<P>PROBLEM TO BE SOLVED: To allow voltage at a power reception end to be adjusted for each of power reception facilities where Ferranti phenomenon or voltage rise due to concentration of a leading current occurs on a 6 kV bus line, and to enable countermeasure against occurrence of voltage rise to be performed at low cost in comparison with the case of permanently installing shunt reactors on 6 kV distribution line poles and electric stations. <P>SOLUTION: A voltage adjustment system comprises: a shunt reactor 5i through which a delay current flows when it is connected to a power reception facility; and moving means 4 movable to an installation location of the power reception facility while being loaded with the shunt reactor 5i. When information relating to a power reception facility where Ferranti phenomenon, in which voltage at a power reception end rises in comparison with voltage at a power transmission end, or voltage rise due to concentration of a leading current occurs on a 6 kV bus line is acquired, the moving means 4 loaded with the shunt reactor 5i is moved to the installation location of the power reception facility. When the shunt reactor 5i is connected to the power reception facility, the delay current flows through the shunt reactor 5i and thus, the voltage at the power reception end can be adjusted for each power reception facility. <P>COPYRIGHT: (C)2013,JPO&INPIT |
