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.

High-Voltage Automatic Reactive Power Compensation and Harmonic Elimination Device


The high-voltage automatic reactive power compensation and harmonic elimination device is a new product developed to meet the demands of enhanced comprehensive automation in 6 kV and 10 kV power systems. The device primarily comprises a modular vacuum contactor, capacitors, reactors, a discharge unit, a controller, and a microprocessor-based protective relay. It can adjust the system’s power factor in response to changes in grid conditions, thereby reducing transformer and line losses, increasing transmission capacity, and maximizing the economic efficiency of transmission and distribution equipment, while also suppressing system harmonics and improving power quality.
