Holding reactive balance, for ensureing the quality of power supply, reduce grid loss, the conveying capacity and the utilization rate of equipment and installations that improve electrical network have weight
The function and significance wanted.
The actual compensation of reactive-load compensation is the front end that compensate for capacitor box access point in fact, so the position installed is leaned on
Proximal end, the effect in fact compensated the best (namely the electric current on bus is the lowest, is lost the fewest)；For front end and end
This difference bright is exactly, if being arranged on front end (being i.e. arranged on incoming line cabinet side) so position of current reduction is incoming line cabinet position
Current reduction, and compensating cabinet aft section electric current does not reduce；If compensating at end, then the electric current on whole bus is all
Can reduce.So the equipment of compensation is the best the closer to end compensation effect.
