The Power Supply Reliability of Large Industrial Consumers in the Arctic

Abstract

Features of the Russian Federation Arctic regions were analyzed. The results of electricity quality indicators (SCE) monitoring registration on tyres of substations supplying large enterprises of the Murmansk region were systematized and analyzed as a good example of Arctic industrial development. On existing substations example, the problems of high-energy-intensive objects that have non-linear load parameters as part of consumers are shown. The load of the Murmansk region industrial enterprises on the capacity of electricity consumption is systematized, since all enterprises of the region work in the mining and chemical direction. Electromagnetic compatibility problems of industrial consumers with the supply grid were identified and the results of monitoring registrations for the period 2012 – 2018 years were compared with earlier registrations of the 00s, when regular monitoring of SCE was not legally fixed. The need for studies to identify the causes of inconsistency has been proven. A number of the most general and effective measures to limit distortions in the quality of electricity are proposed.
