ANNOTATION

The course work was done based on the task issued Functional properties of elements of the power grid.

Under the given variant is selected hydrogenerator, and described method of choice transformers, transmission lines and major equipment and they were selected (block transformer, transformer of own needs, transmission line). The equivalent circuit scheme of the given power grid was constructed and its parameters are calculated. The voltages at the node load values were found for load power 80%, 50% and 0% (no load) of the nominal value of power of the generator and built some vector diagrams between voltage generator and load voltage. The software package Mathcad was used for calculations. Also voltage transformers were described, their purpose, the basic parameters, circuit connections of windings and design.

The course work consists annotation, introduction, list of symbols, two chapters and the list of references, in general 31 pages of the printed text.
