Dependability Assessment of Western Siberia Electrical Grids

Abstract

The dependability estimating method of the extreme North areas electrical grid proposed in the work. We have developed mathematical models of reliability of power supply systems for various type consumers. These models take into account the sensitivity of consumers to specific disturbances, specific of networks exploitation and possibility of redundancy. The technique results are to determine the ways of the operational dependability improving. We suggested the directions of electrical networks dependability increase by using superfluity of consumers' reliability redundancy and the installation of protection devices for voltage dips.
