Abstract

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.

Description

technical field [0001] The present disclosure relates to a redundant control device and method, and in particular, to a redundant control device and method for a high voltage direct current (HVDC) transmission system. Background technique [0002] There are two power system interconnection methods, typically one for interconnecting the AC power system itself, and another for interconnecting the system after converting AC power into DC power through a power converter. Recently, interest in a method of interconnecting power systems after converting AC power to DC power has grown more than in a method of interconnecting the AC power systems themselves. A high voltage direct current (HVDC) transmission system using a power converter is also installed between Jeju Island and Haenam County in Korea to interconnect the power system between Jeju Island and Haenam County. [0003] The HVDC transmission method refers to a power supply method in which AC power generated at a power sta...
