摘要

本文介绍了MON.ITA高压直流线路保护系统的各个部分,并根据不同的配置可能性进行了设计。介绍了400/205/ 205kv交流继电器,包括交流接线、滤波器、变压器和直流继电器,并对整个保护系统进行了功能描述。在直流部分,对交直流转换系统、直流电缆和共中性点系统的保护进行了综述。根据故障的严重程度,解释了一般保护标准、管理主要关键事件和停止AC/DC转换的操作顺序所采用的方案。

MON.ITA HVDC Link AC & DC Protection System
This paper describes the protection system of MON.ITA HVDC Link in all its parts, which has been designed taking into account the different configuration possibilities. AC protection relays, including AC connections, filters and transformers 400/205/205 kV and DC protection relays are presented with a functional description of the entire protection system. Regarding DC part, the protections of AC/DC conversion system, DC Cables and Common Neutral system are reviewed. General protection criteria, adopted schemes to manage main critical events and operating sequences to stop AC/DC conversion, depending on the severity of the fault, are explained.
