高压直流系统的冗余控制设备和方法
摘要：
本发明提供了一种高压直流(HVDC)传输系统的冗余控制设备。该冗余控制设备包括：第一系统和执行与第一系统的功能对应的功能的第二系统，以及第一逻辑切换器(COL)和第二COL，其判定是否在第一系统和第二系统之间切换，其中光通信模块存在于第一系统和第一COL之间、第一COL和第二COL之间以及第二系统和第二COL之间以发送并接收数据，并且第一COL和第二COL包括检查光通信模块的连接或线路状态以及传输数据的有效性的监测控制单元。
摘要（英）：

A redundant control device of a high voltage direct current (HVDC) transmission system is provided. The redundant control device includes a first system and a second system that performs a function corresponding to that of the first system; and a first change over logic (COL) and a second COL that determine whether to switch between the first system and the system, wherein there are optical communication modules between the first system and the first COL, between the first COL and the second COL, and between the second system and the second COL to transmit and receive data, and the first COL and the second COL includes a monitoring control unit that checks a connection or wiring state of the optical communication modules and validity of transmission data.
