The quality of electric energy on tires of 35 kV in the parallel work of the traction substation with a wind power plant

Abstract

The purpose of functioning of any power system is reliable and continuous provision of consumers with high-quality electric power. The current stage of development of the electric power industry is characterized by a growing shortage of energy resources received from traditional sources, therefore the use of alternative sources of electric energy with the implementation of the concept of distributed power becomes widespread. To date, Ukraine has implemented several pilot projects on the use of alternative energy sources for infrastructure supply. An urgent problem is the provision of parallel operation of medium voltage tires of traction substations with a wind power plant, as a number of requirements, including to the quality of electric energy, must be fulfilled during their operation. Accordingly, in the materials of the conducted research, the results of the experimental verification of conformity of indicators of electric energy quality on the traction substation tires to which the wind power plant is closed. The obtained results indicate that the levels of voltage deviations exceed the established norms, and the other indicators of quality of electric energy meet the requirements of normative documents.
