High-Voltage SVG

The LRHSVG series high-voltage static var generators are suitable for 6 kV to 35 kV power grids. The HSVG employs traction‑grade IGBT power devices and a cascaded H‑bridge topology, connecting directly to the grid or via a step-up transformer. Utilizing advanced digital control algorithms, it achieves rapid and reliable tracking of reactive load requirements, making it an ideal on-site reactive power compensation solution for medium- and high-voltage applications. High-voltage static var generators can provide continuous, fast‑response capacitive and inductive reactive power, enabling precise voltage and reactive power regulation to ensure stable, efficient, and high‑quality operation of the power system.

LRAPF Active Power Filter

The LRAPF series active power filters are suitable for low-voltage networks ranging from 0.4 kV to 1.14 kV. They are applicable not only to residential and commercial settings such as office buildings and hospitals, but also to industrial environments including chemical plants, metallurgical facilities, and machinery manufacturing. By monitoring the load current and extracting harmonic currents, the system generates IGBT‑driven counter‑harmonic currents that cancel out harmonics at the point of connection, thereby mitigating harmonic pollution in the grid.

LRSVG Static Var Generator

The LRSVG series Static Var Generator is an upgraded replacement for conventional capacitor‑reactor (SVC) reactive power compensation equipment, suitable for 0.4 kV to 1.14 kV distribution networks. Its core principle relies on power electronics-based power conversion technology: it precisely calculates the reactive component of the load current using Fourier analysis and then actively injects a phase‑opposite inductive or capacitive current into the grid, ultimately achieving a power factor correction level of up to –11.
