Intelligent Active Static Var Generator Panel Svg Series

Overview 

The static var generator (SVG) panel serves as the ultimate solution for high-precision power quality in modern industrial grids. This professional reactive power compensation equipment effectively eliminates voltage flicker while stabilizing the entire electrical distribution network. Furthermore, this Power Factor Correction Device utilizes high-speed IGBT switching to ensure consistent voltage at the receiving end. Consequently, our advanced technology delivers superior reactive power management compared to traditional mechanical switching systems.

Applicable occasion

1.Hoists, rolling mills and other heavy industry equipment (typical impact loads for mining & metallurgical sectors) have the following grid impacts:

• Large reactive power impact, causing grid voltage fluctuations, severe interference to other equipment operation and reduced production efficiency;

• Low power factor, incurring high monthly reactive power penalties;

• Harmonics from partial equipment, endangering grid safety.

2.Oil and gas drilling platform power supply systems (main loads: winches, turntables, mud pumps etc.) are typical impact loads under drilling-specific working conditions, with the following grid impacts:

• Large reactive power impact and low power factor;

• High current harmonics;

• Severe voltage fluctuation & high voltage distortion rate, affecting power supply for control systems, PLC, logging instruments and other equipment.
