要約(英語): High-voltage supplied customers install static capacitors to improve their power factor (PF) at their interconnection points. However, most of them are excessive and this makes system PF in distribution network extremely-leading. This is caused by two economical grounds. One is because utilities assume excess reactive power for their load to get full discount for PF improvement. The other is expensiveness of static capacitor (SC) controllers.The authors propose new SC control logic that involves simple electric current measurement without voltage or reactive power, which enables economical controller productions. The basic functions are mounted on verification test devices and evaluated in fields for several months. This paper presents the logic and verification test result.
