High-Voltage Dynamic Reactive Power Compensation Device

The GD‑SVG series high‑voltage dynamic reactive power compensation devices are IGBT‑based reactive power compensation systems that can rapidly and continuously deliver either capacitive or inductive reactive power. They enable control at the point of measurement to maintain constant reactive power, constant voltage, and a stable power factor, thereby ensuring the stable, efficient, and high‑quality operation of the power system. The GD‑SVG significantly improves power quality at the connection point between the load and the public grid, for example by increasing the power factor, balancing three‑phase voltages, suppressing voltage flicker and fluctuations, and mitigating harmonic distortion. With their ease of operation, high performance, and exceptional reliability, the SVG product series is specifically designed to meet users’ pressing needs for improving the power factor of transmission and distribution networks, controlling harmonics, and compensating negative‑sequence currents.

Fast-acting vacuum circuit breaker

Fast-acting vacuum circuit breaker

During a short-circuit fault: the fast‑acting vacuum circuit breaker rapidly discharges the energy stored in its energy‑storage capacitor, and the electromagnetic repulsive force generated by eddy currents directly drives the breaker to achieve rapid opening. It can detect a short-circuit fault within 2 ms and complete opening within 4 ms after receiving the command, enabling it to interrupt the fault during the initial phase of the short‑circuit current, thereby preventing overreaching tripping of upstream switches. The trip‑current threshold is customizable. In the absence of a fault: the fast‑acting vacuum circuit breaker is fully compatible with conventional medium‑voltage circuit breakers in terms of operating procedures, physical dimensions, and wiring configurations. It can detect a short-circuit fault within 2 ms and complete opening within 4 ms after receiving the command, allowing it to interrupt the fault during the first peak of the short‑circuit current and preventing overreaching tripping of upstream switches. The trip‑current threshold is also configurable.

Wall-Mounted Active Power Filter Compensation Module

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).
