高圧需要家における電力品質を考慮した低圧進相コンデンサの制御手法

Generally, Static Capacitors (SCs) for improving the power factor are installed in high voltage consumers and they are controlled by Automatic Power Factor Controller (APFC). However, the optimal capacity of SC can reduce the loss of the transformer and suppress the harmonic currents. Therefore, this paper proposes the novel control method of the SC for improving plural power quality, such as power factor, voltage and the harmonic currents comprehensively. The proposed method is implemented to the DSP board as the controller. The effectiveness of the method is confirmed by using Real-Time Simulator (RTS) and the experimental setup.
