摘要
A method for securing the program safety of an HVDC system according to the present invention comprises the steps of: calculating, by a controller of the HVDC system, a BIOS program eigenvalue after loading a BIOS when power is applied; receiving, by the controller, a BIOS program eigenvalue of the controller prestored in a higher system of the controller; and comparing the BIOS program eigenvalue calculated in the controller and the BIOS program eigenvalue prestored in the higher system so as to identify whether or not the eigenvalues are identical and, if the eigenvalues are not identical, stopping execution of a program and notifying the higher system that the eigenvalues are not identical.
