디지털 보호계전기의 고장데이터 원방 취득 시스템 {A system for acquiring fault data from digital protective relays through wide area network}System for acquiring fault data from digital protective relays {A system for acquiring fault data from digital protective relays through wide area network}

본 발명은 디지털 보호계전기 고장데이터 원방 취득 시스템에 관한 것으로, 보다 상세하게는 원거리통신망을 통해 원방의 디지털 보호 계전기들로부터 고장데이터를 취득할 수 있는 디지털 보호계전기 고장데이터 원방 취득 시스템에 관한 것이다.The present invention relates to a digital protection relay failure data remote acquisition system, and more particularly, to a digital protection relay failure data remote acquisition system capable of acquiring fault data from remote digital protection relays through a telecommunication network.

일반적으로, 전력계통 보호를 위해 설치된 디지털 계전기들은 평상시 계통의 상황은 물론, 계통 사고시 사고발생 전후의 상황에 대한 유용한 정보를 내부에 저장하고 있으며 이러한 정보를 계통 및 사고분석을 위해 유용하게 사용된다.In general, digital relays installed for power system protection store useful information about the situation of the system as well as the situation before and after the occurrence of an accident in a system accident, and this information is useful for system and accident analysis.

그런데, 종래에 설치·운영되고 있는 디지털 계전기들은 대부분 데이터 전송을 위해 시리얼(Serial) 통신을 지원하므로 통신거리가 단거리인 한계가 있으며, 특히 제작사마다 각자의 계전기에 맞는 각자의 분석소프트웨어를 사용하고 있으므로 변전소에 설치된 계전기에 저장된 데이터를 원방에서 취득하는 것이 불가능하다.However, most of the digital relays installed and operated in the past support serial communication for data transmission, so there is a limit of short distance. Especially, each manufacturer uses their own analysis software for each relay. Data stored in relays installed in substations cannot be acquired remotely.

이로 인해, 사고 발생시 사람이 직접 변전소에 가서 고장데이터를 취득해야 하는 불편함이 있었을 뿐만 아니라, 데이터를 취득 및 분석하는 데 시간적 지연이 발생하는 문제점이 있었다.As a result, in the event of an accident, a person has to go directly to a substation to obtain fault data, as well as a time delay in acquiring and analyzing data.

이에 본 발명은 상기한 종래기술의 문제점을 해소하기 위해 안출한 것으로, 원방의 디지털 계전기로부터 데이터를 취득할 수 있는 디지털 보호계전기 고장데이터 원방 취득 시스템을 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a digital protection relay failure data remote acquisition system capable of acquiring data from a remote digital relay.
