Industry Demand
The massive integration of nonlinear loads such as modern power electronic devices into the power grid has severely impacted power supply quality. The extensive use of various power electronic switching devices and frequent load fluctuations are the primary sources of interference, leading to a series of adverse effects.
currently, the most ideal solution is to adopt SVG (static var generator) to enhance grid stability, increase transmission capacity, eliminate reactive power surges, filter out harmonics, and balance three-phase power grids.
SVG represents the latest technology in the field of reactive power compensation today. The basic principle of SVG is to utilize high-power, switchable power electronic devices (such as IGBT) to form a self-commutated bridge circuit, which is then connected in parallel to the power grid through a reactor. By appropriately adjusting the magnitude and phase of the output voltage on the AC side of the bridge circuit, the device can absorb or generate reactive current, achieving the purpose of dynamic reactive power compensation.
the use of anti-interference technology with active power filters (APF) is crucial for suppressing high-order harmonics in power systems and improving power supply quality.
