| Summary: | The issues of introduction of electrical digital substations
in the Russian Federation are considered. An existing
criteria analysis for assessing the modern relay protection
devices efficiency is carried out and an assessment of their
sufficiency is made. A mathematical model development of
the digital substations relay protection complexes operation
has been developed using the queuing theory, the graphs
theory and Markov chains. The failure-free operation
probability calculated value of the relay protection
complexes corresponds to the long-term analysis data.
This indicates that the mathematical model is correct. The
proposed mathematical model makes it possible to take
into account the impact of the maintenance quality on the
digital substation relay protection complexes efficiency. |
