GB/T 40864-2021 Technical requirements for relaying protection of flexible alternating current transmission equipment connecting to the system
Abstract
This document specifies the general requirements, functional configuration, and setting calculations for flexible AC transmission equipment and the associated relay protection of the power grid to which it is connected.
This document is applicable to common flexible AC transmission equipment such as series capacitor compensation devices, unified power flow controllers, and fault current limiters in power grids with voltages of 220 kV and above; controllable parallel reactors in power grids with voltages of 500 kV and above; and dynamic reactive power compensation devices in power grids with voltages of 35 kV and above.
