도 2는 본 발명의 일 실시예에 따른 전력관리 시스템을 이용하여 생산설비의 이상 여부를 검출하는 과정을 설명하기 위해 제공된 흐름도이다. 2 is a flowchart provided to explain a process of detecting an abnormality in a production facility by using the power management system according to an embodiment of the present invention.

도 2를 참조하면, 제어부(200)는, 각각의 생산설비의 이상 여부를 검출하기 위해, 전력 측정부(100)를 통해, 생산설비별 전력량을 측정하면(S210), 이를 수신하여, 동일한 스펙의 생산설비들의 전력량의 평균값을 산출하고, 산출된 평균값의 표준편차 1.2배 이내에 해당하는 데이터들의 최대값 및 최소값를 이용하여 전력량 데이터의 표준값의 범위를 산출할 수 있다(S220). Referring to FIG. 2, when the control unit 200 measures the amount of power for each production facility through the power measurement unit 100 in order to detect whether each production facility is abnormal (S210), it receives the same specification. The average value of the wattage of the production facilities of is calculated, and the range of the standard value of the wattage data can be calculated by using the maximum and minimum values of the corresponding data within 1.2 times the standard deviation of the calculated average value (S220).

이때, 데이터의 표준값의 범위는, 전체 전력량 평균값 데이터 중 대부분(약 99% 이상)이 평균값의 표준편차 1.2배 이내에 분포하기 때문에, 이를 기준으로 산출되는 것이 바람직하다. At this time, the range of the standard value of the data is preferably calculated based on this since most (about 99% or more) of the average value of the total amount of power is distributed within 1.2 times the standard deviation of the average value.

즉, 제어부(200)는, 각각의 생산설비들의 전력량이 전력량 데이터의 표준값의 범위를 초과하는지 판단하며(S230), 표준값의 범위를 초과하는 경우(S230-Y), 동일한 스펙의 생산설비에 비해 과도하게 전력을 사용하는 것으로 판단하여, 이를 관리자에게 전달하고, 관리자가 점검을 수행하도록 안내할 수 있다(S240). That is, the control unit 200 determines whether the amount of power of each production facility exceeds the range of the standard value of the power amount data (S230), and when it exceeds the range of the standard value (S230-Y), compared to production facilities of the same specification. It is determined that the power is used excessively, it is transmitted to the manager, and the manager may guide the inspection to be performed (S240).

다른 예들 들면, 제어부(200)는, 수신된 데이터를 가공하여, 특정 생산설비의 전력량 데이터를 요일별, 일별, 시간대별로 산출하고, 산출된 요일별, 일별, 시간대별 전력량 데이터를 동일한 스펙의 다른 생산설비의 요일별, 일별, 시간대별 전력량 데이터들과 함께 가공하여, 요일별, 일별, 시간대별 전력량 데이터의 표준값을 산출할 수 있다.
