Annotation

In this thesis project considers the issues of design of electrical networks based on the existing 110 kV line. We consider three variants of network development, with all options produced by the voltage selection network, sections of transmission lines, transformers step-down substations and circuit switching.

Of the three schemes by technical and economic comparison for further consideration on the quality of electricity was one scheme.

In accordance with the mission designed the substation 110/10 kV. The system on 110 kV overhead line, the consumer chemical industry, Pmax10=20 MW.

The project is compiled only option structural diagram for a node 14 of a second embodiment of network development, is the choice of transformer, calculation of the number of lines, selection of schemes of switchgears, developing the scheme of power supply of own needs of substations. For this scheme, calculation of short circuit currents. According to the obtained results of calculation of short circuit currents produced by selection of circuit breakers, disconnectors, current-carrying parts of the substation.

In the section specials. the question is considered devices reactive power compensation
