The invention discloses a power monitoring system security protection compliance detection method and system. The method includes the following steps that: a detection instruction book is obtained from a test management platform, wherein the test instruction book is generated by the test management platform according to a detection item, wherein the detection item is constructed by the test management platform according to a detection object and a compliance index associated with the detection object; the detection instruction book is analyzed, so that the detection object and the compliance index associated with the detection object are generated; data acquisition is carried out according to the detection object and the compliance index associated with the detection object; conformity judgment is performed on a data acquisition result and a compliance index stored in a compliance library; and a detection result is generated according to a conformity judgment result and the requirement of the compliance index stored in the compliance library. With the power monitoring system security protection compliance detection method and system of the invention adopted, the problems of low detection efficiency and low accuracy rate of conventional compliance detection can be solved, and detected objects can be continuously detected to avoid omission.
