Description

Изобретение относитс  к устройствам дл  передачи электроэнергии .The invention relates to devices for the transmission of electricity.

Известно устройство дл  передачи электроэнергии, содержащее многополюсные синхронные генераторы , каждый из которых имеет магнитно не св занные параллельные ветви обмотки статора, по крайней мере, две линии электропередачи и трансформаторы между синхронными генераторами и лини ми электропередачи. Однако известное устройство характеризуетс  уменьшением пропускной способности линии электропередач по услови м динамической устойчивости.A device for transmitting electrical energy is known that contains multi-pole synchronous generators, each of which has magnetically coupled parallel branches of a stator winding, at least two power lines and transformers between synchronous generators and power lines. However, the known device is characterized by a decrease in the transmission capacity of the power line under the conditions of dynamic stability.

Цель изобретени  - повышение предела динамической устойчивости электропередачи.The purpose of the invention is to increase the limit of the dynamic stability of power transmission.

Это достигаетс  тем, что ветви обмоток статора, принадлежащие синхронному генератору, подключены к разным электрически не св занным трансформаторам.This is achieved by the fact that the branches of the stator windings belonging to the synchronous generator are connected to different electrically not connected transformers.

На чертеже представлена схема предложенного устройства.The drawing shows a diagram of the proposed device.
