Abstract
PURPOSE: To reduce the variation of AC bus voltage, by balancing the quantity of reactive power fed and the consumption of reactive power.
CONSTITUTION: Phase is controlled by a phase controller 27 so that the consumption of reactive power of regular and reverse converters 1, 11 slowly be changed when starting and stopping the regular and reverse converters in case of high load operation, and the ON-OFF control of a condensive reactive power element and a lag reactive power element of a reactive power feeder is performed by matching the time change of the consumption of reactive power and timing in roder that the lack of reactive power or the excess of reactive power to the consumption of the reactive power can be compensated, thus balancing the quantity of reactive power fed and the consumption of reactive power. Consequently, the variation of AC bus voltage in case of stating and stop can be reduced.
