Abstract
본 발명은 전자식 전산 전력량에 관한 것으로, 종래에는 출력부에 1 : 1로 연결되어 있는 조건값으로 디멘드 예측값만 가지고 온, 오프시키므로, 순차적이며 강제적일 수 밖에 없다. 이때는 예측 전력량이 아주 적은 값의 초과가 예상되더라도 부하가 적게 걸리는 부하를 골라 차단시키지 못하고, 큰 부하일지라도 연결되어 있는 부하를 무조건 차단시킨다.The present invention relates to the amount of electronic computer power, and in the related art, only the demand prediction value is turned on and off as a condition value connected to the output unit at 1: 1, which is sequential and compulsory. At this time, even if the estimated power amount is expected to exceed a very small value, the load that is less loaded may not be selected and the connected load is unconditionally blocked even for a large load.
이러한 경우는 또한 외부 센서등에 의한 입력조건, 내부의 고장, 장애등에 의한 조건, 에너지 양이나 역율에 의한 조건적 부하 제어 및 시간조건에 의한 제어등을 기대하기 어려운 문제점이 있다. 따라서, 본 발명은 내외부로부터 입력신호, 조건을 받아 부하를 조건적으로 제어하는 사용자에 의한 프로그래머블한 로직 제어기능을 수행하여 조건적이며, 연결된 선을 바꾸는 작업없이도 제어가 가능하도록 한다.In this case, there is also a problem that it is difficult to expect an input condition by an external sensor, a condition by an internal failure, a failure, a conditional load control by an amount of energy or a power factor, and a control by a time condition. Accordingly, the present invention performs a programmable logic control function by a user who receives an input signal and a condition from inside and outside to conditionally control a load, thereby enabling control without changing a conditional and connected line.
