Contributions to monitoring the condition of substations

摘要

By promoting modern and competitive techniques and equipment for online monitoring and diagnosis, it is possible to track natural or accidental degradation over time. If identified in time and remedied, it will not generate serious events which may be sources of extremely costly damage for electric power suppliers and consumers. At the same time it is possible to extend the life of the equipment, optimize the maintenance program and reduce the outages and expenses for planned repairs. The paper presents an analysis of the vital parameters of MV, LV transformer substations and proposes a system for monitoring their working condition. The main objective of the paper is to present a modular system for transformer substation monitoring in order to increase the quality of electric power supply for consumers and reduce the costs of equipment overhaul and maintenance. Based on the considerations on the transformation substation condition monitoring, the paper presents achieved of such a monitoring system, which can be integrated into SCADA.
