Electricity Supply Schemes

The massive construction of electrical networks for the period 1960-1985 he allowed electrifying virtually all rural consumers. Almost all of them are provided with electricity from centralized power systems. Only small number of small networks of power away from the consumer is supplied with electricity from isolated, small, mostly diesel power plants. The achieved level of centralized power will bring the annual consumption of electricity in agriculture over the last decade to 5-7% of the total electricity consumption in the country. Can be considered the first phase of electrification rural customers – coverage of power "in breadth." Launched the second phase – Electrification "deep", characterized by more intensive introduction of energy in agricultural production in result of complex automation and elektromehanizatsii stationary processes, higher levels of electrification of household needs of rural population, as well as solea quality and reliable electricity supply in rural consumers. The level of exploitation of rural power networks, especially networks of 0.4-10 kV voltage does not meet modern requirements for reliability of supply of rural consumers. Overall state power grids of 0.4 and 6-10 kV characterized the data in Table. 1. Table 1 The technical condition of power grids in rural areas, state of the elements of an electric network,% good, fair unsatisfactory unfit for further use of 0.38 kV overhead line 81.6 12.9 5.5 85.8 VL6-20kV 07.10 04.05 TP 6-35/0, 38 kV 87.1 10.0 2.9 The level of electricity losses in networks Agricultural voltage of 35 kV and below about 12 96, which is approximately 2 times higher than the loss of electricity to industrial and urban networks of the same voltage class structure of energy losses in the networks of agricultural land in recent years, characterized by the data table.
