Annotation:

Heterogeneity as one of factors of increase of losses of capacity by its transfer demands constant improvement as ways of its indemnification so its estimations. Frequent changes of topology of schemes 330-750 kV and installation of devices of longitudinal-cross-section indemnification demand an estimation of heterogeneity of electric networks. On the other hand, at not the account wave properties of transfer of capacity long transmission lines, brings an error to a heterogeneity estimation. Therefore, with the account of building of new electric networks 330-750 kV the question of increase of adequacy of an estimation of heterogeneity of electric systems with long electricity transmissions is considered. Division of an estimation of influence of introduction of design decisions and operating influences for reduction of technological losses and improvement of quality of functioning of electric systems Is offered.

Key words:

electric power system, long transmission lines, heterogeneity, a integral index measure of heterogeneity
