Three-phase imbalance can lead to negative-sequence and zero-sequence currents in the power grid, which can also pollute the power grid in the form of harmonics.
As a crucial component of modern power quality management, low-voltage active power filters (APFs) not only effectively suppress harmonics but also exhibit various additional functions in reactive power compensation.
Due to the extensive use of renewable energy generation equipment and power electronic devices, the power grid often generates numerous harmonics, voltage fluctuations, and reactive power issues, thus affecting power quality and system stability. In this
In the power systems of modern industrial, commercial buildings, and public facilities, power quality directly affects equipment lifespan, operating efficiency, and energy costs.
Active power filters (APFs), as a type of power electronic device that dynamically suppresses harmonics and compensates for reactive power, exhibit unique advantages in managing interharmonics.
Low-voltage static var generators (SVGs), by eliminating capacitor banks and adopting fully controlled power electronics technology, not only completely avoid the fatal flaw of traditional LC resonance compensation methods, but also, with millisecond-leve
