-15% through efficient reactive power management.
• Remote Monitoring: The 7-inch touchscreen interface and cloud connectivity allow facility managers to track THD, power factor and harmonic spectrum in real time for proactive maintenance.
With its small footprint (50 kvar+25A to 500 kvar+250A), the device is ideal for retrofitting existing switchgear rooms in office buildings and hospitals, ensuring seamless integration without disrupting operations.
Renewable energy grids and microgrids
As solar farms and wind installations expand, inverter switching and intermittent power output can cause voltage fluctuations and harmonic distortion. BY96-ASVGC’s hybrid dynamic compensation provides critical support to the grid by:
• Dynamic reactive power support: Stabilizes voltage during rapid changes in solar irradiance or wind gusts, ensuring compliance with grid codes such as VDE-AR-N 4105 and EN 50438.
• Harmonic suppression: Filter out the harmonics generated by solar inverters and wind turbine converters, reduce THD to below 4%, and enhance grid compatibility.
• Grid-forming capability: Simulates synchronous generators to provide inertia and frequency support to islanded microgrids, an important function for off-grid renewable systems.
In distributed solar installations, the device’s scalable modular design (30 kvar+15A modules for rooftop systems and 500 kvar+250A modules for utility-scale farms) enables flexible deployment. For wind farms, its millisecond response (<5ms) mitigates voltage sags during turbine startup, enhancing grid stability and reducing equipment wear.
