Low-voltage Svg StaticVar Generator Module

Category:

The KS‑SVG low-voltage static var generator is a three-phase full-bridge voltage-source converter composed of fully controlled power electronic devices—IGBTs. By adjusting the phase and magnitude of the AC-side output voltage of the bridge circuit, it can either absorb or inject reactive power to meet specified requirements, thereby achieving dynamic reactive power compensation. This low-voltage static var generator is primarily used in low-voltage systems to improve the power factor while simultaneously compensating for harmonic currents and unbalanced currents. It features fast response, high compensation accuracy, and flexible compensation modes, capable of compensating both capacitive and inductive reactive power.

Product Overview

Operating Mode

Dynamic, grid CT mode In this mode, the KS‑SVG measures the reactive and unbalanced currents on the supply side and adjusts them to zero. This is accomplished via a closed-loop control strategy. It is the most widely used, highly accurate, and recommended approach. By employing this mode, the full performance potential of the KS‑SVG can be realized.
Dynamic Mode In dynamic mode, the KS‑SVG generates a dynamic current based on feedback from the CT, which can be obtained from the CT located on the supply side. This is the recommended approach. In this mode, the full performance of the KS‑SVG can be realized.
Fixed Compensation Model In this mode, the KS-SVG, acting as a fixed lagging or leading current source, supplies a settable lagging or leading reactive current to the system. When multiple KS-SVG units are operated in parallel, all KS-SVGs share a single current transformer (CT) to regulate the power factor.

Low Voltage Power Capacitor

Low-voltage dry-type shunt capacitors are energy‑saving devices used for power factor correction in low‑voltage power systems operating at 50 Hz or 60 Hz. They reduce reactive power losses and improve voltage quality. The KD‑H dry‑type eco‑friendly capacitor is manufactured using advanced German technology in a Class 100 cleanroom environment. Under vacuum conditions of 10–3 bar, the components are heated while protective gas is injected. This process effectively removes air and moisture from within the capacitor, preventing electrode oxidation and localized discharge. Following this sophisticated manufacturing sequence and rigorous factory acceptance testing and quality assessments, the capacitors achieve exceptional stability and an extended service life. Depending on the application, they are available in single‑phase and three‑phase configurations.

Original Imported Low Voltage Capacitor

The original imported MOKN series capacitors are highly popular in the Chinese market thanks to their proprietary technology. During production, these capacitors are filled with nitrogen (N2), and they incorporate a unique SINECUT grooving process along with a distinctive metal‑treatment technique. Moreover, their optimally positioned internal core ensures that the device’s capacitance remains stable even under the severe stress of high‑voltage AC surges and negative pressure conditions. This hallmark feature makes the MOKN series particularly well suited for applications involving controlled equivalent DC currents and surge protection.

Low Voltage Intelligent Capacitor

The KD‑Z series intelligent low‑voltage power capacitors are a next‑generation reactive power compensation device designed for 0.4 kV low‑voltage distribution networks, delivering high efficiency and energy savings, reducing line losses, and improving the power factor and power quality. They consist of an intelligent measurement and control unit, a synchronous switching circuit, a line protection unit, and low‑voltage power capacitors. These units replace conventional automatic reactive power compensation systems that rely on discrete components—such as smart controllers, fuses, composite switches or mechanical contactors, thermal relays, low‑voltage power capacitors, and indicator lights—wired together inside and on the surface of switchgear cabinets. By eliminating the bulky, unwieldy design of traditional systems, this new generation of low‑voltage reactive power compensation equipment offers superior compensation performance, a more compact footprint, lower power consumption, reduced costs, greater cost savings, enhanced flexibility in application, simplified maintenance, extended service life, and higher reliability, thereby meeting the increasingly stringent requirements of modern power grids for reactive power management.
