Zusammenfassung:	A tube leakage detection system capable of monitoring tube leakage and estimating a location using acoustic emission signals and/or operation signals of a power generation facility is disclosed. The tube leakage detection system comprises: a sensor block that detects status signals of a power generation facility; a collection part that collects the status signal; a calculation part that calculates a probability distribution for each sensor using the collected status signals; and an analysis part that estimates whether there is a leak in a tube of the power generation facility according to the probability distribution for each sensor. 발전 설비의 음향 방출 신호 및/또는 운전신호를 이용하여 튜브 누설을 감시하고 위치를 추정할 수 있는 튜브 누설 검출 시스템이 개시된다. 상기 튜브 누설 검출 시스템은, 발전 설비의 상태 신호를 검출하는 센서 블럭, 상기 상태 신호를 수집하는 수집부, 수집된 상기 상태 신호를 이용하여 센서별 확률 분포를 계산하는 계산부, 및 상기 센서별 확률 분포에 따라 상기 발전 설비의 튜브에서 누설 여부를 추정하는 분석부를 포함하는 것을 특징으로 한다.
