The article analyzes the problems arising during the operation of electrical equipment of pumping stations when the voltage in the power supply system changes. An analy-sis of the negative impact of mains voltage deviation on the starting and operating modes of operation of pumping units is made. On the example of pumping stations in the Sughd region of the Republic of Tajikistan, the causes and frequency of shutdowns of pumping stations are in-vestigated. The main factors affecting the operation of the electrical equipment of pumping sta-tions are determined, an analysis of the parameters of power quality affecting the operation of pumping stations is carried out. The features of the operation of synchronous motors of pump-ing station units with a change in voltage in the power system are revealed. The main factors affecting the operation of electrical equipment of pumping stations are considered. The analysis of power quality indicators affecting the operation of pumping stations was carried out. The features of the operation of synchronous motors of pumping station units are indicated. The re-sults of a study of the impact of changes in the electrical parameters of the energy system of the Sughd region on the operating modes of pumping stations and other irrigation water facilities are presented. Among them: small and large disturbances in the power system, frequency ripple in the network at various voltages, disconnection of powerful electricity consumers, start-up of synchronous motors on high-voltage equipment operating in parallel.
