IEEE 2745.3-2020

This guide specifies the technical requirements for the thyristor bypass switch (TBS) used in a unified power flow controller (UPFC), including TBS structure, layout, function, performance, control, protection, monitoring, and communication interface technology. This guide also specifies testing methods that can be used as references and guidelines for design, function and performance inspection, testing, and acceptance of equipment.

The purpose of this guide is to specify technical requirements for TBSs of UPFC projects, including technical guidelines and references for testing methods for the TBS.

New IEEE Standard - Active. An approach to preparing a specification for the thyristor bypass switch (TBS) of a unified power flow controller (UPFC) using modular multilevel converter (MMC) technology is documented by this guide. The intention of this guide is to serve as a base specification to allow users to modify or develop specific clauses to meet a particular application.
