The invention discloses an optical fiber independently-coordinated protection method for an integrated and intelligent terminal of a switching station. Fault isolation is performed on logical processing in the terminal by independently-coordinated interactive fault information between terminals, a switch nearest to a fault point performs protection action, the power-failure range is reduced to thegreatest extent, a power distribution master station or sub-station is not needed to participate during the fault isolation process, and the problems that the terminal is no high in on-line rate, a fault isolation algorithm dependents on the main station, the circuit switch acts for many times and a circuit is impacted for many times during automatic construction of a concentrated feeder are prevented.
