The invention discloses a defect identification method for a comprehensive converter station with a template, and the method comprises the steps: 1, obtaining a reference picture and a to-be-detectedpicture in a converter station sample library, the sample library being a set of reference pictures, the reference picture being a normal picture when the converter station has no hidden danger, the to-be-detected picture being a picture which is shot in real time and has the same converter station position; 2, obtaining a difference graph of the reference picture and the to-be-detected picture inthe sample library by integrating the simultaneous comparison results of two or more detection algorithms; and 3, prompting the possible position of the hidden danger according to the difference graph. The method can effectively improve the defect recognition accuracy of an existing converter station, reduce the possibility of false alarm and missing alarm, and reduce the burden of a worker. 本发明公开了一种带有模板的综合型换流站缺陷识别方法，其步骤包
