Development and research of a flexible intelligent electrical network of medium voltage, based on a hexagonal structure

摘要

Intelligent technologies in the distribution network complex should solve the following problem: improvement of reliability of power supply to consumers; survivability and controllability of systems of power supply, reduction of power losses; increasing the length of the maintenance period between repairs; minimization of damage from accidents and shutdowns; increase of energy efficiency and quality of electric energy. Historically, the existing distribution network of medium voltage were not adapted to the big power flow and reconfiguration, depending on the operating mode. Therefore, the construction of energy-efficient intelligent power supply systems in existing radial and trunk topological solutions is not appropriate. We propose an innovative way to distribute electrical energy for hexagonal-topology defined voltage class and mode of grounding-neutral network. There have been made model experiments of emergency modes were made and new type of relaying network.
