Title: Choice Of The Type Of Grounding The Neutral In A Medium Voltage Electrical Network
Keywords: electrical network, medium voltage, grounding of the neutral

Abstract: The paper presents the application of the method of hierarchical analysis from the mathematical theory of games for selecting an optimal variant for grounding the neutral in medium voltage distribution networks. Three options have been considered: an insulated neutral; a neutral, grounded through a resistor; and a neutral, grounded through a reactor. The criteria, used for selecting the optimal type of neutral grounding are: the efficiency indicator for the particular mode of operation; and the additional costs for construction of the respective type of neutral grounding. The mathematical apparatus of the game theory has been applied to the three variants in accordance with the two criteria. An algorithm has been developed, allowing to introduce a different weighting coefficient for the two criteria, taking into account the specific electrical network under consideration. The results from the calculations give the optimal variant of grounding the neutral in the medium voltage network
