Zusammenfassung: | The present invention relates to a remote calculating method for a metering out fit (MOF) ratio error using an advanced metering infrastructure (AMI)-based smart meter and to an AMI server using the same. According to an embodiment of the present invention, the remote calculating method for an MOF ratio error using an AMI-based smart meter comprises: a step of calculating voltage and current of each phase for a fixed period through calculation information transmitted from a smart meter; a step of calculating the amount of effective power of a three-phase three-wire type and a three-phase four-wire type by each phase after the fixed period; a step of comparing the preset threshold with a difference of the amount of effective power of the calculated three-phase three-wire type and three-phase four-wire type by each phase; and a step of calculating the ratio error of MOF by calculating a calculation error rate of the relevant phase when an abnormal ratio error is determined in the relevant phase from the comparison results. The present invention is able to calculate the ratio error of MOF in real time.
본 발명은 AMI 기반의 스마트미터를 이용한 MOF 비오차의 원격 산정 방법 및 이를 이용한 AMI 서버에 관한 것으로, 본 발명의 일실시예에 따른 AMI 기반의 스마트미터를 이용한 MOF 비오차의 원격 산정 방법은, 스마트미터로부터 전달된 계량정보를 통해 일정주기 동안 각 위상의 전압과 전류를 계산하는 단계; 일정주기 이후에, 각 상별 3상 3선식 및 3상 4선식에 대한 유효전력량을 계산하는 단계; 상기 계산된 각 상별 3상 3선식 및 3상 4선식에 대한 유효전력량의 차이를 기설정된 임계값과 비교하는 단계; 및 상기 비교 결과로, 해당 상의 비오차 이상 발생이 판단되면, 해당 상의 계량오차율을 계산하여 MOF(Metering Out Fit)의 비오차율을 계산하는 단계;를 포함한다. |
