PROBLEM TO BE SOLVED: To provide a consumer voltage stabilization system in a low voltage system of a power distribution system that coordinately performs appropriate reactive power compensation on every no-load power compensation device in the case of distributed installation of a plurality of reactive power compensation devices in correspondence with low voltage system consumers.SOLUTION: The consumer voltage stabilization system so configured that a plurality of reactive power compensation devices 9A-9F distributedly installed in a low voltage system I regulate individual voltages at consumer ends P2 is configured to reduce the low voltage system I into an equivalent low voltage system in which a pole transformer 3 connects to a single consumer via a low voltage distribution line 14 and a single incoming line, then on the reduced low voltage system, compute a reactive current component of reactive power required to cancel a variation in voltage in the low voltage system on the basis of a primary side voltage of the pole transformer 3, an impedance of the reduced low voltage system and a current of the consumer end P2, and divide the computed reactive current component by the number of consumers 6A-6F to produce a proportional compensation current to be supplied. |
