Provided is a HVDC system for checking a firing signal, which includes an upper controller which outputs a firing signal; valve based electronics (VBE) which decides that a corresponding signal is proper when a difference of phase angle between a corresponding firing signal and the phase angle signal of a system is in a normal range, in case of receiving the firing signal from the upper signal; and a thyristor valve which operates according to the firing signal distributed by the VBE and performs a switching operation for converting AC power into DC power. |
