T/CEC 380-2020 Flexible DC Transmission Project Transformer Module Fault Waveform Recording Technical Specification for Switching Valve
Basic Information
Scope
This document specifies the interface and configuration of the fault recording data of the converter valve sub-module in a modular multi-level flexible DC transmission project, the content and format of the fault recording data, the accuracy and duration of the fault recording data time, the sampling frequency, the start-up mode, the data caching, the fault message of the sub-module, etc. This document is applicable to the design of the fault recording system for the converter valve sub-module in a modular multi-level flexible DC transmission project. The design of the fault recording system for other voltage-source converter sub-modules adopting a modular multi-level topology, such as static var compensators and unified power flow controllers, can be used for reference.
