Calculation and analysis of reliability of power output circuits of Boguchany Dam has been performed, which allows to identify types of accidents, to determine the frequency of their occurrence and the terms of liquidation for them. With the help of the obtained values of frequencies and duration of accidents, it is possible to determine the relative undersupply of energy to consumers and reduction of electric power generation by the station, which makes it possible to estimate the value of mathematical expectation of economic damage.

The problem of electromagnetic compatibility of users that have a mutual supply center is examined. On the basis of field studies, the levels of higher harmonic components of current and voltage were determined at an operating steel plant with induction heating electrical installations. Simulation model of steel plant with electrical installations of induction heating is presented, which includes controlled filter-compensating devices and fuzzy logic controller, for which product rules of fuzzy interference are formulated. It is shown that the use of a fuzzy logic controller allows limiting the level of higher harmonics of current and voltage during operation of the induction furnace.
