Wall-Mounted Active Power Filter Compensation Module
The active filtering compensation module is a modular product specially developed by Guangda Electric for dynamic harmonic mitigation in 0.4 kV power supply systems. Connected in parallel with the grid, it uses an external current transformer to continuously monitor the load current. Leveraging DSP, FPGA, and CPLD chips, along with cutting-edge rapid harmonic mitigation and reactive power extraction technologies, it swiftly analyzes the harmonic and reactive components of the load current. Based on user-defined setpoints, it generates PWM pulses to drive a bidirectional converter composed of three-level IGBT modules, thereby producing compensation currents that meet grid requirements. This enables precise, real-time compensation of harmonic and reactive currents, ultimately enhancing power quality.
Active modular power quality products comprise three categories: static var generators (SVG), three-phase unbalance compensators (ASVG), and active filters (APF).

Reactive Power Compensation Module
The ZBMGD-P intelligent filtering and compensation module integrates a fuse‑type knife‑fusible switch, a contactor (composite switch), filtering capacitors, and filtering reactors into a single unit. By replacing the conventional distributed configuration, it achieves modularity, standardization, and simplified design. While providing reactive power compensation, it also offers harmonic filtering and over‑temperature protection, thereby ensuring the safest possible operation of the equipment.

ZBMGD Intelligent Filtering and Compensation Module
The ZBMGD‑T intelligent filtering and compensation module is Guangda Electric’s third‑generation product, specifically designed for 0.4 kV dynamic reactive power compensation systems to reduce line losses, improve the power factor, and enhance power quality. It comprises a knife‑fused switch, thyristor modules, an intelligent measurement, control, and protection unit, capacitors, and reactors. The module features temperature and current displays, as well as protections against overtemperature, overcurrent, thyristor breakdown, and harmonic distortion, and supports remote monitoring of each module’s operating status. Its independently developed fast switching technology is ideally suited for impact loads and other applications requiring rapid reactive power compensation on site.
