Zhejiang NengRong Electric Power On The Role Of Reactive Power Compensation

The general power system user load absorbs active power PL and reactive power QL.
The power supply provides active power PS and reactive power QS (which may be inductive or capacitive), ignoring transformer and line losses, then PS=PL, QS=QL. The power grid without reactive power absorption has the following problems:
The power grid transmits reactive power from a remote location;
The reactive power impact of the load affects the power supply quality of the local power grid and the higher-level power grid.
Therefore, the power system generally requires necessary reactive power compensation for electrical loads to improve the carrying capacity of the power system, purify the power grid, and enhance the quality of power grid.
