Active Power Filter (APF) | Static Var Generator (SVG) | Three-Phase Unbalance Compensation Device
Custom Solutions for Complex Grids · Dynamic Precision Correction · Premium Industrial Choice

As industrial automation and intelligent equipment become widespread, non-linear and impact loads such as variable frequency drives, servo equipment, charging piles, electric arc furnaces and precision instruments are increasingly deployed. Conventional reactive power compensation equipment can no longer solve complex grid problems including harmonic pollution, voltage flicker, three-phase unbalance and reactive power fluctuation, frequently resulting in equipment burnout, production line tripping, precision instrument failure, heavy power losses and accelerated aging of distribution room equipment.

Shanghai Huakun Electric Co., Ltd. has been deeply engaged in power quality management for years. Unlike conventional basic distribution equipment manufacturers, our core flagship and star product line - the premium active power management series - is purpose-built for complex, highly distorted, fluctuating industrial grids. Leveraging self-developed power electronics algorithms and high-speed dynamic response technology, it delivers full-dimension, high-precision grid optimization, making it the preferred premium management solution for mid-to-large industrial enterprises, high-tech industrial parks, data centers and high-end infrastructure projects.

Today, let us take you through the full range of Shanghai Huakun Electric core active power management products, and see the hard-core strength of high-end grid management!

Core Flagship Products | Premium Active Power Management Series

Active power management equipment is the flagship product line of Shanghai Huakun Electric with the highest technical content, the most deployed cases and the best customer reputation. Unlike the passive, static compensation mode of traditional passive compensation, Shanghai Huakun Electric active equipment adopts an intelligent management mode featuring active monitoring, dynamic response, precise cancellation and multi-function in one unit. It adapts to more than 99% of complex industrial power scenarios, thoroughly resolving the industry pain points of traditional equipment that "cannot manage, cannot manage well, and breaks easily."

I. APF Active Power Filter | Core Device for Harmonic Management

(Dedicated flagship device for enterprise high-frequency harmonic pollution)

The APF Active Power Filter is the benchmark product of Shanghai Huakun Electric premium management and currently the most core and effective device for industrial harmonic management. The device collects grid current and voltage waveforms in real time at high speed, precisely analyzes harmonic components through self-developed algorithms, and dynamically outputs reverse compensation current to precisely cancel full-range harmonics from the 2nd to the 50th order, thoroughly eradicating grid harmonic pollution.

Key Product Advantages (Industry Top Config)

Full Harmonic Coverage: Unlike traditional filters that can only manage fixed-frequency harmonics, Shanghai Huakun Electric APF covers the full range from the 2nd to the 50th harmonic, thoroughly purifying the noise and distorted waveforms generated by variable frequency drives, welding machines, electroplating equipment and precision machine tools.

Dynamic Real-Time Response: Microsecond-level response instantly compensates grid waveform distortion with no lag and no dead angles, adapting to complex working conditions with transient fluctuations.

No Secondary Problems: Avoids the harmonic amplification, equipment overload, bulging and explosion problems common with passive filters, ensuring stable and safe operation.

Intelligent Adaptive Operation: Automatically identifies grid pollution levels and dynamically adjusts compensation intensity - no waste at low load, full-load management at high load, maximizing energy savings.

Smart O&M Compatibility: Standard RS485 communication, remote monitoring and data recording, seamlessly integrating into enterprise smart power distribution systems for real-time viewing of grid quality data and equipment operating status.

Key Application Scenarios

Chemical and metallurgical, machining, electroplating and coating, data centers, hospital precision power distribution, rail transit, food and pharmaceutical, automated production lines and other premium working conditions with severe harmonic pollution and interference-sensitive equipment.

II. SVG Static Var Generator | Dynamic Energy-Saving Voltage Stabilizer

(Preferred choice for impact and fluctuating loads)

The SVG Static Var Generator is the premium flagship product of Shanghai Huakun Electric and the core upgraded device replacing traditional capacitor compensation. It completely overcomes the shortcomings of traditional reactive power compensation - slow response, easy over-compensation, poor voltage stabilization and inability to adapt to fluctuating loads - making it the top-config solution for industrial reactive power optimization and voltage management.

Key Product Advantages

Ultra-High-Speed Dynamic Response: Millisecond-level fast compensation, dozens of times faster than traditional equipment, perfectly suited for impact high-power loads such as electric arc furnaces, rolling mills, large air compressors and charging pile clusters.

Multi-Function All-Round Management: Simultaneously delivers dynamic reactive power compensation, voltage flicker suppression and precise power factor voltage stabilization; the enhanced SVG can stack harmonic management, solving multiple grid problems with one device and significantly reducing customer procurement costs.

Unaffected by Grid Voltage: Traditional capacitor compensation degrades significantly with grid voltage fluctuation; Shanghai Huakun Electric SVG adapts to grid conditions and maintains 100% management effect under high and low voltage fluctuations, eliminating low-load over-compensation and high-load under-compensation.

Significant Energy-Saving Effect: Stabilizes system voltage, reduces line losses, eliminates reactive power penalties, saving enterprises large electricity expenses over the long term with high return on equipment investment.

Safe, Durable and Maintenance-Free: Fully modular integrated design with no fragile components, low operating noise and low temperature rise, suitable for long-term 24-hour continuous industrial operation.

Key Application Scenarios

Industrial smelting, stamping and forging, charging pile stations, photovoltaic and wind power supporting, large factory main substations, commercial complexes, municipal key power distribution projects and other scenarios with extremely high requirements for grid stability and energy efficiency.

III. Three-Phase Unbalance Compensation Device | Essential for Distribution Areas & Factory Distribution

(Exclusive solution for difficult distribution area problems)

To address the common problems in domestic low-voltage distribution systems - three-phase load offset, excessive neutral current and transformer phase overloading - Shanghai Huakun Electric independently developed the Three-Phase Unbalance Compensation Device. As the core supporting flagship product of the active power management series, it precisely solves end-of-distribution management challenges.

Key Product Advantages

Automatically monitors three-phase current and voltage deviation in real time, dynamically redistributes three-phase loads and quickly balances three-phase parameters;

Significantly reduces neutral current, solving neutral line heating, cable aging and distribution room odor and heating hazards;

Reduces transformer phase-overloading, improves transformer utilization and extends the service life of distribution equipment;

Also delivers voltage stabilization, noise reduction and loss reduction, adapting to all civil and industrial low-voltage distribution systems.

Key Application Scenarios

Industrial park distribution areas, residential community distribution rooms, commercial supermarkets and office buildings, factory low-voltage distribution systems, and dispersed charging pile distribution scenarios.
