According to the reporting information published on the official website of SO UPS JSC, from January 1 to June 30, 2022, 24302 cases of activation of relay protection devices were recorded in the UPS of Russia. The number of correct responses was 23259 or 95.71%.

The maximum number of cases of incorrect operation of RPA devices in the reporting period was associated with the failure to take or untimely measures to extend the service life or replace the RPA equipment and its auxiliary elements (19.67%), defects (shortcomings) in the design, manufacture (10.80%), as well as erroneous actions of the personnel (8.35%). The main technical reasons for incorrect operation of RPA devices were defects or malfunctions of electromechanical equipment (16.58%) and secondary circuits of RPA (13.88%), as well as physical deterioration of equipment (7.46%).

The reports were generated on the basis of operation analysis of more than 150 thousand relay protection and automation devices at electric power facilities of a voltage class of 110 kV and higher in accordance with the requirements of the Rules for Technical Accounting and Analysis of the Functioning of Relay Protection and Automation Devices, approved by the Order of the Ministry of Energy of Russia No. 80 dated 08.02.2019. According to the principles set out in the document for providing data, the results of the operation of relay protection and automation devices are grouped separately by types of equipment. Cases of incorrect operation are additionally classified by types of organizational and technical reasons.

Monitoring of operating conditions and results of operation of relay protection and automation devices is one of the key business processes of the System Operator and is carried out as part of the provision of services for operational dispatch control of the UPS of Russia. The main goal of the initiative of the System Operator to open public access to the results of the analysis of relay protection devices functioning across the UPS of Russia is to assist electric power organizations in assessing the effectiveness of the relay protection and automation systems used, which are the most important mechanism for maintaining the reliability and survivability of the UPS of Russia, identifying the characteristic causes of incorrect operation, as well as the development of optimal solutions to eliminate shortcomings and sophisticate relay protection devices.

The next reports on the results of the operation of relay protection and automation devices in the UPS of Russia for the first half of 2022 are available in a special section of the official website of SO UPS JSC. Currently, information is also available here on the results of the operation of relay protection and automation devices in the UPS of Russia for 2019, 2020 and 2021.
