摘要
Abstract
According to results of dynamic simulation on system-level networking of secondary equipments in digital substation, that is carried out in dynamic laboratory of simulation center owned by State Grid Corp. of China,following issues, such as the networking scheme for process level of digital substation, the rapidity of the action of protective relayings, the adaptability of protective relayings to the coordination among electronic instrumental transformers based on various principles and manufactured by different suppliers, the adaptability of protective relayings to abnormal conditions of electronic instrumental transformers, the scheme of sampling and synchronization of electronic instrumental transformers, the. data synchronization of current differential protection among digital substations and so on, are analyzed and schemes coping with these issues are proposed. Finally, an improved scheme for system-level dynamic simulation to test the networking of digital substation is given.关键词
