Abstract
In Part 1, a generalized equivalent circuit of information sensors of devices for relay protect ion and automation is developed. The development was able to be performed sequentially from the upper hierarchical level of information processing in the system to the lower in the device. A hierarchical systematization of the Ψ-structures of known and new information sensors has been compiled, which makes it possible to evaluate the relative effectiveness of their structures. In Part 2 modeling was performed using a sequence of developed schemes for passing a specific information signal component from the point of formation in a 6–35 kV distribution network to output, for example, in a SCADA system. Estimated difference in the formation of selectivity and blocking circuits at the very initial level of the structure of the device. This level is implemented jointly on the same structural elements. Found that some well-known algorithms of devices and terminals should be attributed to the initial morphological level of information processing. Then they become effective smart sensors. The necessity of building smart sensors is shown as well. The difference in ways of increasing the selectivity and quality of blocking between the morphological and other hierarchical levels is also illustrated.
