A flicker improvement effect evaluating system evaluates an effect of improvement of voltage flicker in a power system to which a static reactive power compensator is to be introduced. A system voltage operating unit operates a compensation current and a system impedance of the power system, based on actually measured data of system voltage and load current read from a data reading unit. Based on the results of operations and the actually measured data, a not-yet-improved system voltage at present and an improved system voltage attained when the static reactive power compensator is provided on a bus are simulated. By a flicker meter, flicker values of the not-yet-improved system voltage and improved system voltage amplified by an amplifying circuit are measured, and from the flicker values, the rate of improvement attained by the static reactive power compensator is operated.
A flicker improvement effect evaluating system for evaluating an effect of improving voltage flicker attained by a compensator introduced to a power system having a load connected to a prescribed bus, comprising:
