PROBLEM TO BE SOLVED: To unify protection methods by collecting information required to protect respective transmission lines at one place to collectively protect the transmission lines by a common processing unit or the like, save labor in maintenance by remote maintenance function, and slim down facilities by integrating respective functions such as remote monitoring control function and remote maintenance function in addition to speed up of breaking time and existing transmission line protection function.;SOLUTION: The total protection method of a power system unit monitors accidents or the like occurring in a substation and respective electric stations to which electric power of a power plant is transmitted and in transmission lines. The information required when protecting respective electric stations and transmission lines is collected in a control station 2. Accidents or the like occurring in transmission lines and a controlled station 1 are collectively monitored and protected by the common processing unit 3 in the control station 2.;COPYRIGHT: (C)2004,JPO
