본 고안은 가구별, 세대별로 최대수요전력을 감시 제어하는 장치에 관한 것 으로, 보다 상세하게는 가정용 전기 검침기를 통해 입력되는 아날로그 신호를 디지털 신호로 변환하여 검출되는 전력량과 설정된 기준 전력량을 비교하여, 가정 내의 전력 사용량이 지나치게 높은 경우 전원을 일시 차단하거나 경보를 발생시켜 안정적인 전력 수급을 도모하는 가정용 최대수요전력 감시 장치에 관한 것이다.The present invention relates to a device for monitoring and controlling the maximum demand power by household and household, and more specifically, by converting an analog signal input through a home electric meter into a digital signal and comparing the detected amount of power with a set reference power amount. In addition, the present invention relates to a maximum demand power monitoring device for homes that provides stable power supply by temporarily shutting off power or generating an alarm when power consumption in the home is excessively high.

최근 들어 냉방기기의 보급 확대로 매년 10% 이상 전력수요가 급증하고 있다. 그러나 위와 같은 전력수요의 증가에 비해 공급량은 제한되어 있으므로 전력 예비율의 절대 부족현상이 발생하여, 예기치 않은 전력공급의 중단사태가 종종 발생한다.In recent years, the demand for electricity has increased more than 10% due to the expansion of air conditioners. However, the supply is limited compared to the above increase in power demand, so the absolute shortage of power reserve occurs, and unexpected power supply interruption often occurs.

이에 따라, 전력공급업체에서는 최대수요전력의 증가를 억제하기 위해 전기요금 산정방식에 있어 시간대별, 계절별 차등요금제도를 적용하여 보다 다양화하고, 기본요금 산정의 최대수요전력의 하절기 냉방부하의 급증을 고려한 7월, 8월, 9월의 검침결과를 적용하며, 전력수요를 감소시키는 고객에게 소정의 지원금을 지급하는 부하관리제도를 도입하는 등, 하절기 냉방부하에 따른 피크부하의 분산을 위해 정책적인 해결방안을 제시하고 있다.Accordingly, in order to suppress the increase in the maximum demand power, the electricity supplier has diversified the application of the hourly and seasonal differential rate system in the electricity rate calculation method, and the increase in the cooling load in the summer of the maximum demand power of the basic rate calculation In order to distribute peak loads due to cooling loads in the summer, the metering results of July, August, and September are taken into consideration, and a load management system that pays a certain amount of subsidies to customers who reduce power demand is applied. It suggests a general solution.

그러나 이러한 정책적인 해결방안으로는 불시에 발생할 수 있는 순간적인 전력량의 급증에 따른 전력공급의 중단사태에는 대처할 수가 없으므로, 하절기에는 전력공급의 중단의 위험성을 늘 내포하게 된다. 또한, 일단 전력공급의 중단사태가 발생하면 복구 시까지 많은 시간과 비용이 소요되므로, 특히 전력공급의 필요성이 절대적으로 높은 하절기에는 많은 불편함을 초래하는 문제점이 있다.However, this policy solution cannot cope with the power supply interruption caused by the sudden increase in the amount of power that can occur at any time. Therefore, there is always a risk of power supply interruption in the summer. In addition, once a power supply interruption occurs, it takes a lot of time and money to recover, especially in the summer when the need for power supply is absolutely high, there is a problem that causes a lot of inconvenience.

아파트와 같은 공동주택이나 일반주택에는 가정에서 사용하는 직류 또는 교류의 전력이나 전력량을 측정하는 가정용 전기 검침기로써 전력량계가 설치된다. 상기 전력량계의 일종으로 최근 들어 많이 사용되는 전자식 전력량계는 아날로그 상태의 전압, 전류 신호를 디지털로 변환하여 컴퓨터로 전력을 계산하여 디지털로 표시한다.  In multi-unit houses such as apartments or general houses, electricity meters are installed as household electric meter reading devices that measure the power or amount of direct current or alternating current used at home. Electronic wattmeter, which has been used recently as a kind of wattmeter, converts voltage and current signals of analog state into digital and calculates power with a computer and displays it digitally.

그러나 이러한 종래의 전력량계는 단순하게 전력부하에서 소모되는 전력, 전력량, 역률 등을 표시하는 기능만 있고, 전력 소모에 따라 전력부하의 전원을 효율적으로 제어 관리하거나, 각각의 부하에 대한 개별적인 전원 관리 및 제어 기능이 없으므로, 단순 검침 이외에 설치에 따른 효율적인 이용이 이루어지지 못하는 문제점이 있다.However, such a conventional electricity meter has only a function of displaying power, amount of power, power factor, etc. consumed by the power load, and efficiently controls and manages the power of the power load according to the power consumption, or manages individual power for each load. Since there is no control function, there is a problem in that the efficient use according to the installation other than the simple meter reading is not made.

본 고안은 상기한 종래의 문제점을 해결하기 위한 것으로, 전기 검침을 위해 각 가구별로 설치된 가정용 전자식 전력량계를 이용하여, 전력을 검출함과 동시에 전력 사용량을 설정된 기준값과 비교하여 최대수요전력에 도달하는 경우 각각의 전력부하를 선택적으로 투입 또는 차단함으로써 전력부하를 효율적으로 제어 관리하는 최대수요전력 감시장치를 제안하는 것을 목적으로 한다. The present invention is to solve the above-described problems, when using the home electronic electricity meter installed for each household for the electric meter reading, when the power reaches the maximum demand by comparing the power consumption with the set reference value An object of the present invention is to propose a maximum demand power monitoring device that efficiently controls and manages a power load by selectively turning on or off each power load.

상기한 목적을 달성하기 위하여, 본 고안에 따른 가정용 최대수요전력 감시 장치는 가정용 검침기를 이용하여 최대수요전력을 감시하는 장치에 있어서,In order to achieve the above object, the maximum demand power home monitoring apparatus according to the present invention is a device for monitoring the maximum demand power using a household meter,

위와 같이 구성된 본 발명 최대수요전력 감시장치의 작용을 보다 상세하게 설명한다. The operation of the maximum demand power monitoring device of the present invention configured as described above will be described in more detail.

먼저, 전술한 바와 같이 감시 제어부(103)에는 특정 기준 전력값(피크치), 전력량값, 전력 부하의 사용에 따른 특정시간 등에 따른 제어순서가 미리 프로그래밍 된다. 이때 상기 특정 기준 전력값은 키처리부(104)를 통해 입력 및 설정 가능하다.First, as described above, the monitoring control unit 103 is preprogrammed with a control procedure according to a specific reference power value (peak value), a power amount value, a specific time according to the use of the power load, and the like. In this case, the specific reference power value may be input and set through the key processor 104.

이러한 상태에서, 신호 변환부(101)를 통해 아날로그 전원이 디지털 신호로 변환, 입력되면, 신호검출 및 연산부(102)에서는 상기 디지털 신호를 검출하여 전압, 전류, 주파수, 역률, 전력, 유무효 전력량 등의 연산 작업이 수행된다. In this state, when the analog power source is converted into a digital signal through the signal conversion unit 101 and inputted, the signal detection and calculation unit 102 detects the digital signal to detect voltage, current, frequency, power factor, power, and an effective amount of power. Computational operations are performed.

이에 따라 상기 감시 제어부(104)에서는 상기 연산작업 결과 검출된 전력값이 미리 설정된 특정 기준 전력값(피크치)에 도달하는 경우, 해당 부하에 대하여 제어펄스 신호를 송출하여, 전력차단 및 경보 발생부(107)를 통해 선택적으로 전력을 차단하고, 경보를 발생시킨다. 이때, 유무효 전력량 발생부(108)를 통해 각 부하들의 유무효 전력량에 관한 정보를 분석하고 그 결과를 펄스출력으로 발생시켜, 전력 사용자의 현재의 유무효 전력량 정보를 손쉽게 파악할 수 있도록 유도한다.Accordingly, when the power value detected as a result of the calculation operation reaches a predetermined reference power value (peak value), the monitoring control unit 104 sends a control pulse signal to the corresponding load, and the power cutoff and alarm generation unit ( 107) selectively shuts off power and generates an alarm. At this time, the information about the amount of effective power of each load through the effective amount of power generation unit 108 and generates the result as a pulse output, so that the current effective amount of power information of the power user can be easily identified.

예를 들어, 하절기와 같이 냉방부하에 대한 사용량이 급증하는 경우 냉방장치의 전력 사용량이 급증하여 설정된 기준값이 도달하게 되면, 일정 시간동안 냉방기에 공급되는 전력을 차단되도록 설정함으로써 일시적으로 냉방을 중단시켜 과부하로 인한 사고를 예방할 수 있게 되는 것이다. For example, when the amount of cooling load increases rapidly in summer, when the power consumption of the air conditioner increases and the set reference value is reached, the cooling is temporarily stopped by setting the power supply to the air conditioner to be cut off for a predetermined time. It is possible to prevent accidents caused by overload.

또한, 위와 같은 전력량 등의 각종 측정값 및 연산값은 정보 저장부(105)에 저장되며 표시부(106)를 통해 수시로 확인 가능하다.In addition, various measurement values and calculation values such as the amount of power as described above are stored in the information storage unit 105 and can be checked at any time through the display unit 106.

이러한 일력의 제어과정은 외부 통신부(109)를 통해 원격으로 제어 및 조회할 수 있으며, 외부 검침용 표시부(110)를 통해 외부에서도 확인 가능하므로 이를 전기 검침에 활용할 수도 있다.The control process of such a power can be remotely controlled and inquired through the external communication unit 109, and can also be used for electric meter reading because it can be checked from the outside through the external meter reading display unit 110.

본 고안은 상기한 실시예에 한정되지 않고, 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 분야에서 통상의 지식을 가지는 자라면 누구나 수정 및 변환 실시가 가능한 기술사상 역시 이하의 실용신안등록청구범위에 속하는 것으로 보아야 한다.The present invention is not limited to the above-described embodiment, anyone without ordinary skill in the field to which the present invention belongs without departing from the gist of the present invention, the technical idea that can be modified and converted also the utility model registration claims as follows Should be regarded as belonging to

상기한 구성의 본 고안에 따르면, 본 고안은 전기 검침을 위해 각 가구별로 설치된 가정용 전자식 전력량계를 이용하여, 전력을 검출함과 동시에 전력 사용량을 설정된 기준값과 비교하여 최대수요전력에 도달하는 경우 각각의 전력부하를 선택적으로 투입 또는 차단함으로써 각 가구별로 전력부하를 효율적으로 제어 관리할 수 있다.According to the present invention of the above-described configuration, the present invention uses a home electronic electricity meter installed for each household for the electric meter reading, when detecting the power and comparing the power consumption with the set reference value, the respective By selectively turning on or off the power load, it is possible to efficiently control and manage the power load for each household.
