Development of operational measures for maintaining the rated value of voltage in the net-work of single-phase consumers of garden non-profit partnership

Abstract

The work examines the problems of low quality electrical energy when supplying garden non-commercial consumers in the 0.4 and 0.22 kV network. The features of the consumer network of two gardening non-profit partnerships in the Saratov region are presented, indicating the remoteness of electricity consumers. The analysis showed that the maximum distance of the end user from the transformer substation is 1400 m. For these technical parameters of the line, the dependence of the voltage losses in the line on the power and cross-section of the wire was considered. It has been established that in order to maintain the quality of electrical energy in terms of deviation from the nominal value (no more than 10 %), consumers in a line with a wire cross-section of 50 mm2 and with a uniform distribution of the consumer load along the entire length of 1400 m should consume power of no more than 500 W. Options for increasing the efficiency of operation of power supply lines with voltages of 0.4 and 0.22 kV in garden plots are proposed.
