description: This work contains the calculation of power losses in the power supply scheme of the lumber mill No. 3. A quantitative analysis of losses is given in the existing scheme. Options and activities to reduce losses are considered, including the alternative of the wires in order to increase the conductive square and the installation of the optional powerful transformers. The calculation of power losses for two types of reconstruction was carried out, the recommendations on the most effective ways to minimize losses are given. All the electrical equipment on the station was checked, including the switchers, cut - offers and transformers. The calculation of differential and maximal power defense was carried out, the time of switching on the defense from overload was chosen, after consuming all this - the parameters of transformer relay protection of the main step-down sub-station were determined. The calculation of fault current was carried out, on the basis of which the two-step power protection with the action to switch off the cable line with one-sided connection was chosen. The calculation of economical data for the variant of decreasing losses under compensation the reactive power on the main substation was carried out, on the base of it the conclusion of economical efficiency was done. The list of organizational and technical measures was given.
