The use of Extended Petri Nets in Analyzing the Reliability of MV/LV Distribution Transformer Stations

摘要

Studies aimed at analysing and evaluating the reliability properties of electrical equipment are vital for the proper operation of equipment in companies involved in the distribution of electricity. The results of this analysis have the potential for contributing to the optimal design and operation of power equipment in the future. The systematically increasing unit power rating of stations and MV lines increases the risk of exclusion of larger power values in the event of their failure, and therefore greater restrictions in the supply of electricity to consumers. This results in considerable material losses and, in extreme cases can lead to health hazards or the loss of human life. Certainty the supply of electricity to consumers is a serious problem for network companies, especially for those distribution companies directly responsible for servicing customers. Power outages are responsible for economic and financial losses of distributors as resulting from the costs of repair as well as the reduction of power consumption by the public during the time of failure.
