Abstract
A device for controlling a high voltage direct current (HVDC) transmission system is provided. The device includes: a communication unit communicating with a control device; a control unit obtaining a databack signal received through the communication unit, checking a data line error and a line connection error based on an obtained databack signal, and outputting a valve control signal based on the databack signal; and an output unit outputting the valve control signal to a valve control device based on control of the control unit.
Claims18
A device for controlling a high voltage direct current (HVDC) transmission system, the device comprising:
- a communication unit configured to communicate with a control device;
- an output unit configured to output information;
- and
- a control unit configured to:
- control the communication unit to obtain a databack signal;
- check for a data error based on error data included in the obtained databack signal;
- check for a line connection error based on whether the databack signal is obtained;
- and
- control the output unit to output a notification that the data error or the line connection error occurs,
- wherein the control unit is further configured to check for the data error and the line connection error together based on a same databack signal.
A method of controlling a high voltage direct current (HVDC) transmission system, the method comprising:
- obtaining a databack signal from the HVDC transmission system;
- checking for a data error based on error data included in the obtained databack signal;
- checking for a line connection error based on whether the databack signal is obtained;
- and
- providing a notification that the data error or the line connection error occurs,
- wherein checking for the data error and the line connection error is performed together based on a same databack signal.
