Overview
The Static Var Generator (SVG) is a leading solution for reactive energy compensation, designed to meet the demands of modern networks facing challenges like increased harmonics and voltage fluctuations from renewable energy sources. Its DSP-controlled IGBT topology ensures effective phase compensation for both inductive and capacitive loads, while also correcting phase imbalances. With resistance to harmonics and resonance, the SVG offers a maintenance-free solution that can easily integrate into any network configuration, making it suitable for today’s evolving energy landscape.
Applicable occasion
1.Hoists, rolling mills, and other heavy industry applications are typical impact loads, primarily found in mining and metallurgical industries. They have the following impacts on the power grid:
The reactive power impact is large, resulting in power grid voltage fluctuations, serious interference with the operation of other equipment, reducing production efficiency;
Low power factor, monthly need to pay a large amount of reactive power fines;
Some devices produce harmonics, endangering the safety of power grid.
2. The main loads of the oil and gas drilling platform power supply system include winches, turntables, mud pumps, etc. Due to the specific conditions of drilling, the system represents a typical impact load. The impacts on the power grid are as follows:
Large reactive power impact, low power factor;
High current harmonics;
The voltage fluctuation is serious and the voltage distortion rate is high, which affects the power supply of the control system, PLC, logging instrument and other equipment.
