Description

계량 방식 판단 장치Weighing method judgment device

본 발명은 전력량계의 계량 방식 판단 장치에 관한 것이다. The present invention relates to an apparatus for determining a metering method of a wattmeter.

전력량계 펌웨어는 순방향 방식과 벡터 방식으로 전력 계량 값을 처리할 수 있다. The electricity meter firmware can process the power meter values in a forward and vector manner.

순방향 방식은 전기 판매 사업자가 전력을 생산하여 고객이 수전하는 전력과 고객이 전력을 생산하여 전기 판매 사업자로 역송하는 전력이 있는 경우, 고객이 전기 판매 사업자로 역송하는 전력을 계량하지 않고, 고객이 수전하는 전력만을 누적하는 계량 방식이다. 벡터 방식은 전기 판매 사업자가 전력을 생산하여 고객이 수전하는 전력과 고객이 전력을 생산하여 전기 판매 사업자로 역송하는 전력이 있는 경우, 상별로 벡터 계산을 통하여 상호 가감하여 수전 또는 송전하는 전력을 누적하는 계량 방식이다. The forward method does not measure the power returned by the customer to the electricity supplier if the electricity supplier generates electricity and receives power from the customer and the power is generated and returned to the electricity supplier. Receiving is a metering method that accumulates only the power. Vector method accumulates electricity received or transmitted by adding and subtracting each other through vector calculation for each phase when electricity sales company produces electricity and electricity received by customer and electricity returned by electricity sales company. It is a metering method.

순방향 방식과 벡터 방식은 전력을 전기 판매 사업자로부터 고객이 단방향으로 송전받는 경우에는 계량값이 동일하다. 다만, 고객이 발전을 하는 경우 전력 조류가 발생되어, 특정 상에서는 송전이 이루어지고, 나머지 상에서는 역송이 이루어지게 되어 양 방식의 계량값이 차이가 나게 된다.The forward and vector methods have the same weighing value when the customer is unidirectionally transmitting power from the electricity supplier. However, when the customer generates electricity, power current is generated, power transmission is performed in a specific phase, and reverse transmission is performed in the remaining phases, so that the weighing values of both methods are different.

정확한 전력 계량값 산출을 위하여는 전력량계가 순방향 방식과 벡터 방식 중 어떤 방식으로 전력을 계량하는 지를 파악하는 것이 필요하다. 다만, 전력 계량 방식은 소프트웨어적으로 선택될 수 있으므로, 전력량계의 외관/외형에 의해 구분되기 어려운 문제가 있다. For accurate power meter calculations, it is necessary to know whether the meter is metering power in a forward or vector manner. However, since the power metering method can be selected in software, there is a problem that it is difficult to distinguish by the appearance / appearance of the electricity meter.

종래, 실험실 환경에서 부하를 인가하고, 부하에 인가된 전력량과 계량값이 적산되는 양을 비교하여 전력량계에 적용된 전력 계량 방식을 판단하였다. 다만, 실험실 환경으로의 전력량계를 도입하기 위하여, 전력량계를 철거시, 부하 정전 등의 다수의 제반 문제가 발생되는 문제가 있다. Conventionally, the load is applied in a laboratory environment, and the power metering method applied to the electricity meter is determined by comparing the amount of power applied to the load and the amount accumulated in the meter. However, in order to introduce a wattmeter into a laboratory environment, when dismantling the wattmeter, a number of problems such as a load power failure occur.

본 발명의 과제는 부하 정전 없이 고객의 전력량계의 계량 방식을 판단할 수 있는 계량 방식 판단 장치를 제공하는 것이다. An object of the present invention is to provide a weighing method determination device that can determine the metering method of the customer's electricity meter without a load outage.

본 발명의 일 실시예에 따른 계량 방식 판단 장치는 피검사 대상에 해당하는 전력량계의 전력량을 제1 계량 방식으로 계량하는 제1 계량 모듈; 상기 전력량계의 전력량을 상기 제1 계량 방식과 다른 제2 계량 방식으로 계량하는 제2 계량 모듈; 및 상기 전력량계에서 계량된 전력량과 상기 제1, 2 계량 모듈에서 계량된 전력량을 비교하여, 상기 전력량계의 계량 방식을 판단하는 연산 처리부; 를 포함할 수 있다. Weighing method determination apparatus according to an embodiment of the present invention includes a first metering module for metering the amount of power of the electricity meter corresponding to the inspection target by the first metering method; A second metering module that measures the amount of power of the electricity meter in a second metering manner different from the first metering method; And an arithmetic processor configured to compare the amount of electricity metered in the electricity meter and the amount of electricity metered in the first and second metering modules to determine a metering method of the meter. It may include.

일 예로, 상기 제1 계량 방식 및 상기 제2 계량 방식 중 하나는 순방향 방식에 해당하고, 다른 하나는 벡터 방식에 해당할 수 있다. For example, one of the first metering method and the second metering method may correspond to a forward method, and the other may correspond to a vector method.

일 예로, 상기 연산 처리부는, 상기 전력량계에서 단위 시간 동안 계량된 전력량과 상기 제1, 2 계량 모듈에서 단위 시간 동안 계량된 전력량을 비교할 수 있다. For example, the operation processor may compare the amount of power metered in the unit meter for the unit time with the amount of power metered in the unit of time in the first and second metering modules.

일 예로, 상기 연산 처리부는, 상기 제1 계량 모듈에서 계량된 전력량과 상기 전력량계에서 계량된 전력량이 일치하는 경우, 상기 전력량계는 상기 제1 계량 방식이 적용된 것으로 판단하고, 상기 제2 계량 모듈에서 계량된 전력량과 상기 전력량계에서 계량된 전력량이 일치하는 경우, 상기 전력량계는 상기 제2 계량 방식이 적용된 것으로 판단할 수 있다. For example, when the amount of power metered in the first metering module and the amount of power metered in the meter are the same, the calculation processor determines that the first metering method is applied, and the meter is measured in the second metering module. When the amount of power measured and the amount of power metered in the meter are equal, the meter may determine that the second metering method is applied.

일 예로, 상기 연산 처리부는, 상기 전력량계에서 계량된 전력량을 유선 및 무선 중 적어도 하나의 통신 방식을 통해 수신할 수 있다. For example, the operation processor may receive the amount of power measured by the electricity meter through at least one communication scheme of wired and wireless.

일 예로, 상기 전력량계에 입력되는 전압은 병렬로 추출되어, 상기 제1 계량 모듈 및 상기 제2 계량 모듈에 제공될 수 있다. For example, the voltage input to the electricity meter may be extracted in parallel and provided to the first and second metering modules.

일 예로, 상기 전력량계에 입력되는 전류는 후크 온 방식 및 클램프 온 방식 중 하나의 방식으로 추출되어, 상기 제1 계량 모듈 및 상기 제2 계량 모듈에 제공될 수 있다.For example, the current input to the electricity meter may be extracted in one of hook-on and clamp-on methods and provided to the first and second metering modules.

일 예로, 상기 연산 처리부의 처리 결과를 출력하는 디스플레이부; 를 더 포함할 수 있다. For example, the display unit for outputting the processing result of the operation processor; It may further include.

본 발명의 일 실시예에 따르면, 부하 정전 없이 고객의 전력량계의 계량 방식을 판단할 수 있다. According to one embodiment of the present invention, it is possible to determine the metering method of the customer's watt-hour meter without load interruption.

또한, 단위 시간 동안 계량 모듈에서 계량된 전력량과 단위 시간 동안 고객의 전력량계에서 계량된 전력량을 비교하여, 고객의 전력량계의 계량 방식을 판단할 수 있을 뿐만 아니라, 단위 시간 오차도 확인할 수 있고, 이로써, 오결선 및 고객의 전력량계의 고장 또한 검출할 수 있다. In addition, by comparing the amount of electricity metered in the weighing module during the unit time and the amount of electricity metered in the customer's electricity meter during the unit time, not only can determine the metering method of the customer's electricity meter, but also can determine the unit time error, thereby, Incorrect wiring and faults in the customer's electricity meter can also be detected.

제1 계량 모듈(110) 및 제2 계량 모듈(120)은 서로 다른 방식으로 피검사 대상에 해당하는 고객의 전력량계의 전력량을 계량할 수 있다. 일 예로, 제1 계량 모듈(110)은 제1 계량 방식으로 전력량을 계량할 수 있고, 제2 계량 모듈(120)은 제2 계량 방식으로 전력량을 계량할 수 있다. The first metering module 110 and the second metering module 120 may measure the amount of power of the electricity meter of the customer corresponding to the inspection target in different ways. For example, the first metering module 110 may measure the amount of power in a first metering manner, and the second metering module 120 may meter the amount of power in a second metering manner.

제1 계량 모듈(110) 및 제2 계량 모듈(120) 중 하나는 순방향 방식으로 고객의 전력량계의 전력량을 계량하고, 다른 하나는 벡터 방식으로 고객의 전력량계의 전력량을 계량할 수 있다. One of the first metering module 110 and the second metering module 120 may measure the amount of power of the customer's electricity meter in a forward manner, and the other may measure the amount of electricity of the customer's electricity meter in a vector manner.

순방향 방식은 전기 판매 사업자가 전력을 생산하여 고객이 수전하는 전력과 고객이 전력을 생산하여 전기 판매 사업자로 역송하는 전력이 있는 경우, 고객이 전기 판매 사업자로 역송하는 전력을 계량하지 않고, 고객이 수전하는 전력만을 누적하는 계량 방식이다.The forward method does not measure the power returned by the customer to the electricity supplier if the electricity supplier generates electricity and receives power from the customer and the power is generated and returned to the electricity supplier.

제1 계량 모듈(110) 및 제2 계량 모듈(120) 각각은 고객의 전력량계에 입력되는 전압 및 전류를 이용하여 제1 계량 모듈(110) 및 제2 계량 모듈(120) 각각에 적용된 방식에 따라 고객의 전력량계의 전력량을 계량할 수 있다. Each of the first weighing module 110 and the second weighing module 120 is applied to each of the first weighing module 110 and the second weighing module 120 using a voltage and a current input to the customer's electricity meter. You can measure the power of your electricity meter.
