<P>PROBLEM TO BE SOLVED: To provide a load voltage control system at the time of single operation of a generator in which the load voltage can be sustained at a predetermined level even at the time of single operation of the generator and stabilized load operation can be ensured. <P>SOLUTION: An on-load tap changing transformer 3 connected with a generator 1 through a circuit breaker 2 interlinked with the generator is connected with a system 5 through a power receiving circuit breaker 4 and the on-load tap changing transformer 3 is connected with a load 7 through another transformer 6. In such a power supply system, an automatic voltage regulator 8 is connected to the high voltage side of the on-load tap changing transformer 3 and when the circuit breaker 2 interlinked with the generator is closed, the power receiving circuit breaker 4 is opened, and the generator 1 is operated independently because it is not linked with the system 5, the detector of the on-load tap changing transformer 3 is switched such that the automatic voltage regulator 8 regulates the on-load tap changing transformer 3 to have a predetermined voltage on the high voltage side thus sustaining the voltage of the load 7 at a predetermined level. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
