TLDR
It was revealed that a large number of secondary circuits used in digital measuring instruments and interface devices negatively affect the reliability of digital substation units.Abstract:
The paper deals with the problem of improving the reliability of digital power supply facilities, namely digital substations. The goal of the study is to identify factors of a negative impact on the digital substation reliability indices. Based on the influencing factors analysis, technical measures for increasing reliability indexes are proposed. Based on the basic principles of the classical theory of reliability a numerical estimate of the probability of failure-free operation for the main equipment digital substation was made taken as an example the real digital substation switchgear 220 kV. Detailed equivalent circuits are given to ensure the reliability of the main units of digital substations. The numerical values of the reliability indices of the main elements are given in tabular form. The digital substation blocks with low reliability indices, as well as the most vulnerable elements of equivalent circuitry of its nodes, are identified. It was revealed that a large number of secondary circuits used in digital measuring instruments and interface devices negatively affect the reliability of digital substation units. Recommendations on maintaining the required level of reliability of power supply are given.read more
