Research on Secondary Equipment Configuration of Power System Suitable for New Energy Stations

This article introduces the operating characteristics and startup methods of distributed synchronous condenser-transformer unit, and proposes their protection configurations during the startup process. And the principle and logic of different demagnetization protection, power-off protection, and third harmonic stator grounding protection between distributed synchronous condenser-transformer unit and conventional generators were emphasized. At the same time, referring to national norms and standards, a relay protection configuration scheme for distributed synchronous condenser-transformer unit has been proposed, providing reference for the construction of new energy station installation of distributed synchronous condenser-transformer unit projects.
