본 발명은 배전 제어 자동화 시스템에 관한 것으로, 특히 원방에서 통신을 이용하여 배전 제어 단말장치의 동작치 설정이 가능한 배전 제어 자동화 시스템에 관한 것이다.The present invention relates to a distribution control automation system, and more particularly, to a distribution control automation system capable of setting an operation value of a distribution control terminal device using communication in a remote location.

제1도는 배전 제어 시스템의 구성을 개략적으로 나타낸 도이고, 제2도는 제1도의 상세 블럭도로서, 이러한 배전 제어 시스템은 배전제어 단말부(140)를 배전선에 설치한 후 통신을 통해 중앙제어부(100)에서 배전 계통의 사고와 계통 정보를 원방에서 감시하며, 사고 복구를 위해 개폐기(130)를 제어하는 기능등을 가지는 시스템을 말한다.FIG. 1 is a diagram schematically showing the configuration of a power distribution control system, and FIG. 2 is a detailed block diagram of FIG. 1. The power distribution control system installs a power distribution control terminal unit 140 on a power distribution line and communicates with the central controller through communication. In 100), the accident and system information of the power distribution system to monitor from afar, and refers to a system having a function such as controlling the switch 130 to recover the accident.

만약 배전선로에서 고장이 발생하면 큰 고장전류가 흐르게 되고, 이러한 고장전류는 개폐기(130)의 제어와 감시를 위한 배전제어 단말부(140)의 계측부(141)에서 계측하게 되고, 그 배전제어 단말부(140)의 전면에 위치한 동작치 설정 스위치(144)에 의해 설정되는 동작 파형과 동작 전류값을 기준으로 고장 판단부(142)에서 고장을 판단하게 된다.If a fault occurs in the distribution line, a large fault current flows, and the fault current is measured by the measurement unit 141 of the distribution control terminal unit 140 for the control and monitoring of the switch 130 and the distribution control terminal. The failure determination unit 142 determines the failure based on the operation waveform and the operation current value set by the operation value setting switch 144 located in front of the unit 140.

이러한 설정이 제대로 되었다면 제1도에 도시된 바와같이 3번째 배전제어 단말부까지는 고장을 판단하고, 4번째 배전제어 단말부는 고장전류가 흐르지 않으므로 고장을 감지하지 않는다.If such a setting is made correctly, as shown in FIG. 1, the third power distribution control terminal unit determines a failure, and the fourth distribution control terminal unit does not detect a failure since no fault current flows.

이와같은 고장 상황을 배전제어 단말부(140)가 중앙제어부(100)의 요구가 있는 경우 데이타 송수신(143)에 의해 변전소 통신부(111)를 통하여 상기 중앙제어부(100)로 전송하게 된다.When the distribution control terminal unit 140 requests the central control unit 100, the failure situation is transmitted to the central control unit 100 through the substation communication unit 111 by the data transmission / reception 143.

상기 배전제어 단말부(140)의 설정값은 설치된 위치의 부하에 맞도록 설정되어야 하며, 계통 구성이 변경되어 부하의 크기가 많이 변한 경우에는 새로운 동작 설정이 이루어지지 않으면 고장이 발생한 경우에 상기 각 배전제어 단말부(140)는 고장을 정확히 판단하지 못하게 된다.The setting value of the power distribution control terminal 140 should be set to match the load of the installed position, and if the system configuration is changed and the size of the load is changed a lot, the new operation setting is not made. The distribution control terminal unit 140 may not accurately determine the failure.

제3도는 이러한 배전선로의 고장처리 방식을 나타낸 도로서, 이에 도시된 바와같이, 배전선 #1에 사고가 발생하면 정전복구를 위해 배전선 #2에서 부하 A를 떠맡아야 된다.3 is a diagram illustrating a failure handling method of such a distribution line. As shown in FIG. 3, when an accident occurs in the distribution line # 1, the load A should be taken from the distribution line # 2 for power failure recovery.

따라서, 중앙제어부(100)는 송수신부(101)를 통해 수신되는 고장신호에 대한 처리 데이타를 데이타베이스(102)에서 읽어들여 고장처리부(103)에 의해 적절한 개폐기(130)를 선정하여 변전소 통신부(110)를 통해 배전제어 단말부(140)로 제어명령을 전송하며, 상기 배전제어 단말부(140)는 이 명령을 수신하여 개폐기(130)를 제어한다.Therefore, the central control unit 100 reads the processing data for the failure signal received through the transmission and reception unit 101 from the database 102 and selects the appropriate switch 130 by the failure processing unit 103 to perform the substation communication unit ( The control command is transmitted to the power distribution control terminal 140 through the 110, and the power distribution control terminal 140 receives the command to control the switch 130.

그러면, 선로구성이 바뀌게 되고, 변경된 배전 계통 구성에 따른 배전제어 단말부(140)의 동작치 설정이 필요하게 되며, 배전 운전원이 이 값을 변경하기 위하여 동작치를 계산하게 된다.Then, the line configuration is changed, it is necessary to set the operation value of the power distribution control terminal unit 140 according to the changed power distribution system configuration, the distribution operator calculates the operation value to change this value.

동작치가 계산되면 배전 운전원은 현장으로 출동하여 배전제어 단말부(140)의 전면에 설치된 동작치 설정 스위치(144)를 조작함으로써 동작치를 설정하면 배전선 #1에서 앞으로의 사고에 적절히 동작하게 된다.When the operation value is calculated, the distribution operator sets out the operation value by operating the operation value setting switch 144 installed in the front of the distribution control terminal unit 140 when the operation site is operated properly in the future accident in the distribution line # 1.

그러나, 이러한 배전제어 시스템에서는 동작치의 설정이 필요한 경우 배전 운전원이 현장에 출동하여 배전제어 단말장치의 동작치 설정 스위치를 통해서만 가능하게 되고, 원방에서는 동작치 설정이 불가능하여 넓은 장소에 분포되어 설치된 배전제어 단말장치의 계통 구성의 변화가 있을때마다 동작치 설정을 변경하기 위해서는 많은 시간과 노력이 필요하며, 실제 배전 자동화를 수행함에 있어서 많은 제약이 따르는 문제점이 있었다.However, in such a distribution control system, when an operation value needs to be set, the distribution operator is dispatched to the site and enabled only through the operation value setting switch of the distribution control terminal device. Whenever there is a change in the system configuration of the control terminal device, it takes a lot of time and effort to change the operation value setting, there is a problem that a lot of restrictions in performing the actual distribution automation.

따라서, 본 발명은 이러한 문제점을 감안하여 배전선의 계통 구성이 변경되면 원방의 중앙제어장치에서 동작치 계산을 수행하고, 그 정보를 변전소 통신장치를 통해 해당 배전제어 단말장치로 전송하여 동작치 설정이 원방에서 가능하도록 하는데 목적이 있는 것으로, 이와같은 목적을 갖는 본 발명을 상세히 설명한다.Therefore, in view of the above problem, the present invention performs calculation of operation value in the remote central control unit when the system configuration of the distribution line is changed, and transmits the information to the distribution control terminal device through the substation communication device to set the operation value. It aims at making it possible at a distance, and it demonstrates this invention which has such an objective in detail.

이와같이 이루어진 본 발명의 작용 및 효과를 제4도 및 제5도를 참조하여 상세히 설명한다.The operation and effect of the present invention thus made will be described in detail with reference to FIGS. 4 and 5. FIG.

배전선의 고장등으로 인하여 배전선상의 계통 구성이 변경되면 중앙제어부(200)의 동작치 설정부(205) 내부의 동작치 판단부에서 동작치의 재설정 여부를 판단하는데, 만약 변경해야 한다면 동작치 계산부에서 동작치 재설정을 위한 계산을 수행한 다음 그 설정값을 송수신부(201)를 통해 배전제어 단말부(220)로 전송하게 되며, 상기 배전제어 단말부(220)는 이를 데이타 송수신부(223)를 통해 입력받은 다음 동작치 저장 메모리(224)에 저장하게 된다.When the system configuration on the distribution line is changed due to a failure of the distribution line, the operation value determination unit inside the operation value setting unit 205 of the central control unit 200 determines whether to reset the operation value. After performing calculation for resetting the operation value, the setting value is transmitted to the power distribution control terminal 220 through the transceiver 201, and the power distribution control terminal 220 transmits the data transmission / reception unit 223. The next operation value received through the data is stored in the storage memory 224.

이후, 상기 중앙 제어부(200)는 동작치 설정값을 전송하고 그 전송된 동작치와 배전제어 단말부(220)에서 재전송된 값을 동작치 확인부에서 동일한 값인지를 확인한 다음 각 배전제어 단말부(220)의 고장판단의 동기화를 위해 해당 배전 단말부(220)에 고장판단 개시 명령을 전송하게 된다.Thereafter, the central control unit 200 transmits an operation value setting value and checks whether the operation value and the value retransmitted by the distribution control terminal 220 are the same value in the operation value checking unit, and then each distribution control terminal unit. In order to synchronize the failure determination of 220, the failure determination start command is transmitted to the distribution terminal 220.

또한, 상기 배전제어 단말부(220)의 동작치 저장 메모리(224)에 저장된 설정값이 맞는값인지를 확인하기 위해 중앙제어부(200)의 동작치 확인부에서 일정시간 간격으로 배전제어 단말부(220)의 저장된 값의 확인 작업을 수행하게 된다.In addition, in order to check whether the setting values stored in the operation value storage memory 224 of the power distribution control terminal unit 220 are correct values, the power distribution control terminal unit at regular intervals in the operation value checking unit of the central control unit 200 ( The operation of checking the stored value of 220 is performed.
