Zusammenfassung: | The present invention relates to a partial discharge diagnosis and location detection method and comprises the steps of: configuring a trigger signal on the basis of a first sensing signal acquired from multiple partial discharge sensors provided at a power facility; comparing the trigger signal with a second sensing signal acquired from the multiple partial discharge sensors; detecting a partial discharge signal occurrence location on the basis of the second sensing signal extracted during a threshold time from a time point at which the second sensing signal has a value equal to or greater than the trigger signal; and finally deciding the detected occurrence location as a partial discharge signal occurrence location when the detected occurrence location is included in geographic information system (GIS) coordinates. Other embodiments are also applicable.
La présente invention concerne un procédé de détection d'emplacement et de diagnostic de décharge partielle et qui comprend les étapes consistant à : configurer un signal de déclenchement sur la base d'un premier signal de détection acquis à partir de multiples capteurs de décharge partielle fournis au niveau d'une installation électrique ; comparer le signal de déclenchement à un second signal de détection acquis à partir des multiples capteurs de décharge partielle ; détecter un emplacement d'occurrence de signal de décharge partielle sur la base du second signal de détection extrait pendant un temps de seuil à partir d'un instant auquel le second signal de détection a une valeur supérieure ou égale au signal de déclenchement ; et enfin décider de l'emplacement d'occurrence détecté en tant qu'emplacement d'occurrence de signal de décharge partielle lorsque l'emplacement d'occurrence détecté est inclus dans des coordonnées de système d'informations géographiques (GIS). D'autres modes de réalisation sont également applicables.
본 발명은 부분방전 진단 및 위치 검출 방법에 관한 것으로, 전력설비에 구비된 복수의 부분방전센서에서 획득되는 제1 센싱 신호를 기반으로 트리거 신호를 설정하는 단계, 복수의 부분방전센서에서 획득된 제2 센싱 신호를 트리거 신호와 비교하는 단계, 제2 센싱 신호가 트리거 신호 이상인 시점부터 임계시간 동안 추출된 제2 센싱 신호를 기반으로 부분방전신호의 발생위치를 검출하는 단계 및 검출된 발생위치가 GIS(geographic information system)좌표에 포함되면 검출된 발생위치를 부분방전신호의 발생위치로 확정하는 단계를 포함하며, 다른 실시 예로도 적용이 가능하다. |
