2.Integrated Power Quality System for Full-Spectrum Grid Improvement

For industrial and commercial facilities, addressing power quality issues requires a coordinated system approach, not isolated components. CNBYG's complete Power Quality System framework combines active and passive technologies to solve both harmonic distortion and reactive power challenges in a single, optimized solution.

At the core of the system are two active compensation technologies:
APF/AHF Active Harmonic Filters: These devices dynamically detect and cancel harmonic currents generated by nonlinear loads such as VFDs, welding machines, UPS systems and switching power supplies. They effectively reduce total harmonic distortion (THD), eliminate neutral line overheating and prevent sensitive equipment from malfunctioning.

SVG/ASVG Static Var Generators: These provide bidirectional, millisecond-fast reactive power compensation, maintaining a stable power factor close to 0.99 and eliminating voltage fluctuations and reactive power backflow issues common in renewable energy and charging station applications.

Complementing these active devices is a full range of passive components including intelligent capacitors, series reactors and automatic controllers, which form cost-effective layered compensation schemes. The system can be customized to match specific load profiles, with options for wall-mounted, rack-mounted and cabinet-style configurations to fit different electrical room layouts.

This integrated approach delivers measurable business outcomes: improved power factor eliminates utility penalty fees, reduced harmonics extend equipment service life, and stable voltage levels reduce unplanned downtime. CNBYG's solutions have been successfully deployed across industries including automobile manufacturing, data centers, photovoltaic and EV charging stations, oil and gas, and injection molding.

Real-world project results demonstrate the impact:
At a large automobile manufacturing plant, deployment of SVG+APF systems raised power factor from 0.72 to 0.99, cutting monthly electricity costs significantly and eliminating welding machine malfunctions.

In a data center project, APF units reduced neutral line current by 60% and lowered transformer operating temperature by 15°C, significantly improving system reliability and cooling efficiency.
For photovoltaic and EV charging stations, SVG systems solved reactive power backflow and voltage fluctuation issues caused by intermittent generation and variable charging loads.

3.BY81 Series Intelligent Power Capacitor: Smart, Reliable Reactive Compensation

For facilities seeking a cost-effective, easy-to-deploy reactive power compensation solution, the Intelligent Power Capacitor (BY81 Series) from CNBYG represents a major advancement over traditional capacitor banks, integrating measurement, control, switching and protection into a single compact module.

Built around self-healing low-voltage power capacitors with an industrial-grade MCU control unit, the BY81 series delivers several key advantages over conventional compensation equipment:

Zero-inrush, zero-crossing switching: Synchronous switching technology ensures precise switching at voltage zero-crossing points, eliminating inrush current, overvoltage, arcing and contact bounce. This extends the service life of the unit to up to 1 million switching operations.
Modular, scalable design: Multiple units can be combined flexibly to match system capacity requirements. Modules automatically elect a master unit and implement fault auto-switching, ensuring uninterrupted compensation even if individual units go offline.

Comprehensive built-in protection: The unit integrates full protection features including over-temperature, over-harmonic, phase-loss and three-phase imbalance protection, reducing the need for external protective components and improving system reliability.

Advanced metering and diagnostics: Built-in power analysis capabilities provide real-time visibility into voltage, current, power factor and temperature, with an intuitive display for easy operation and troubleshooting.

Low power consumption: Standby power consumption is less than 1W, minimizing self-loss and contributing to overall energy savings.

The BY81 series supports both delta (△) and star (Y) connection configurations, with a rated voltage range of 220V to 380V and an operating temperature range from -40°C to +40°C, making it suitable for deployment in harsh industrial environments. It communicates via RS-485 and can integrate seamlessly with CNBYG's power quality controllers and larger SVG/APF systems for coordinated system-level control. The product complies with DL/T842-2003 and GB/T22582-2008 power industry standards, with consistent performance verified by full automated testing.

Compared to traditional fixed capacitor banks, intelligent power capacitors reduce installation time by 50%, require less cabinet space, and deliver more accurate, responsive compensation. They are ideal for commercial buildings, manufacturing plants, municipal infrastructure and small industrial facilities looking to upgrade their power factor correction systems.

Technical teams are available to support projects worldwide.

Q: What causes frequent start-stop of power quality compensation equipment?
A: Frequent start-stop is typically caused by three issues: first, a blocked or stuck cooling fan triggering over-temperature protection; second, grid voltage fluctuations exceeding ±20% outside the normal operating range; third, harmonic distortion rates exceeding 30% triggering current-limiting protection thresholds. Operators should check these three areas first when troubleshooting.
