FIELD: electricity. ^ SUBSTANCE: reversible controlled electric connections are generated in the required areas of interruption for flow of short-circuit currents by placement of modules of a multimodule DC insert, besides, the required number of controlled links C and the number of modules m required for their formation are related by the following ratio: A multimodule DC insert comprises m converting modules, every of which represents a reversing controlled converting device of an alternating current or voltage into a direct one, each connected to their unit at the AC side, and at the DC side connected in parallel to the common DC buses. ^ EFFECT: reliability improvement. ^ 2 cl, 3 dwg |
