1: IED, 2: HMI 플랫폼,1: IED, 2: HMI platform,

본 발명은 변전소 모니터링 시스템에 관한 것으로서, 특히 변전소에 설치된 IED의 작동상태 정보를 상위시스템에서 효율적으로 모니터링하여 감시, 제어할 수 있도록 한 변전소 모니터링 시스템에 관한 것이다.The present invention relates to a substation monitoring system, and more particularly, to a substation monitoring system capable of efficiently monitoring, monitoring, and controlling operating state information of an IED installed in a substation in a higher system.

변전소는 GIS(가스절연차단기)나 변압기와 같은 전기설비 이외에도 센서, IED(Intelligeny Electronic Device) 그리고 상위 디스플레이 시스템 등으로 구성된다.Substations consist of sensors, intelligent electronic devices (IEDs) and higher-level display systems, as well as electrical installations such as GIS and gas transformers.

많은 센서로부터 계측된 전기설비의 입출력 정보를 근간으로 IED는 전기설비의 보호와 제어를 담당하고 운영자에게 필요한 중요정보를 표준 프로토콜에 맞춰 상위시스템으로 전송하게 된다.Based on the input and output information of the electrical equipment measured from many sensors, the IED is responsible for the protection and control of the electrical equipment and transmits important information required by the operator to the upper system in accordance with the standard protocol.

이렇게 전송된 정보는 운영자가 쉽게 인지할 수 있도록 상위 HMI(Human-Machine Interface: 디스플레이 시스템)에 표시하게 된다.This information is then displayed on the upper Human-Machine Interface (HMI) for easy operator recognition.

한 변전소 내에서는 다양한 회사의 IED 제품이 설치될 수 있으며 상위 시스템들과 이들 간의 통신은 동일한 통신 프로토콜을 이용하게 된다.Within a substation, IED products from various companies can be installed, and the upper systems and the communication between them use the same communication protocol.

현재 DNP 3.0(Distributed Network Protocol)이나 MODBUS 등을 많이 사용하며 향후 변전소 자동화 분야의 국제적 표준 프로토콜인 IEC 61850이널리 사용될 예정이다.Currently, DNP 3.0 (Distributed Network Protocol) and MODBUS are widely used, and IEC 61850, an international standard protocol for substation automation, will be widely used in the future.

도 1 은 종래 디지탈 변전소 시스템을 도시한 것으로서,1 illustrates a conventional digital substation system,

변전소에는 단로기, 차단기, 변압기와 같은 각종 현장기기가 설치되어 있고, 요소요소에는 IED가 설치되어 각종 현장기기의 작동상태정보 및 경보정보를 수집하여 상위시스템인 HMI, SNTP Server, Engineering Server 등으로 수집된 정보를 제공하도록 구성되어 있다.Substations are equipped with various field devices such as disconnectors, breakers, and transformers, and IEDs are installed in the element elements to collect operating status information and alarm information of various field devices and collect them to higher-level systems such as HMI, SNTP Server, and Engineering Server. It is configured to provide the information.

이러한 변전소에 설치되는 변전소 모니터링 시스템은 공정도, Alarm, Trend, Report, Fault 등 현장 설비 운용에 대한 정보를 감시하고 제어하며, 사용자에게 현재 상태나 과거기록 등에 대한 정보를 보여준다.The substation monitoring system installed in such substations monitors and controls the information on field facilities such as process charts, alarms, trends, reports, and faults, and shows the user the current status and historical records.

모니터링 시스템은 하위그룹과 상위그룹의 중간통신 프로토콜을 이용해 하위그룹(예를들면 IED)의 데이타를 상위그룹(HMI)으로, 상위그룹의 운영자 작동상태를 하위그룹의 IED로 전달하는 기능을 갖는다.The monitoring system has the function of transmitting data of the subgroups (eg IED) to the upper group (HMI) and the operator operation status of the upper group to the IED of the lower group by using the intermediate communication protocol of the lower group and the upper group.

통상적으로 하위그룹과 상위그룹의 통신시 보통 사용되는 프로토콜은 자체에서 개발한 프로토콜이나 TCP/IP기반의 프로토콜, UDP 기반의 프로토콜을 많이 사용 한다.In general, protocols commonly used for communication between lower and upper groups use protocols developed in-house, protocols based on TCP / IP, and protocols based on UDP.

그러나, 종래의 모니터링 시스템은 상위시스템과 하위그룹의 통신프로토콜이 상이할 경우 하위그룹의 동작상태 감시가 원활히 이루어지지 않게되어 변전소 모니터링 기능이 상실되는 문제점이 있었고, 또한, 데이타를 효율적으로 관리할 수 없게되는 문제점이 발생하고 있었다.However, in the conventional monitoring system, when the communication protocols of the upper system and the lower group are different, the operation state monitoring of the lower group is not performed smoothly, and thus the substation monitoring function is lost, and the data can be efficiently managed. There was a problem of disappearing.

따라서, 상기 문제점을 해결하기 위한 본 발명은 각종 현장기기의 작동상태정보 및 경보정보를 수집하여 상위시스템에 제공하는 다수의 IED와; 상기 IED와는 IEC61850 통신프로토콜을 통해 데이타를 교신하면서 IED의 운전상태 데이터를 수집, 저장 및 계산 처리함은 물론 수집된 정보를 화면 또는 그래프를 통해 실시간 데이타로서 제공하여 IED의 상태정보를 상위시스템에서 모니터링 및 감시제어할 수 있도록 하는 HMI 플랫폼; 로 구성하므로서, 변전소에 설치된 IED의 작동상태 정보를 상위시스템에서 효율적으로 모니터링하여 감시, 제어할 수 있도록 한 변전소 모니터링 시스템을 제공함을 목적으로 한다.Accordingly, the present invention for solving the above problems is a plurality of IEDs to collect the operating status information and alarm information of the various field devices to provide to the upper system; The IED communicates with the IED through the IEC61850 communication protocol, collects, stores and calculates the operation status data of the IED, and provides the collected information as real-time data through a screen or a graph to monitor the status information of the IED in the upper system. And an HMI platform for monitoring and controlling; It is an object of the present invention to provide a substation monitoring system capable of efficiently monitoring, monitoring, and controlling the operation state information of the IED installed in the substation in the upper system.
