Description

산업단지 전력 관리 시스템Industrial Complex Power Management System
본 발명은, 산업단지에 들어선 공장 또는 각종 산업시설의 전력을 통합적으로 관리하여 다수의 공장이나 산업시설이 최적의 계약 전력을 맺도록 하고 그에 따른 전력의 낭비도 줄일 수 있도록 구성된 전력 관리 시스템에 관한 것이다.The present invention relates to a power management system configured to integrally manage the power of factories or various industrial facilities in an industrial complex so that a plurality of factories or industrial facilities can enter into an optimal contract power and reduce power wastage accordingly. will be.
일반적으로, 산업단지에 늘어선 공장이나 산업시설은 전력 공급업체와 계약 전력을 맺게 되는데, 이 계약 전력은 전력수요처가 1년 중에 가장 많이 전력을 사용하는 달을 기준으로 맺어진다.In general, factories or industrial facilities lined up in industrial complexes sign contract power with a power supplier, and this contract power is signed based on the month in which power demanders use the most power during the year.
예를 들어, A 공장이 전력 공급업체와 600kw의 계약 전력으로 계약을 맺는 다는 것은 A 공장이 어떠한 경우에도 600Kw를 초과하는 전력은 사용하지 않겠다는 쌍방 계약이다.For example, if Factory A enters into a contract with a power supplier for 600 kW of contract power, it is a bilateral contract that Factory A will not use more than 600 kW of electricity under any circumstances.
그러나, 위와 같은 계약 전력은, 전술한 바와 같이, 전력 사용처가 1년 중에 가장 많이 사용하는 달의 전력량을 기준으로 맺어져야 하기 때문에, 실질적으로 전력 사용처는 필요 이상의 계약 전력을 체결한 것이라 할 수 있다.However, as described above, the contracted power should be concluded based on the amount of power in the month that the power user uses the most during the year. .
이에 따라, 전력 사용처가 가장 많은 전력을 사용하는 달에는 월 평균 계약 전력에 상응하는 전력을 사용하기 때문에 전기비를 아깝지 않게 지출할 수 있으나, 그렇지 않은 달에는 월 평균 계약 전력에 미달하는 전력을 사용하기 때문에 필요 이상의 전기비를 지출 해야하는 문제점이 있다.Accordingly, in the month when the power consumption site uses the most power, electricity corresponding to the monthly average contracted power is used, so electricity costs can be reasonably spent. Therefore, there is a problem in that you have to spend more electricity than necessary.
따라서, 산업단지의 다양한 전력 사용처로 공급되는 전력을 통합적으로 관리할 필요성이 대두되고 있다.Accordingly, the need for integrated management of power supplied to various power sources in industrial complexes is emerging.
그러나, 산업단지의 들어선 다수의 전력 사용처는, 아파트나 상가 등과는 다르게 광할한 지역에 배치되고, 또한, 대량의 전력을 사용하기 때문에, 관리 업체가 산업단지의 전력 사용량을 통합적으로 모니터링하고 제어하는 것이 어렵다.However, since a large number of power users in industrial complexes are located in vast areas, unlike apartments or shopping malls, and use a large amount of power, the management company must monitor and control the power consumption of the industrial complex in an integrated way. it is difficult
특히, 각 공장마다 상이한 업종을 가지고 있고, 가장 많이 전력을 사용하는 달이 다르기 때문에 산업단지에 공급되는 전력량을 통합적으로 관리하고, 그에 따른 최적의 계약 전력을 도출하는 것에 어려움이 있다.In particular, since each plant has a different industry and the month that uses the most electricity is different, it is difficult to manage the amount of electricity supplied to the industrial complex in an integrated manner and derive the optimal contract power accordingly.
따라서, 본 출원인은, 상기와 같은 문제점을 해결하기 위하여 본 발명을 제안하게 되었으며, 이와 관련된 선행기술문헌으로는, 대한민국 등록특허 제10-1212105호의 '전력 종합 모니터링 시스템'이 있다.Accordingly, the present applicant has proposed the present invention in order to solve the above problems, and as a related prior art document, there is a 'power comprehensive monitoring system' of Korean Patent Registration No. 10-1212105.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 산업단지 내의 전력 사용처에서 사용되는 전력량을 통합적으로 모니터링하고 분석하여 다양한 전력 사용처에서 공동으로 사용할 수 있는 통합 계약 전력을 도출하고, 이 도출된 통합 계약 전력을 바탕으로 각 전력 사용처로 공급되는 전력을 제어할 수 있도록 구성된 전력 관리 시스템을 제공하는데 목적이 있다.The present invention is to solve the above problems, and by integrally monitoring and analyzing the amount of power used in the power usage within the industrial complex, derive the integrated contract power that can be used jointly in various power usage places, and the derived integrated contract An object of the present invention is to provide a power management system configured to control the power supplied to each power source based on power.

또한, 상기 산출부는, 각 전력 사용처가 과년도에 단위 기간 동안 사용하였던 전력 사용량 데이터와 상기 전력량 측정부로부터 측정되는 전력량 데이터를 바탕으로 각 전력 사용처의 전력 사용패턴을 분석할 수 있다.In addition, the calculator may analyze the power usage pattern of each power use destination based on the power usage data used by each power user for a unit period in the past year and the amount of power data measured by the power amount measuring unit.
또한, 상기 과부하 검출부는, 상기 산출부에서 분석된 전력 사용패턴 데이터를 기초로하여, 통합 사용 전력량이 통합 계약 전력을 초과하기 이전에, 연간 허용 전력을 초과하여 전력을 사용할 것으로 예측되는 사용처를 검출하고, 검출된 전력 사용처에 과부하 신호를 전달할 수 있다.In addition, the overload detection unit, on the basis of the power usage pattern data analyzed by the calculation unit, before the integrated power consumption exceeds the integrated contract power, it detects a usage that is expected to use the power in excess of the annual allowable power and transmits an overload signal to the detected power usage.

It can be said that the invention is characterized by
산업단지 전력 관리 시스템(100)은, 도 1 및 도 2에 도시된 바와 같이, 산업단지에 들어선 각 전력 사용처(10)의 전력 사용량을 측정하는 전력량 측정부(110); 상기 다수의 전력 사용처(10)에 공통으로 적용될 통합 계약 전력을 전력 공급업체(20)와 체결하며, 상기 전력량 측정부(110)로부터 측정된 전력량과 상기 통합 계약 전력을 비교 분석하는 통합 관리부(200); 및 상기 통합 관리부(200)에서 분석된 데이터를 바탕으로 상기 전력 사용처(10)로 공급되는 전력을 제어하는 통합 제어부(300);를 포함할 수 있다.Industrial complex power management system 100, as shown in Figures 1 and 2, the amount of power measuring unit 110 for measuring the power consumption of each power use place 10 entered the industrial complex; An integrated management unit 200 that concludes an integrated contract power commonly applied to the plurality of power users 10 with the power supplier 20, and compares and analyzes the power amount measured from the power amount measurement unit 110 and the integrated contract power ); and an integrated control unit 300 for controlling the power supplied to the power use destination 10 based on the data analyzed by the integrated management unit 200 .
먼저, 상기 전력량 측정부(110)는, 산업단지에 들어선 각 공장이나 산업시설에 전력을 전달하는 전력선에 마련될 수 있으며, 전력 사용처로 공급되는 전력을 실시간으로 체크하고, 그 데이터를 무선으로 상기 통합 관리부(200)에 전달할 수 있다.First, the power measurement unit 110 may be provided on a power line that delivers power to each factory or industrial facility entered in an industrial complex, and checks the power supplied to a power source in real time, and the data wirelessly It may be transmitted to the integrated management unit 200 .
전력 사용처는 일반 주택이나 상가와는 다르게 고압 및 대량의 산업용 전력을 사용하기 때문에, 상기 전력량 측정부(110)는, 기계식 전력량계보다는 전자식 전력량계로 구현되는 것이 바람직하다. 더불어, 전력량 측정부(110)는, 공장지대에 늘어선 각 전력 사용처(10)들의 전력 공급선을 물리적으로 통합하는 것이 매우 어렵기 때문에 원격으로 제어될 수 있는 구성을 가진다.Since the place of power use uses high voltage and a large amount of industrial power, unlike a general house or shopping mall, it is preferable that the wattage measurement unit 110 is implemented as an electronic watt-hour meter rather than a mechanical watt-hour meter. In addition, the wattage measurement unit 110 has a configuration that can be remotely controlled because it is very difficult to physically integrate the power supply lines of each of the power users 10 lined up in the factory area.
다시 말해, 본 발명의 일 실시예에 따른 전력량 측정부(110)는, 산업단지에 들어선 각 전력 사용처(110)에 각각 마련되어 전력량을 실시간으로 측정할 수 있고, 그 측정된 데이터를 원격으로 통합 관리부(200)에 전달할 수 있는 구성을 가지는 것이 바람직하다.In other words, the power amount measuring unit 110 according to an embodiment of the present invention is provided at each power use place 110 in the industrial complex to measure the amount of power in real time, and the measured data is remotely integrated into the management unit It is desirable to have a configuration capable of transmitting to (200).
또한, 전력량 측정부(110)는, 단순히 측정기로서의 역할만 수행하지 않고 그 자체가 데이터 허브(Data Hub), 중계기 및 송신기 기능을 수행하도록 구성될 수 있으며, 이에 따라, 별도의 데이터 허브가 설치되지 않도록 한다. 그리고, IPv6에 의한 인터네 IP를 부여받아 사물인터넷(IOT, Internet of Things)으로 구현될 수도 있다.In addition, the wattage measurement unit 110 may be configured to perform the functions of a data hub, a repeater, and a transmitter by itself rather than simply performing a role as a measuring device, and accordingly, a separate data hub is not installed. make sure not to In addition, it may be implemented as an Internet of Things (IOT) by receiving an Internet IP based on IPv6.
위와 같은 구성을 가지는 전력량 측정부(110)는, 수 키로미터 이상 떨어지게 배치된 각 전기 사용처(10)들의 전력량 데이터를, 상기 통합 관리부(200)로 용이하게 전달할 수 있다. 즉, 전력량 측정부(110)는, 측정된 데이터를 먼 거리까지 전달하기 위하여 데이터 신호를 증폭하는 중계부를 더 포함하여 구성될 수 있고, 더불어, 각 전기 사용처(10)들의 전력량 데이터를 통합하여 관리하는 관리 서버를 더 포함하 데이터 허브의 역할도 수행할 수 있으므로 후술할 통합 관리부(200)가 전력량 측정부(110)로부터 제공되는 데이터들을 취합하여 용이하게 분석할 수 있도록 한다.The wattage measurement unit 110 having the above configuration may easily transmit wattage data of each of the electricity users 10 arranged to be separated by several kilometers or more to the integrated management unit 200 . That is, the wattage measurement unit 110 may be configured to further include a relay unit for amplifying a data signal in order to transmit the measured data to a long distance, and, in addition, integrate and manage the wattage data of the respective electricity users 10 . Since it can also serve as a data hub by further including a management server for
상기 통합 관리부(200)는, 산업단지내 각 전력 사용처(10)들의 조합이라고 할 수 있으며, 각각의 전력 사용처(10)를 대신하여 전기 공급업체(20)와 통합 계약 전력을 체결할 수 있다.The integrated management unit 200 may be said to be a combination of each power usage point 10 in the industrial complex, and may conclude an integrated contract power with the electricity supplier 20 on behalf of each power usage point 10 .
이러한 통합 관리부(200)는, 상기 전력량 측정부(110)로부터 측정되는 전력량을 바탕으로 각 전력 사용처(10)의 통합 사용 전력량을 산출하는 산출부(210); 상기 산출부(210)에서 산출된 통합 사용 전력량과 상기 통합 계약 전력을 비교 분석하는 분석부(220); 및 상기 분석부(220)에서 분석된 데이터를 바탕으로 연간 허용 전력을 초과한 전력 사용처를 검출하는 과부하 검출부(230);를 포함할 수 있다.The integrated management unit 200 includes a calculation unit 210 that calculates the integrated power consumption of each power consumption destination 10 based on the amount of power measured by the power amount measurement unit 110 ; an analysis unit 220 for comparing and analyzing the integrated power consumption calculated by the calculation unit 210 and the integrated contract power; and an overload detection unit 230 configured to detect a power usage in excess of the annual allowable power based on the data analyzed by the analysis unit 220 .
상기 산출부(210)는, 전력량 측정부(110)로부터 전달되는 실시간 전력량 데이터를 바탕으로 각 전력 사용처(10)들의 전력 사용량을 취합하여 통합 사용 전력량을 산출할 수 있다.The calculator 210 may calculate the integrated power consumption by collecting the power usage of each power consumption destination 10 based on the real-time power amount data transmitted from the power amount measuring unit 110 .
또한, 산출부(210)는, 각 전력 사용처(10)가 과년도에 단위 기간 동안 사용하였던 전력 사용량 데이터와 상기 전력량 측정부(110)로부터 측정되는 전력량 데이터를 비교 분석하여 각 전력 사용처(10)의 전력 사용패턴을 분석할 수 있다.In addition, the calculator 210 compares and analyzes the power usage data that each power usage destination 10 has used for a unit period in the past year with the power amount data measured by the power amount measurement unit 110, You can analyze the power usage pattern.
즉, 산출부(210)는, 각 전력 사용처(10)의 과년도 전력 사용량 데이터를 가지고 있다. 따라서, 산출부(210)는 과년도 전력 사용량 데이터를 바탕으로 현재 전력 사용처(10)가 사용하고 있는 전력량을 비교 분석하고 이 분석된 결과값을 상기 과부하 검출부(230)로 전달할 수 있다.That is, the calculation unit 210 has previous year power usage data of each power usage destination 10 . Accordingly, the calculator 210 may compare and analyze the amount of power currently being used by the power use destination 10 based on the previous year's power usage data, and transmit the analyzed result value to the overload detection unit 230 .
상기 분석부(220)는, 전기 공급업체(20)와 체결한 통합 계약 전력과 상기 산출부(210)에서 산출한 각 전력 사용처(10)들의 통합 사용 전력량을 비교 분석하고, 그 결과값을 상기 과부하 검출부(230)로 전달할 수 있다.The analysis unit 220 compares and analyzes the integrated contract power concluded with the electricity supplier 20 and the integrated power consumption amount of each of the power users 10 calculated by the calculation unit 210, and the result is the may be transmitted to the overload detection unit 230 .
상기 과부하 검출부(230)는, 전술한 바와 같이, 분석부(220)로부터 분석된 결과값을 바탕으로 연간 허용 전력을 초과한 전력 사용처(10)를 검출할 수 있다.As described above, the overload detection unit 230 may detect the power usage destination 10 that exceeds the annual allowable power based on the analysis result value from the analysis unit 220 .
다시 말해, 과부하 검출부(230), 상기 산출부(210)에서 산출된 통합 사용 전력량이 통합 계약 전력을 초과하면, 다수의 전력 사용처(10) 중에서 연간 허용 전력을 초가한 전력 사용처(10)를 검출할 수 있다.In other words, when the integrated power consumption calculated by the overload detection unit 230 and the calculation unit 210 exceeds the integrated contract power, the power usage 10 exceeding the annual allowable power is detected from among a plurality of power usage targets 10 . can do.
과부하 검출부(230)에서 검출된 전력 사용처(10) 정보는 상기 통합 제어부(300)로 전달되며, 통합 제어부(300)는 해당 전력 사용처(10)로 전력이 공급되는 것을 차단할 수 있다. 즉, 통합 제어부(300)는, 과부하 검출부(230)로부터 검출된 전력 사용처(10)로 전력이 공급되는 것을 차단하는 차단부(미도시)를 더 포함할 수 있다. 참고로, 차단부는, 산업단지 내 각 전력 사용처(10)로 전력을 공급하는 전력 공급선에 차단 스위치, 또는, 차단 밸브의 형태로 구현되어 마련될 수 있다.The information on the power usage destination 10 detected by the overload detection unit 230 is transmitted to the integrated control unit 300 , and the integrated control unit 300 may block the supply of power to the corresponding power usage destination 10 . That is, the integrated control unit 300 may further include a blocking unit (not shown) that blocks the supply of power from the overload detection unit 230 to the detected power usage destination 10 . For reference, the cut-off unit may be implemented in the form of a cut-off switch or a cut-off valve on the power supply line for supplying power to each power use place 10 in the industrial complex.
반대로, 과부하 검출부(230)는, 상기 산출부(210)에서 산출된 통합 사용 전력량이 통합 계약 전력에 미달되면, 각 전력 사용처(10)가 현재 까지는 연간 허용 전력에 포함된 범위 내에서 전력을 사용하고 있는 것으로 판단할 수 있다.Conversely, the overload detection unit 230, when the total amount of power used calculated by the calculation unit 210 is less than the integrated contract power, each power user 10 uses power within the range included in the annual allowable power up to now. It can be judged that it is doing
이때, 과부하 검출부(230)는, 상기 산출부(210)에서 분석된 각 전력 사용처(10)의 전력 사용패턴 데이터를 기초로 하여, 통합 사용 전력량이 통합 계약 전력을 초과하기 이전에, 연간 허용 전력을 초과하여 전력을 사용할 것으로 예측되는 전력 사용처(10)를 검출하고 그 전력 사용처(10)에 과부하 신호를 전달할 수 있다. 즉, 과부하 검출부(230)는, 전력 사용처(10)가 앞으로 소비할 전력량을 추정하고, 그 전력량이 각 전기 사용처(10)에 할당된 허용 전력량을 초과하는지, 또는, 미달되는지를 판단할 수 있으며, 더불어, 그에 따른 대응 신호를 각 전력 사용처(10)에 전달할 수 있다.At this time, the overload detection unit 230, on the basis of the power usage pattern data of each power usage destination 10 analyzed by the calculation unit 210, before the integrated power consumption exceeds the integrated contract power, annual allowable power It is possible to detect the power use destination 10 predicted to use power in excess of , and transmit an overload signal to the power use destination 10 . That is, the overload detection unit 230 estimates the amount of power to be consumed by the power use destination 10 in the future, and determines whether the amount of power exceeds or falls short of the allowable amount of power allocated to each electricity use destination 10 . , in addition, a corresponding signal may be transmitted to each power use destination 10 .
산업단지에 들어선 전력 사용처(10)들은, 대용량 설비의 가동성, 제품의 시장 변동성, 계절성, 비상 상황 등에 따라서 전력 사용량이 급격히 늘어나거나 줄어들 수 있다. Power usage 10 in the industrial complex may rapidly increase or decrease power consumption depending on the operability of large-capacity facilities, market volatility of products, seasonality, emergency situations, and the like.
따라서, 전력 사용처(10)는, 할당된 연간 허용 전력을 초과하거나 미달되는 전력을 사용할 수가 있는데, 여기서, 연간 허용 전력을 초과하는 전력을 사용하게되면 전기 공급업체(20)와 체결되었던 통합 계약 전력을 초과함과 동시에 또 다른 전력 사용처(10)에 할당된 전력을 뺏어서 사용한 셈이 되어 다른 전력 사용처(10)에게 피해를 주고, 전기 공급업체(20)에게 초과 사용 부담금을 지불하게 한다.Accordingly, the power usage destination 10 may use power that exceeds or falls short of the allocated annual allowable power, where, when the power exceeding the annual allowable power is used, the integrated contract power concluded with the electricity supplier 20 , and at the same time, it means that the power allocated to another power usage point 10 is stolen and used, causing damage to the other power usage point 10 and paying an excess usage charge to the electricity supplier 20 .
과부하 검출부(230)는, 이러한 문제점을 사전에 방지하기 위하여, 연간 허용 전력을 초과 사용할 것으로 추정되는 전력 사용처(10)에 과부하 신호를 전달할 수 있다.The overload detection unit 230 may transmit an overload signal to the power usage destination 10 that is estimated to exceed the annual allowable power in order to prevent such a problem in advance.
이때, 상기 통합 관리부(200)는, 상기 과부하 검출부(230)로부터 과부하 신호를 받은 전력 사용처(10)가 상기 전력 공급업체(20)와 별도의 보조 계약 전력을 맺도록 안내하고, 상기 산출부(110)에서 분석된 전력 사용패턴 데이터를 바탕으로 상기 보조 계약 전력을 추전하는 보조 계약 추천부(240);를 포함할 수 있다.At this time, the integrated management unit 200 guides the power user 10 receiving the overload signal from the overload detection unit 230 to enter into a separate auxiliary contract power with the power supplier 20, and the calculation unit ( It may include; a sub-contract recommendation unit 240 for recommending the sub-contract power based on the power usage pattern data analyzed in 110).
이러한 보조 계약 추천부(240)는, 산출부(110)에서 분석된 전력 사용처(10)의 전력 사용패턴과 과부하 검출부(230)에서 분석된 전력 사용처(10)의 예측 소비 전력량을 분석하여 최적의 보조 계약 전력을 산출하고 그 산출된 결과를 전력 사용처(10)에 제공할 수 있다. 그러면, 전력 사용처(10)는 보조 계약 추천부(240)에서 추천한 보조 계약 전력을 전기 공급업체(20)와 별도로 체결할 수 있다.The auxiliary contract recommendation unit 240 analyzes the power usage pattern of the power usage destination 10 analyzed by the calculation unit 110 and the predicted power consumption amount of the power usage destination 10 analyzed by the overload detection unit 230 to optimize The auxiliary contract power may be calculated and the calculated result may be provided to the power use destination 10 . Then, the power usage destination 10 may separately contract the auxiliary contract power recommended by the auxiliary contract recommendation unit 240 with the electricity supplier 20 .
위와 같은, 과부하 검출부(230)와 보조 계약 추천부(240)는, 산업단지의 각 전력 사용처에서 사용된 통합 사용 전력량이 통합 계약 전력을 초과하지 않도록 함과 동시에, 연간 허용 전력을 초과 사용한 전력 사용처(10)가 지속적으로 전력을 공급받을 수 있도록 하여 지속적인 제품의 생산이나 산업적 구동을 수행할 수 있도록 한다.As described above, the overload detection unit 230 and the auxiliary contract recommendation unit 240 prevent the total amount of power used in each power usage area of the industrial complex from exceeding the integrated contract power, and at the same time, the power usage that exceeds the annual allowable power (10) to be able to continuously receive power so that continuous product production or industrial operation can be performed.
참고로, 과부하 검출부(230)와 보조 계약 추천부(240)가 전력 사용처(10)로 과부하 신호 또는 보조 계약 정보를 전달하는 방식은 다양한 공지의 방식이 사용될 수 있으며, 신속한 대응 측면에서는, 전력 사용처(10)의 관리 담당자 단말기로 신호 및 정보를 전달하는 것이 바람직하다.For reference, various well-known methods may be used for the overload detection unit 230 and the auxiliary contract recommendation unit 240 to deliver the overload signal or auxiliary contract information to the power usage destination 10 , and in terms of quick response, the power usage destination It is preferable to transmit signals and information to the terminal in charge of management (10).
한편, 통합 관리부(200)가 전기 공급업체(20)와 체결하는 통합 계약 전력은, 산업단지에 들어선 각 전력 사용처의 과년도 전력 사용량을 기초로 산출될 수 있다. 여기서, 과년도 전력 사용량은, 상기 전력 사용처(10)의 2년~5년 기간 동의 편균 전력 사용량이라 할 수 있다.On the other hand, the integrated contract power that the integrated management unit 200 concludes with the electricity supplier 20 may be calculated based on the previous year's power usage of each power user entering the industrial complex. Here, the power usage in the past year can be said to be the average power usage in the period of 2 to 5 years of the power use destination 10 .
예컨대, A 전력 사용처(10)의 과년도 전력 사용량이 700kw, B 전력 사용처(10)의 과년도 전력 사용량이 400kw, C 전력 사용처(10)의 과년도 전력 사용량이 1100kw, D 전력 사용처(10)의 과년도 전력 사용량이 660kw라고 가정하면, 상기 통합 관리부(200)가 상기 전기 공급업체(20)와 체결하는 통합 계약 전력은 각 전력 사용처(10)의 과년도 전력 사용량을 합한 2860kw라 할 수 있다. 더불어, 각 전력 사용처(10)의 과년도 전력 사용량이 연간 허용 전력량이라고도 할 수 있다.For example, the power consumption of the past year of the A power usage destination 10 is 700 kw, the previous year power usage of the B power usage point 10 is 400 kw, the previous year power usage of the C power usage point 10 is 1100 kw, and the previous year power of the D power usage point 10 is 1100 kw. Assuming that the usage is 660kw, the integrated contract power that the integrated management unit 200 concludes with the electricity supplier 20 may be 2860kw, which is the sum of the previous year power usage of each power use place 10 . In addition, the power consumption in the past year of each power use destination 10 may be referred to as an annual allowable power amount.
이 중에서, A 전력 사용처(10)가 연간 허용 전력량인 400kw를 초가하게 되면, 상기 과부하 검출부(230)로부터 검출될 수 있다.Among them, when the power consumption A 10 exceeds the annual allowable power amount of 400 kw, it may be detected by the overload detection unit 230 .
그러면, 도 3에 도시된 바와 같이, 통합 제어부(300)의 차단부는 과부하 검출부(230)부터 검출된 A 전력 사용처(10)에 전력이 공급되지 않도록 전력을 제어할 수 있다. 그러면, A 전력 사용처(10)는 통합 관리부(200)과 전력 공급업체(20)와 체결한 통합 계약 전력 내의 전력을 더 이상 사용할 수 없다.Then, as shown in FIG. 3 , the blocking unit of the integrated control unit 300 may control the power so that power is not supplied to the A power use destination 10 detected from the overload detection unit 230 . Then, the power source A 10 can no longer use the power in the integrated contract power signed with the integrated management unit 200 and the power supplier 20 .
한편, 위와 같은 A 전력 사용처(10)는, 통합 제어부(300)에 의해 공급되던 전력이 차단되기 이전에, 상기 과부하 검출부(230)로부터 과부하 신호를 전달받을 수 있다. 그러면, A 전력 사용처(10)는 전기 공급업체(20)와 별도로 계약 전력을 맺어야 하는바, 상기 보조 계약 추천부(240)로부터 추천 받은 보저 계약 전력을 전기 공급업체(20)와 체결할 수 있다.Meanwhile, before the power supplied by the integrated control unit 300 is cut off, the above-mentioned power source A 10 may receive an overload signal from the overload detection unit 230 . Then, since the power usage A 10 needs to sign a contract power separately with the electricity supplier 20 , the supplementary contract power recommended by the auxiliary contract recommendation unit 240 may be contracted with the electricity supplier 20 . .
참고로, 각 전력 사용처(10)의 과년도 전력 사용량은, 전기 공급업체(20)가 각 전기 사용처(10)에 고지한 전기 요금서를 기초로 산출될 수 있으며, 이러한 정보는 전기 공급업체(20)로부터 제공받을 수 있다.For reference, the power usage in the past year of each power use place 10 may be calculated based on the electricity bill notified by the electricity supplier 20 to each electricity use place 10 , and this information is provided by the electricity supplier 20 . can be provided from
또한, 상기 통합 계약 전력은, 상기 과년도 전력 사용량에 보조 전력량을 부가하여 산출하는 것이 바람직하다. 왜냐하면, 전술한 바와 같이, 다양한 물리적 요인, 환경적 요인 등으로 인하여 각 전력 사용처(10)에서 소비되는 전력 사용량의 크기 때문이며, 이 변동성에 유연하게 대처하기 위한 측면으로 상기 과년도 전력 사용량의 5~15% 비율을 차지하는 보조 전력량을 부가하여 통합 계약 전력을 산출하는 것이 바람직하다.In addition, it is preferable that the integrated contract power is calculated by adding an auxiliary power amount to the power usage of the previous year. This is because, as described above, due to various physical factors and environmental factors, etc., this is because the amount of power consumed in each power use place 10 is 5 to 15 of the previous year's power usage in order to flexibly cope with this variability. It is desirable to calculate the integrated contract power by adding the amount of auxiliary power occupying the % ratio.
한편, 상기 보조 전력량이 부가되는 비율은 상기 전력 사용처(10)의 전력 사용패턴을 분석하는 상기 산출부(210)에 의하여 보정될 수 있다. 즉, 다음 해에 통합 계약 전력을 산출하기 위하여 상기 과년도 전력 사용량에 부가되는 보저 전력량의 비율은 상기 산출부(210)에 의하여 보정된다.Meanwhile, the rate at which the auxiliary power amount is added may be corrected by the calculator 210 analyzing the power usage pattern of the power usage destination 10 . That is, in order to calculate the integrated contract power in the next year, the ratio of the amount of supplementary power added to the power usage of the previous year is corrected by the calculator 210 .
