Abstract
Joint Stock Company (JSC) “Mine Aleksandrovsky” is located in the Mogochinsky district of the Trans-Baikal Territory. “Mine Aleksandrovsky” concluded an energy supply agreement with JSC “Chitaenergosbyt” for the purchase of electric energy from it. In accordance with the contract, the electric energy supplier undertakes to supply electric energy that meets the requirements of the current legislation of the Russian Federation. The power quality in the Trans-Baikal Territory in most regions does not meet the requirements of State Standard 32144-2013. Suppliers and the network organization are responsible to consumers for the reliability of its electric energy supply and its quality within the boundaries of their electric networks. Despite the obligations of the contract, the electric energy supplied to “Mine Alexandrovsky” does not meet the requirements. In 2017 the ball mill engine in the shredding department of the gold recovery factory failed as a result of power outages and the supply of low power quality through the 6 kV line. The article provides information on interruptions in power supply over the years of operation of the enterprise, the results of analysis of the power quality, information on damage to electrical equipment caused by low power quality, and economic damage.
Highlights
In Russia, there is a big problem with the power quality [1]
New mandatory regulatory and technical documents governing the relationship between the utility and consumers in the field of power quality have not been developed, the law states that all entities of the electric power industry are obliged to supply consumers with electrical energy, the quality of which corresponds to “technical regulations and other mandatory requirements”
The entities of the electric power industry engaged in the power supply to consumers do not want to deal with the power quality themselves, because it is unprofitable, and, as a result, consumers suffer by buying low power quality [6, 7]
Summary
Before the Law “On Electric Power Industry” was enforced in 2003 [2], the country had had an economic mechanism for managing the power quality. It was presented in three documents [3,4,5] and obliged both the utility and consumers of electrical energy to deal with its quality. New mandatory regulatory and technical documents governing the relationship between the utility and consumers in the field of power quality have not been developed, the law states that all entities of the electric power industry are obliged to supply consumers with electrical energy, the quality of which corresponds to “technical regulations and other mandatory requirements”. The entities of the electric power industry engaged in the power supply to consumers do not want to deal with the power quality themselves, because it is unprofitable, and, as a result, consumers suffer by buying low power quality [6, 7]
