Methodology of online assessment of technical state of transformer substation 35/6 (10) kV by express analysis coefficient

THE PURPOSE. The purpose of this study is to develop a methodology for determining the coefficient of express analysis of the main equipment of a 35/6 (10) kV transformer substation (TS) to assess its technical condition. A three-level structural complex has been developed for measuring and express-analysis of the technical state of TP. The technical condition of the main equipment of the TP is analyzed according to the selected diagnostic parameters.

METHODS. The TP monitoring system makes it possible to assess the performance of its elements online. Express analysis provides remote monitoring, monitoring of the condition of the operating equipment and forecasting changes in the technical condition.

RESULTS. The proposed method for determining the coefficient of express analysis allows online monitoring of changes in monitored parameters, reducing the recovery time of failed elements, and maintaining equipment in a working condition.

CONCLUSION. The proposed solutions make it possible to move to the organization of maintenance and repair of the main power and electrical equipment of the transformer substation according to the actual state, as well as to improve the reliability and quality of the transmission of electrical energy to consumers.
