Abstract

PURPOSE:To prevent hunting by forecasting after-operation of a controlled equipment by the control effective value to be stored and preventing the sending of an operation control command when the control effective value is higher than the blind sector value. CONSTITUTION:Voltage/reactive power control (VQ control) device 1 detects the passing reactive power Q of a transformer 3 and the voltage V2 of a bus conductor 6, makes comparison/operation treatment with reference reactive power and reference voltage, and makes an on/off control of an on-load tap changing transformer LRT, a power condenser SC and a shunt circuit reactor SR. First of all, the present value of voltage V2 and reactive power Q is taken in by control of the controller 1 to decide the present position at each coordinates. A control equipment for this position of coordinates can be selected, the control effect of an actual equipment obtained through the previous controls is stored, and the control effect value and the blind sector value selected from the memory data are compared. As the result, when the control effective value is lower than the blind sector value, a control command is outputted, and at the same time, the actual control effective value of a controlled equipment is taken in and stored.
