Abstract

Three solutions for novel distribution automation implemented in medium voltage networks were developed as a theoretical study. The distribution automation studied included intelligent local automation arrangements also useable for ring-type networks. The profitability of the new technique was evaluated by comparing the costs of the automation investments to the savings obtained in the economic impact of interruptions and voltage sags calculated for four different networks. The results showed that the new technique offers promising possibilities in limiting the effects of interruptions and voltage sags. The degree of automation must be adapted to each network construction. The selection of the adequate degree of automation assures the operational capability of the network company.
