The invention discloses a method for generating intelligent busbar differential protectors and corresponding intelligent interval protectors for substations. The method comprises controlling screen erection and powering on of novel busbar differential protectors, and dismounting original busbar difference devices based on the reserving of original busbar differential protector screens; placing busbar difference transition interface devices at the position, where the original busbar difference devices are mounted, and configuring the busbar difference transition interface devices; connecting the busbar difference transition interface devices with original repeat relays and with original breaker protectors and original breaker primary devices afterwards; controlling interval transformation; lapping the intervals with the novel busbar differential protectors. By the aid of the method, conventional busbar protectors and corresponding interval protectors can be changed into intelligent busbar protector and corresponding intelligent interval protectors safely.
