Abstract

본 발명은 압축기 역율에 따라 콘덴서의 용량 변화를 주어 부하의 변동에 관계없이 소비전력을 저감토록 한 압축기 역을 보상방법에 관한 것이다.The present invention relates to a method for compensating a compressor station in which a capacity change of a capacitor is changed according to a compressor power factor to reduce power consumption regardless of a change in load.

이러한 본 발명은 압축기 기동시부터 전압과 전류의 위상차가 발생되는 시간을 역율로 환산한 후 환산환 역율을 기준으로 설정된 역율과 비교하고 그 결과에 따라 러닝 콘덴서의 용량을 변화시키도록 스위치를 제어하여 압축기 역율을 보상하게 됨을 특징으로 한다.The present invention converts the time at which the phase difference between voltage and current occurs from the start of the compressor to the power factor, and then compares the power factor set on the basis of the converted power factor and controls the switch to change the capacity of the running capacitor according to the result. To compensate for the compressor power factor.
