Abstract: The high frequency switch power supply, reliable in performance, small in volume and high in efficiency, has been widely used in smart substation DC system, which guarantees the substation’s safe and reliable operation. The integrated AC/DC power system is firstly introduced, and then the DC charging module, communication power supply and UPS power supply module are analyzed respectively in detail, and the N+1 redundancy technology and current sharing technology of the high frequency switch power supply are studied specially. The result shows that application of these two kinds of technology can improve the reliability of the high frequency switch power supply module. The high frequency switch power supply can meet the requirements of intelligent substation on DC system’s reliability.

Key words: smart substation, DC system, high frequency switch power supply, UPS, communication power supply, redundancy technology, current sharing technology
