Claim 7:
8. A method for synchronizing a clock of VBE in a HVDC system, comprising:
a step of a 1PPS signal-inputting unit inputting a 1PPS signal from a time server, and a system clock-generating unit generating a system clock;
a step of a system clock-generating unit determining whether the system clock is normal or not;
a step of the 1PPS signal-inputting unit determining whether the 1PPS signal is normal or not if the system clock is determined to be normal at the step of determining whether the system clock is normal or not; and
a step of an error compensation module calculating an error of the system clock and the 1PPS signal and delivering the error to an error compensated clock generating unit, if the 1PPS signal is determined to be normal at the step of determining whether the system clock is normal or not.
