<p><P>PROBLEM TO BE SOLVED: To enable a stable distribution system operation by enabling power supply to a distribution system including an unexpected large consumer in a conventional manner and by maintaining the voltage of the entire power distribution lines at appropriate values. <P>SOLUTION: The distribution system operation system for supplying power to a distribution system including a large consumer is equipped with multiple loops configured by linking a plurality of power distribution lines 3 via a circuit breaker 8, and with a voltage monitoring controller 16 for controlling the voltage in the distribution system. The voltage monitoring controller 16 estimates the voltage of the entire power distribution line based on the measured information of the plurality of nodes in the distribution system, and when the voltage is not within an appropriate range, the voltage monitoring controller controls the voltage in the distribution system by controlling the voltage regulators 1, 9 set in the distribution system. The multiple loops include distribution lines with and without a branched load. The voltage monitoring controller 16 controls the voltage in the distribution system by enlarging the appropriate range of the voltage in the distribution line without the branched load relative to the distribution line with the branched load, from among the plurality of distribution lines constituting the multiple loops. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
