IEEE 2745.4-2022

This guide specifies the application of control and protection on a unified power flow controller (UPFC) using a modular multilevel converter (MMC) in transmission lines, including application considerations, protection functions and performance, control strategies, and monitoring functions, as well as test and commissioning approaches. The guide also provides informative case studies of control and protection systems based on the application experience of UPFC projects.

The purpose of this guide is to provide technical guidelines for the design, research, development, implementation, operation, maintenance, as well as testing of UPFC systems using MMC. Utilities, manufacturers, and other interested entities can use this guide to specify application requirements, define protective and performance functions, control strategies and monitoring functions, testing and commissioning of UPFC control and protection systems.

New IEEE Standard - Active. The application of control and protection on a unified power flow controller (UPFC) using a modular multilevel converter (MMC) is specified in this guide, including application considerations, protection functions and performance, control strategies, and monitoring functions, as well as test and commissioning approaches. This guide can be used as the basis for the design, manufacture, testing, and commissioning of UPFC control and protection systems, benefiting both utilities and manufacturers.
