PROBLEM TO BE SOLVED: To provide an automatic power factor adjuster for system linkage, capable of properly adjusting the power factor of a power receiving point, even in reverse power flow condition. SOLUTION: An automatic power factor adjuster 1 is equipped with an operation condition setter 3 which is equipped, adding a function to make a delay part 6 have delay times varying with the existence of a reverse power flow at breakage of a leading-phase capacitor bank, a making judging section 4 and a break judging section which has functions of computing and setting the making active power value and the break reactive power value of the value geared to the existence of the reverse power flow, restively, and the delay part 6 which has a function of delaying the operation by the signal outputted by the making judging section 4 and the break judger 5 and varies the delay time with the existence of the reverse power flow. Furthermore, this is equipped with a judgment level switch 2 which has a function of giving a command to make the making judger 4 and the break judger 5 perform operation, switching the making reactive power value and the break reactive power value, according to the existence of the reverse power flow. |
