Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.
[0030] like figure 1 As shown, this embodiment provides a dual-set redundant switching method for substation measurement and control devices. The substation includes a process layer, a plurality of measurement and control devices and a station control layer composed of a monitoring system. The measurement and control devices perform self-inspection at the same time during operation, based on The result of the self-test switches the operating mode of the device according to the preset logic.
[0031] like figure 2 and image 3 As shown, the results of the self-test includ...
