Both are used to adjust the reactive power in the network. Their direct functions can be considered as: the parallel reactor is used to reduce the voltage of the wind farm node; the parallel capacitor is used to increase the node voltage; several filters are used. This involves the elimination of harmonics generated by wind turbines during electricity production through filtering devices to prevent harmonics from entering the public grid and reducing power quality.
The capacitor compensation is connected from the load side to the load level. end of the power network, and its function is to improve the power factor and reduce the line transmits reactive power and increase the voltage at the load terminals.
The power plant busbar is very close to the power supply (generator) and the voltage is inherently high, so theAdding reactive power compensation makes no sense for the system.
