Проблемы проектирования энергоснабжения районов мегаполисов

Аннотация

This paper considers some issues of designing power supply of mega-metropolis. The issues may be summarized as follows: the need to limit short circuit current level, rising due to development of 110/220 kV power grid and increase of power generation; the need for reactive power compensation in connection with voltage limitation on EHV transmission lines; securing SF6 circuit breaker operation in case of high rate of DC component; interesting solutions for design and development of overcurrent protection automation for power transmission lines; appropriateness of the development of centralized system for voltage control in the power system of Moscow region.
