Description

송전·배전선로의 고장구간 자동개폐장치{Failure of power electric distribution lines between the automatic opening device}Failure of power electric distribution lines between the automatic opening device}

본 발명은 송전·배전선로의 고장구간 자동개폐장치에 관한 것으로서 보다 상세하게는 변대주를 지나는 송전선로 또는 배전선로의 선단측과 후단측에 설치된 센서수단의 검측신호에 의해 선로개폐장치가 작동하여 송전·배전선로의 고장시 송전·배전선로의 흐름을 일시 차단시키는 송전·배전선로의 고장구간 자동개폐장치에 관한 것이다.The present invention relates to an automatic opening and closing device of the failure section of the transmission and distribution line, and more specifically, the line opening and closing device is operated by the detection signal of the sensor means installed on the front end and the rear end of the transmission line or the distribution line passing through the perimeter. The present invention relates to an automatic switching device for a fault section of a transmission / distribution line that temporarily shuts off the flow of the transmission / distribution line when the transmission / distribution line breaks down.

널리 알려진 바와 같이, 변전소로부터 수용가로 전력을 공급하는 송전·배전선로는 수많은 수용가에 각각 전력을 공급해야 하기 때문에 그 구성은 복잡한 간선 및 지선들로 이루어진다. 따라서, 송전·배전선로 상에 지락(전선이 끊어져 땅에 붙어 접지되는 경우) 또는 단락(서로 다른 상의 전선들이 붙는 경우) 사고가 발생하여 고장 전류 및 전압이 발생하는 경우, 그 사고가 발생한 고장점의 위치를 찾기 위해서는 많은 노력이 필요하게 된다.As is well known, the transmission and distribution lines that supply power from substations to customers are required to supply power to numerous customers, respectively, and the configuration is composed of complicated trunk lines and branch lines. Therefore, when a ground fault (when the wire is broken and grounded) or a short circuit (when the wires of different phases are stuck) occurs on the transmission / distribution line and a fault current and voltage occur, It takes a lot of effort to find the location of.

종래에는 송전·배전선로에 고장 전류 및 전압이 발생하는 경우, 고장 전류와 전압이 발생한 고장점을 찾기 위하여 변전소 차단장치를 동작시켜 가면서 현장의 조작자와 변전소 관리자가 주로 통신 수단을 이용하여 사고 지점에 관한 정보를 서로 교환함으로써 고장점을 찾는 것이 보편화된 방법이었다.Conventionally, when a fault current or voltage occurs in a transmission / distribution line, a substation breaker is operated to find a fault point where the fault current and voltage have occurred. Finding failure points by exchanging information about each other has been a common practice.

그러나, 상기와 같은 방법의 경우 많은 시간과 인력이 소모되며 복구 시간이 길어짐에 따라 정전 시간이 길어져, 전력 소비자의 큰 불편을 초래하는 문제가 빈번하게 발생하였다. However, in the case of the above method, a lot of time and manpower is consumed, and as the recovery time is long, the power failure time is prolonged, which causes a lot of inconveniences for power consumers.

이에 따라, 송전·배전선로의 사고 발생시 그 고장점의 위치를 신속히 파악하고 복구하여 정전 시간을 단축함으로써 전력 공급의 신뢰성과 수용가에 대한 서비스의 질을 향상시킬 수 있는 방법이 요구되어 왔다.Accordingly, there has been a demand for a method of improving the reliability of the power supply and the quality of service to the customer by quickly identifying and restoring the location of the failure point and reducing the power failure time in the event of an accident of the transmission and distribution lines.

그리하여 현재에는 변전계통에서, 부하용량 4000[kVA] 이하의 분기점 또는 수용가인입구에 선로 자동개폐기가 설치되어 있다. 상기 선로 자동개폐기는 지락사고가 발생하는 경우, 변전소의 차단기와 송전·배전선로에 설치된 선로개폐 제어장치와 협조하여 고장 구간만을 신속, 정확하게 차단 혹은 개방하여 고장 구간의 확대를 방지하고 그 피해를 최소화한다.Thus, in current substation systems, automatic switchgears are installed at branch points or customer entrances with a load capacity of 4000 [kVA] or less. In case of a ground fault, the automatic line breaker cooperates with the circuit breaker of the substation and the line open / close control device installed on the transmission / distribution line to quickly and accurately block or open only the fault section to prevent the expansion of the fault section and minimize the damage. do.

상기와 같이, 송전·배전선로에 사고가 발생하여 고장 전류와 전압이 감지되는 경우, 상기 고장 전류와 전압이 발생한 고장점을 분리하여 차단시키는 장치로는 차단기, 개폐기, 리클로저가 있다. 이하, 그 기능에 대하여 약술하기로 한다.As described above, when an error occurs in a transmission / distribution line and a fault current and a voltage are sensed, a circuit breaker, a switchgear, and a recloser are provided to separate and break a fault point at which the fault current and voltage are generated. Hereinafter, the function will be outlined.

차단기(Circuit Breaker, CB)는 송전선로로부터 매우 큰 크기의 고장 전류가 감지될 때 선로를 개방(Open) 또는 폐로(Close)할 수 있다. 또한, 필요에 따라 정상 전류가 흐르는 평소에도 선로를 개폐할 수도 있다.The circuit breaker (CB) may open or close the line when a very large fault current is detected from the transmission line. In addition, if necessary, the line can be opened and closed even in the normal current flow.

개폐기(Load Break Switch, LBS)는 차단기와는 달리, 전류가 흐르지 않거나 정상 전류와 전압이 흐를 경우에만 선로 개폐가 가능하고, 고장 전류와 전압이 발생하는 경우에는 선로 개폐를 할 수 없는 장치를 의미한다. 개폐기에는 그 동작제어를 위하여 FRTU(Feeder Remote Terminal Unit)라고 불리는 일종의 제어부를 설치할 수 있다. 즉, FRTU는 개폐기의 기계 장치부와 연결되어 개폐기의 선로 개폐를 제어하는 장치이다. 단, FRTU는 개폐기를 통한 선로 개폐를 스스로 판단하여 매커니즘을 제어하는 것이 아니고, 통신 기능을 통해 호스트(주제어장치)로부터 명령을 받아서 메커니즘을 제어할 수 있다.Unlike breakers, Load Break Switch (LBS) means a device that can be opened and closed only when no current flows or normal current and voltage flow, and a circuit cannot be opened or closed when a fault current and voltage occur. do. The switch may be provided with a kind of control unit called a Feeder Remote Terminal Unit (FRTU) for its operation control. In other words, FRTU is connected to the mechanical unit of the switchgear is a device for controlling the opening and closing of the line of the switchgear. However, FRTU does not control the mechanism by judging the opening and closing of the line through the switch, and can control the mechanism by receiving a command from the host (main control device) through the communication function.

리클로저(Recloser)는 선로의 재폐로를 수행하는 특수한 형태의 차단기이다. 배전선로로부터 고장 전류가 감지되고 일정 범위 이상 지속되면 리클로저는 선로를 개방하고, 미리 설정된 일정 시간이 지난 후에 선로를 다시 폐로한다. 선로 폐로후에도 고장 전류가 계속 감지되면, 리클로저는 상기와 같은 선로의 재폐로 과정을 미리 설정된 회수만큼 반복하고, 그 후에도 고장 전류가 지속되면 선로를 완전히 개방시키고 더 이상 재폐로 동작을 수행하지 않는다.Recloser is a special type of breaker that recloses the track. If a fault current is detected from the power distribution line and continues for a certain range, the recloser opens the line and closes the line again after a predetermined time. If the fault current is still detected after the line is closed, the recloser repeats the above line reclose process for a predetermined number of times, and if the fault current continues after that, the line is completely opened and no further reclose operation is performed. .

그런데 송전·배전선로에서 선로고장이 발생하였을 때 송전·배전관리시스템 또는 운영실 담당자의 판단에 의거하거나, 또는 송전·배전선로 고장구간 자동분리 프로그램에 의거 해당 선로의 개폐기 2대를 OFF하고, 연계된 타 선로의 개폐기를 투입하는 작업을 하게 된다.However, when a line breakdown occurs in a transmission / distribution line, the switch is turned off at the discretion of the transmission / distribution management system or the person in charge of the operation room, or according to the automatic separation program of the failure section of the transmission / distribution line. It is to work to put the switchgear of other line.

따라서 송전 배전관리시스템 또는 송전운영실의 담당자의 고장구간 판단 시간이 불가피한 실정이다. 시뮬레이션에 의한 교육의 부족과 사고라는 것은 상시 일어나는 것이 아니므로 인간은 고장 구간의 판단 오류 즉, 휴먼 에러에 의한 고장구간 분리시간을 지연시키는 경우도 있다.Therefore, it is inevitable that the fault section judgment time of the person in charge of the power transmission distribution management system or power transmission operation room is inevitable. Lack of education and accidents by simulation do not happen all the time, so humans sometimes delay the separation time of failure section by human error.

이러한 종래 문제점을 감안하여 근래에는 부하단의 전압과 전류를 검출하여 고장 전류 연산에 의한 고장점(FI : Fault Indicator)을 실시간으로 판단하여 상위 시스템(System)으로 전송한 후, 송전 자동화 알고리즘(Algorithm)에 의한 수행 명령이 단말장치에 전달되면 단말장치는 자체 통신 및 고장 판단 알고리즘으로 고장 구간을 분리/복귀하는 역할을 수행하는 송전·배전계통의 자동화 개폐기 즉, 송전·배전선로의 고장구간 자동개폐장치가 설치되어 사용되고 있다.In consideration of such a conventional problem, in recent years, the voltage and current of the load stage are detected, the fault point (FI: Fault Indicator) by calculating the fault current is determined in real time, transmitted to the upper system, and then the transmission automation algorithm (Algorithm) When the command is transmitted to the terminal device, the terminal device automatically switches the failure section of the transmission / distribution line, that is, the automatic switchgear of the transmission / distribution system that serves to separate / return the failure section by its own communication and failure determination algorithm. The device is installed and used.

It is to provide automatic switchgear of failure section of power transmission and distribution line which has the advantage of quickly separating / returning fault section because power is always supplied.
