Overview: With the development of modern power electronics technology, power electronic devices have been widely used, and a large amount of reactive power reciprocating exchange exists between power equipment and power grids. Reactive power is divided into: inductive reactive power (current vector lags voltage, such as motors, transformer coils, thyristor converters, etc.), capacitive reactive power (current vector leads voltage, such as capacitors, cable transmission and distribution lines, power electronics advanced control, etc.), and fundamental reactive power (reactive power equal to the grid frequency). Reactive power does no work, but it occupies grid capacity and conductor cross-sectional area, causing increased line voltage drop and overloading of power supply and distribution equipment.
