要約(英語): Voltage distortion of high-order harmonic has occurred at a 22kV customer. There are only two customers who are supplied by this 22kV distribution feeder. Therefore, it is likely that induction heater of another customer have become the harmonic source. In 22kV customer, so far, there are no cases where such voltage distortion has occurred. It is necessary to understand the actual condition for this case and to clarify the effective countermeasure.As a result of analyzing the measured data, even though the high-order harmonic current generated from the induction heater is small, the voltage distortion of the high-order harmonic was increased. This is suggests that the current generated by the induction heater and the impedance conditions of the distribution system generate voltage distortion. We have constructed an analysis model, and have considered a countermeasure utilizing shunt capacitor by simulation. Based on the results of the simulation, we have demonstrated the effect of the shunt capacitor.
