Active Power Filter (APF)

Product Overview

The "Standard APF" adopts a three-level topology and modular design, capable of filtering 2nd–51st harmonics. It focuses on harmonic mitigation, with optional reactive power compensation and three-phase imbalance compensation. It supports single-module operation (drawer-type or wall-mounted) and modular complete-unit configurations.

The "Enhanced APF" builds on the Standard APF with an innovative system architecture comprising active filter modules and a central controller based on a communication network. Harmonic and reactive power extraction is performed in the central controller, which transmits signals to multiple modules via high-speed optical signals. Only one set of CTs is required to parallel multiple modules, solving the limited CT load capacity that restricts conventional APF parallel operation. It also simplifies the structural design of APF power modules and enables online hot-swapping.

Passive Dynamic Reactive Power Compensation Device (SRC)

Product Overview

The A-SRC Series Safety Compensation Cabinet is a dynamic reactive power compensation device. When harmonics exist in the power grid, conventional reactive power compensation risks harmonic amplification. This device is equipped with a tuned compensation branch, making the tuning frequency lower than the system resonance frequency. Near the resonance frequency, the compensation branch always presents a low-impedance inductive characteristic, which avoids resonance and effectively suppresses harmonic currents.

Hybrid Dynamic Harmonic Compensation Device (SVG-S-A)

Product Overview

The A-SVG-S-A Hybrid Dynamic Harmonic Compensation Device combines the functions of a dynamic filter compensation module and passive compensation banks. The device is coordinated and controlled by the dynamic filter compensation module. Relatively stable reactive power is compensated by fixed-capacity passive compensation banks, rapidly changing dynamic reactive power is compensated by SVG modules, and harmonics in heavy-harmonic environments can be filtered by APF modules. This overcomes the problems of conventional passive compensation devices, such as discontinuous compensation, compensation deviation, and inability to eliminate harmonic hazards.

It achieves real-time precise reactive power compensation and harmonic mitigation while avoiding over-compensation caused by sudden reactive power changes, ensuring the power factor remains stable at 1 throughout the compensation process. It is highly suitable for locations with high dynamic compensation requirements and severe harmonic hazards, making it a cost-effective new power quality product.

● User-friendly: 7-inch color touchscreen for easy operation; real-time display of power quality waveforms and data; 500 event records;

● Remote monitoring: diverse communication interfaces, standard communication protocols;

● Cost-effective: combines active and passive technologies; passive reduces cost, active improves performance;

● High reliability: complete protection functions including overvoltage, undervoltage, phase loss, over-temperature, overload, and harmonic protection;

It is suitable for AC 50 Hz circuits with rated operating voltage up to 400 V and rated operating current from 16 A to 800 A for infrequent switching and infrequent motor starting. The breaker provides overload and short-circuit protection, protecting circuits and power equipment from damage.

According to rated ultimate short-circuit breaking capacity (Icu), the breaker is classified into Type S (low breaking), Type L (standard), Type M (higher breaking), and Type H (high breaking).
