The possibility of using heat pump installations at thermal power plants is considered. An estimation of the sources of low-potential heat for the operation of the heat pump in the joint generation of electrical and thermal energy was carried out. The results of a comparative analysis of the schemes for the inclusion of a heat pump in the cooling system of recycled water are presented using the example of the Kirov thermal power plant.

The low quality of the new rolling bearings leads to additional costs for electric motor repair, and additional expenses connected with the technological process, value of which can reach from several thousand to tens of thousand dollars. To increase detection, the reliability of rolling bearing defects of asynchronous motors, complex vibration diagnostics was used at informative frequencies in the vibration frequency and amplitude in the range of 5-5000 Hz. Based on the diagnostic model of rolling bearings the software program "Tayamnitsa" is developed, which allows to calculate the diagnostic frequency corresponding to certain defects, determine the defect level and form a diagnostic table for defects. Vibration diagnostics of new and used rolling bearings have been conducted for various regional enterprises and power plants. It has been determined that 40-50% of used bearings are removed in good technical condition. When new bearings were diagnosed in the 500-5000 Hz range, only 48.4% of the bearings are considered serviceable due to the low accuracy class of metal processing and unacceptably high vibration level.

In this paper, a model of personnel activities in emergencies during the operation of an electric power facility is proposed. The factors that characterize the inerrancy of the activities of operational personnel and their relationships that determine the effectiveness of actions are identified. The efficiency of various strategies of human behavior is a function of properties of the situation, technical condition, as well as characteristics of equipment and professional attributes of the person.
