Remote secondary equipment analog quantity intelligent diagnosis method based on dispatching master station

The invention provides a remote secondary equipment analog quantity intelligent diagnosis method based on a scheduling master station, and the method proposes a typical analog quantity channel matching method on the basis of researching the uncertain matching factors of different versions of protection devices of different relay protection manufacturers, such as non-corresponding channel names and inconsistent channel configuration numbers. By means or methods of on-line comparison, waveform characteristic analysis and the like, the correctness of the analog quantity sampling, calculation and transmission process of the secondary equipment is comprehensively analyzed, and the defects in the aspects of secondary circuit wiring, device analog quantity, channel delay parameter setting and the like are found in time; on-line analog quantity monitoring and intelligent diagnosis functions are realized through the typical analog quantity analysis and diagnosis method of the relay protection equipment, and the accura
