Reactive power compensation components
<ul id="wvut3"></ul>
Static reactive power compensation generator is IGBT as the core of SVG System, Flexible AC Transmission System (FACTS) is
one of the main devices, it represents the current power system reactive power compensation technology new development
direction. SVG parallel in the power grid, equivalent to a controllable reactive current source, its reactive current can quickly
follow the load reactive current changes, can quickly and continuously provide capacitive and inductive reactive power, to
achieve appropriate voltage and reactive power control, to ensure the power system stable, efficient and high-quality
operation.
SVG uses high-power electronic devices (such as IGBT) that can be turned off to form a self-commutating bridge circuit.
After the reactor is connected to the power grid in parallel, the amplitude and phase of the output voltage on the AC side of
the bridge circuit can be properly adjusted, or the current on the AC side can be directly controlled, so that the circuit can
absorb or emit reactive current that meets the requirements and realize the purpose of dynamic reactive power compensation.
