Abstract

The present invention relates to an uninterruptible power system for electricity facilities of a large building. More particularly, the uninterruptible power system is, under normal circumstances, separately operated for a low-risk (greater than 100V and less than 700V) load facility and a high-risk (greater than 700V and less than 7,000V) load facility. Further, when the facilities are checked or repaired, or when legal inspection is performed, or when an accident occurs, integrated operation is enabled so that the uninterruptible power system supplies power in an uninterruptible power state without stopping the operations of the facilities within the building. Simultaneously, a customer electricity load facility is separately operated as an annual load facility or as a seasonal load facility, as an uninterruptible power load facility or as an interruptible power load facility, and as a low-risk load facility or as a high-risk load facility. Thus, the uninterruptible power system for electricity facilities may be flexibly used according to the power operations of the electricity load facilities and increases in facility capacity. According to the present invention, the customer electricity facility receiving the electricity transmitted or distributed from different substations and different distribution stations may, under normal circumstances, be separately operated as the low-risk load facility or the high-risk load facility. Further, when the facilities are checked or repaired, when legal inspection is performed, or when an accident occurs, integrated operation is enabled so that the uninterruptible power system may supply power in the uninterruptible power state without stopping the operations of the facilities within the building. Thus, economic harm due to a power interruption may be prevented.

Description

대형빌딩 전기설비 무정전시스템Large Building Electrical Equipment Uninterruptible System
본 발명은 대형빌딩 전기설비 무정전시스템에 관한 것으로, 보다 상세하게는 평상시에는 저위험(100V이상 700V이하) 부하설비와 고위험(700V이상 7,000V이하) 부하설비를 분리 운영하고, 설비의 점검, 정비, 법적 검사나 사고시에는 통합 운영이 가능하도록 건물 내 설비의 동작 정지없이 무정전 상태로 전력을 공급하며, 동시에 수용가의 전기부하설비를 연중부하설비와 절기부하설비 정전불가 부하설비와 정전가능 부하설비, 위험리스크가 적은 부하설비와 리스크가 큰 부하설비로 분리운영하며 전기부하설비에 전력 운영 및 설비용량 증감에 탄력적으로 수행할 수 있도록 하는 대형빌딩 전기설비 무정전시스템에 관한 것이다.The present invention relates to an uninterruptible system for large-scale building electrical equipment, and more specifically, to separate and operate a low-risk (100V or more and 700V or less) load facility and a high-risk (700V or more and 7,000V or less) load facility and inspect and maintain the facility. In case of legal inspection or accident, it provides uninterrupted power without stopping operation of facilities in the building so that it can be integrated and operated at the same time. The present invention relates to a large-scale uninterruptible electrical system for large-scale building electrical equipment, which is divided into a load facility having a low risk risk and a load facility having a high risk, and is able to flexibly perform power operation and capacity increase and decrease in the electric load facility.
전력공급계통은 전기공급사업자의 전력설비와 수용가의 전력설비로 구분할 수 있으며, 전기공급 사업자의 전력설비는 전력조류(power flow)제어기술, 초고압송전기술, 계통운용기술의 고도화로 공급신뢰도가 향상되었지만, 천재지면, 예측불허의 사고, 전력계통의 고장, 전력공급기의 고장/수리보수 등으로 인하여 무정전 전력공급이 매우 힘든 것으로 알려져 있다. The power supply system can be divided into the power equipment of the electricity supplier and the power equipment of the consumer, and the power equipment of the electricity supplier is improved in reliability by the advancement of power flow control technology, ultra-high voltage transmission technology, and system operation technology. However, because of the genius, unforeseen accidents, breakdown of the power system, breakdown / repair of the power supply, uninterruptible power supply is known to be very difficult.
반도체제조공장, 화학플랜트 등 첨단화된 대형사업장과 전산센터, 중요한 의료기기가 설치된 종합병원, 상수도 수전설비 등의 수용가 시설사업장에서는 무정전 전원공급을 요구하고 있다. 이러한 수용가 시설사업장에는 정전(blackout)에 대하여 자가 발전소를 운용하는 사업장도 있다.Advanced large-scale workplaces such as semiconductor manufacturing plants, chemical plants, computer centers, general hospitals with important medical devices, and consumer facilities such as water supply and faucet facilities require uninterrupted power supply. Some of these consumer facility sites also operate their own power plants against blackouts.
왜냐하면, 특정 대상의 중요 전기시설에서 정전으로 인한 피해는 천문학적인 경제적 손실과 인명의 살상을 야기할 수 있다. 수전방식의 신뢰성이 낮은 수전설비에서 정전발생으로 인한 피해를 최소화하기 위하여 종래에는 대용량의 무정전 전원장치(UPS: uninterruptible power supply), 비상발전기를 설치함으로써 수전설비의 대형화로 많은 공간이 필요로 하고 고비용의 투자비가 발생하는 등의 문제가 있었다. Because damage caused by power outages in critical electrical installations of certain targets can lead to astronomical economic losses and death. In order to minimize the damage caused by power failure in the low-reliability power receiving facilities of the power receiving system, a large capacity of the uninterruptible power supply (UPS) and an emergency generator is conventionally required, which requires a lot of space and high cost. There was a problem such as an investment cost.
현재 대다수의 수용가 전력설비는 전력회사에서 보내온 전기를 수용가의 건축물 안으로 받아들이는 설비를 수전설비(Power Receiving System)와, 수전전압을 수용가의 건축물에서 필요한 전압으로 바꾸는 변전설비 및 변전된 전압의 입력에 의해 동작되는 부하설비로 나누어진다.Currently, the majority of consumer power facilities are equipped with a power receiving system that receives electricity from the utility company into the customer's building, and a substation facility that converts the receiving voltage from the consumer's building to the required voltage. It is divided into load equipment operated by
위와 같은 수용가 전력설비 중 수전설비는 하나의 수용가에 하나가 설치 운영되는 것이 일반적이며, 수용가의 부하설비에 따라 운영되지 않고 있다. 예를 들면, 저위험부하설비와 고위험부하설비가 하나의 수전설비의 부하로 연결되어 있기 때문에 설비에 따라 부하가 적절하게 분산되지 아니하여 부하에 따라 전체가 정전되는 현상이 발생하기도 하는 등의 문제가 있었다.Among the above-mentioned consumer electric power facilities, the power receiving equipment is generally installed and operated in one customer, and is not operated according to the customer's load facility. For example, since the low risk load facility and the high risk load facility are connected to the load of one faucet facility, the load may not be properly distributed depending on the facility and the entire power failure may occur depending on the load. There was.
또한, 저위험 부하설비는 예를 들어 24시간 동안 필수적으로 동작하는 조명등과 같은 설비인데 비해 고위험 부하설비는 예를 들어 모터 등과 같이 필요에 의해 운용되는 설비들이며, 대개는 고위험 부하설비가 문제가 되어 정전이 발생하게 되며, 건축물 전체가 정전되는 사태로 번지기도 한다.In addition, low-risk load facilities are facilities such as lighting, which is mandatory for 24 hours, whereas high-risk load facilities are facilities that are operated as needed, such as motors. Power outages may occur, and the entire building may be blackouted.
그리고, 정전시 문제가 되는 부분은 수전설비가 대부분이므로 수전설비를 사전에 점검해야 하는데, 종래에는 부하설비에 전압을 공급하면서 적절하게 점검할 수가 없었다.In addition, since most of the power receiving facilities are a problem in the case of power failure, the power receiving facilities should be checked in advance, but in the past, it was not possible to properly check while supplying voltage to the load facilities.
왜냐하면, 점검시 수전설비 앞뒤로 전원을 차단하면 조명등과 같이 필수적인 부하설비가 정전되기 때문이다.This is because, when checking the power supply to the front and back of the faucet facility, essential load equipment such as a lamp is outage.

구체적으로 설명하자면, 전기부하설비(power load facilities)를 저위험 부하설비와 고위험 부하설비로 각각 분리하여 각각의 자동부하절체개폐기에 구성하게 된다.Specifically, power load facilities are divided into low risk load facilities and high risk load facilities, respectively, and configured in each automatic load transfer switch.
상기 제1자동부하절체개폐기(110)는 제1변배전소 및 제2변배전소로부터 송배전되는 전압 중 적어도 하나를 선택하여 저위험용 수전설비로 수전시키고, 수전되는 전압이 정전 시 스위칭되어 다른 변배전소로부터 송배전되는 전압을 저위험용 수전설비로 수전시키게 되며, 상기 제2자동부하절체개폐기(210)는 제1변배전소 및 제2변배전소로부터 송배전되는 전압 중 적어도 하나를 선택하여 고위험용 수전설비로 수전시키고, 수전되는 전압이 정전 시 스위칭되어 다른 변배전소로부터 송배전되는 전압을 고위험용 수전설비로 수전시키게 된다. The first automatic load switching switch 110 selects at least one of voltages transmitted and distributed from the first substation and the second substation and receives the low-risk power receiving facility, and the received voltage is switched at the time of power failure to switch to another substation. The voltage transmitted and received from the power supply to the low-risk faucet facility, the second automatic load switching switch 210 selects at least one of the voltage transmitted and distributed from the first substation and the second substation to the high-risk faucet facility. The power received and the received voltage is switched at the time of power failure to receive the voltage transmitted and distributed from other substations to the high-risk power receiving facility.
상기 제1자동부하절체개폐기(110) 및 제2자동부하절체개폐기(210)는 제1변배전소(100)와 제2변배전소(200)으로부터 각각 송/배전되는 전압을 제1포트(IP1)와 제2포트(IP2)로 분리하여 입력하게 된다.The first automatic load switchgear 110 and the second automatic load switchgear 210 respectively transmit / discharge voltages from the first substation 100 and the second substation 200 to the first port IP1. Input is separated into and second port (IP2).
또한, 제1변배전소 및 제2변배전소는 전기사업자가 다른 계통으로 운영하는 것으로 모두 동시에 정전되지 않는 것이어야 하며, 송배전전압은 154/22KV이다.In addition, the first substation and the second substation are operated by different utilities and should not be interrupted at the same time. The transmission and distribution voltage is 154 / 22KV.
상기 제1자동부하절체개폐기(110) 및 제2자동부하절체개폐기(210)의 공통단자(CP)는 제1차단기(120) 및 제2차단기(220)의 일차측에 각각 접속되어 있다.The common terminal CP of the first automatic load switching switch 110 and the second automatic load switching switch 210 is connected to the primary sides of the first circuit breaker 120 and the second circuit breaker 220, respectively.
또한, 상기 제1차단기(120) 및 제2차단기(220)의 이차측(출력측)에는 저위험용 수전설비(low power receiving facilities :LRPF)와 고위험용 수전설비(high power receiving facilities: HPRF)가 각각 접속되어 있다. In addition, low power receiving facilities (LRPF) and high power receiving facilities (HPRF) are provided on the secondary side (output side) of the first circuit breaker 120 and the second circuit breaker 220. Each is connected.
상기 저위험용 수전설비(130)와 고위험용 수전설비(230)는 각각 계기용 변압 변류기(MOF)를 각각 포함하여 구성된다.The low-risk faucet facility 130 and the high-risk faucet facility 230 is configured to include a transformer transformer current transformer (MOF), respectively.
상기 저위험용 수전설비와 고위험용 수전설비의 일차측 전압과 이차측 전압은 우리나라의 송배전전압과 전력수용가 필요로 하는 전력에 따라 설계될 수 있는 것으로 본 발명은 이에 한정되지 않는다. The primary side voltage and the secondary side voltage of the low-risk faucet and the high-risk faucet may be designed according to the power required by the power transmission and distribution voltage and the power reception of the present invention.
또한, 상기 저위험용 수전설비와 고위험용 수전설비의 출력측에는 제3차단기(140) 및 제4차단기(240)이 설치 구성되어 진다.In addition, a third circuit breaker 140 and a fourth circuit breaker 240 are installed on the output side of the low risk power receiver and the high risk power receiver.
상기와 같이 분리 운영하는 이유는 두 개의 변배전소 중 어느 하나에 문제가 발생하면 자동부하절체개폐기에서 바로 절체시켜 정전되는 불상사를 방지하기 위한 것이다.The reason for the separation operation as described above is to prevent an accidental power failure by switching directly from the automatic load transfer switch when a problem occurs in any one of the two substations.
또한, 저위험용 수전설비 및 고위험용 수전설비의 일차측과 2차측에 각각 차단기들을 설치 구성하는 이유는 일반적으로 수전설비가 고장이 잦으므로 설비의 점검, 정비, 법적 검사나 사고시에는 통합 운영이 가능하도록 특정 설비의 일차측 및 이차측을 차단한 후 점검 및 교체를 수행하게 되는 것이다.In addition, the reason why the breakers are installed on the primary side and the secondary side of the low-risk faucet facility and the high-risk faucet facility, respectively, is that the faucet facilities are frequently broken. If possible, the primary and secondary sides of a particular facility are shut off and then checked and replaced.
예를 들어, 설명하자면, 저위험용 수전설비를 점검하고자 할 경우에는 제1차단기 및 제3차단기가 동작되어 공급되는 전압을 차단시키게 된다.For example, if you want to check the low-risk faucet facility, the first circuit breaker and the third circuit breaker is operated to cut off the supply voltage.
이때, 저위험 부하설비는 항상 전압이 공급되어야 하므로 제2변압기로부터 변압된 전압을 타이개폐기(300)를 거쳐 제3변압기로 공급하게 되며, 제3변압기를 통해 변압된 낮은 전압이 저위험 부하설비에 공급되게 된다.At this time, since the low-risk load facility must always be supplied with voltage, the voltage transformed from the second transformer is supplied to the third transformer through the tie switch 300, and the low voltage transformed through the third transformer is low-risk load facility. To be supplied.
또한, 고위험 부하설비는 상기한 방법과 유사하게 제2차단기 및 제4차단기를 차단하고 고위험용 수전설비를 점검할 수 있으며, 이러한 경우에는 제1변압기에 의해 변압된 전압이 타이개폐기를 통해 고위험 부하설비에 공급되는 것이다.In addition, the high risk load facility may check the high risk faucet facility by shutting off the second breaker and the fourth breaker similarly to the above-described method, and in this case, the voltage transformed by the first transformer is passed through the tie breaker. It is supplied to the facility.
그러므로 본 발명에서는 부하설비에 전압을 공급한 채로 수전설비를 점검할 수 있다.Therefore, in the present invention, the power receiving facility can be checked while supplying voltage to the load facility.
종래의 경우에는 상기 저위험용 수전설비를 점검할 수도 없을 뿐더러 점검하고자 할 경우에는 모든 전압을 차단한 상태에서 수행해야 하므로 상당한 경제적 손실을 감수할 수 밖에 없었다.In the conventional case, it is not possible to check the low-risk faucet facility, and if it is to be checked, it must be carried out in a state where all voltages are cut off.
상기 타이개폐기(300)는 제5차단기 및 제6차단기의 출력측에 설치 구성하여 양측에 동일 전압이 공급될 경우에는 차단하고, 일측에 전압이 공급되지 않을 경우에 공급되지 않는 곳으로 전압을 공급시키게 된다.The tie breaker 300 is installed on the output side of the fifth circuit breaker and the sixth circuit breaker to cut off when the same voltage is supplied to both sides, to supply the voltage to the place that is not supplied when the voltage is not supplied to one side do.
즉, 제1변압기 및 제2변압기를 통해 25KV이하가 7KV이하로 변압되어 양측에 동일하게 전압이 부하설비로 공급되어 지는데, 특히 저위험 부하설비의 상측에는 제3변압기를 설치 구성하여 7KV보다 더 낮은 전압으로 변압시키게 된다.That is, 25KV or less is transformed to 7KV or less through the first transformer and the second transformer, and the voltage is supplied to the load equipment equally on both sides.In particular, the third transformer is installed on the upper side of the low-risk load equipment and is more than 7KV. It is transformed to low voltage.
결국, 제3변압기를 통해 700V이하로 전압이 변압되어 해당 전압을 저위험 부하설비에 공급하게 되는 것이다.As a result, the voltage is transformed to less than 700V through the third transformer to supply the voltage to the low-risk load facility.
또한, 상기 제1변압기 및 제2변압기의 출력측에는 제5차단기 및 제6차단기가 설치 구성되며, 제5차단기의 출력측에는 제3변압기를 설치 구성하여 더 낮은 전압으로 변압시키게 되고, 상기 제3변압기의 출력측에 제7차단기를 설치 구성하고 제7차단기의 출력측에 저위험 부하설비를 설치 구성하게 된다.In addition, a fifth circuit breaker and a sixth circuit breaker are installed at the output side of the first transformer and the second transformer, and a third transformer is installed at the output side of the fifth circuit breaker to transform the voltage to a lower voltage. The 7th circuit breaker is installed on the output side of the circuit breaker and the low risk load equipment is installed on the output side of the 7th circuit breaker.
그리고, 제6차단기의 출력측에는 고위험 부하설비를 설치 구성하게 되는 것이다.In addition, a high risk load facility is installed on the output side of the sixth circuit breaker.
상기한 바와 같이, 전압용 수전설비와 변압기 그리고, 부하설비들 사이에 각각 차단기를 설치 구성하는 이유는 설비 점검시 입력측 및 출력측을 차단하여 혹시 모를 사고에 대비하기 위한 것이다.As described above, the reason why the circuit breaker is installed between the power receiving facility, the transformer, and the load facilities is to prepare for an accident by blocking the input side and the output side during the facility inspection.
상기 제1변압기 및 제2변압기는 예를 들어, 25KV이하 전압을 7KV이하로 변압시키고, 제3변압기는 7KV이하를 700V이하로 변압시키게 되고, 제3변압기를 거친 700V가 저위험 부하설비에 공급되고, 제2변압기를 거친 7KV이하가 고위험 부하설비에 공급되는 구조를 가지게 된다.The first transformer and the second transformer, for example, to transform the voltage below 25KV to 7KV, the third transformer to transform 7KV or less to 700V or less, 700V passed through the third transformer is supplied to low-risk load equipment In addition, less than 7KV through the second transformer has a structure that is supplied to the high risk load facility.
또한, 상기와 같이 제1변배전소로부터 송배전되는 전압(전력)을 사용전원으로 입력하는 상태에서 제1변배전소가 정전되면, 제1자동부하절체개폐기와 제2자동부하절체개폐기는 입력포트를 제2포트(IP2)로 절체하여 제2변배전소로부터 송배전되는 예비전원을 저위험용 수전설비와 고위험용 수전설비로 수전시킨다. In addition, when the first substation is out of power while the voltage (power) transmitted from the first substation is input to the power source, the first automatic load switching switch and the second automatic load switching switch are configured to remove the input port. Transfer to 2 ports (IP2) and receive the reserve power from the second substation to the low-risk faucet facility and the high-risk faucet facility.
따라서, 도 1의 실시 예와 같이 다른 계통의 독립된 2개의 변배전소로부터 별도의 송배전되는 전력을 공급받아 이중 하나의 송배전된 전력을 상시전원으로 하여 저위험용 수전설비(LPRF)와 고위험용 수전설비(HPRF)로 수전시키는 본 발명의 분리운영시스템은 상시 전원이 정전되는 경우, 자동적으로 받고 있는 비정전상태를 유지하는 변배전소의 전력으로 자동으로 스위칭하여 전력을 공급함으로써 무정전상태로 전기부하설비를 가동시킬 수 있음을 알 수 있다. Accordingly, as shown in the embodiment of FIG. 1, low power faucet facilities (LPRF) and high risk faucet facilities are supplied with power that is separately transmitted and distributed from two independent substations of different systems, with one of the transmitted and distributed power sources being a constant power source. The separate operation system of the present invention which receives power by HPRF operates an electric load facility in an uninterruptible state by supplying power by automatically switching to the power of a substation that maintains an uninterrupted state, which is automatically received when the power is always off. It can be seen that.
또한, 본 발명의 경우에는 대형 호텔이나 병원 등과 같이 업종 특성상 24시간 영업을 수행하는 정전이 불가한 건물에 적용하여야 효과가 증대될 것이다.In addition, in the case of the present invention, the effect will be increased when applied to a building that can not operate power outages that are open 24 hours, such as large hotels or hospitals.
도 2는 저위험용 수전설비 및 고위험용 수전설비를 한 그룹으로 하여 다수의 그룹이 서로 연결될 경우에, 각 그룹간 타이개폐기들을 서로 연결시켜 병렬 운행이 가능한 예를 나타낸 예시도로서, 다수의 제1자동부하절체개폐기와 다수의 제2자동부하절체개폐기가 구성되고, 하측의 구성도 동일하게 다수가 구성되어 진다.FIG. 2 is an exemplary view illustrating an example in which a low risk power receiving facility and a high risk power receiving facility are connected to each other in a group, and in which a plurality of groups are connected to each other by connecting the tie breakers between the groups. One automatic load switchgear and a plurality of second automatic load switchgears are configured, and a plurality of lower load switchers are configured in the same way.
이때, 타이개폐기와 타이개폐기를 서로 연결시키게 되면 어느 한 곳에 문제가 발생하거나 점검시 동일한 전압이 공급되어 말단에 위치한 부하 설비는 항상 전압이 공급되게 된다.At this time, when the tie breaker and the tie breaker are connected to each other, a problem occurs in one place or the same voltage is supplied at the time of checking, so that the load equipment located at the end is always supplied with voltage.
