Circuit single-end ranging method based on phase aberration characteristic of positioning function

The invention belongs to the technical field of power system relay protection, and discloses a circuit single-end ranging method based on phase aberration characteristic of positioning function. The method deduces an operating voltage of reference positions and a fault point voltage based on distribution parameters by using electric quantity of a single end, and constructs a positioning function. When the reference positions are positioned on the left side and the right side of fault point, the positioning function has different phase characteristics; and when the reference positions are changed in front and back of the fault point, the phase of the positioning function has a unique stepped aberration. A circuit is subjected to N equal distribution, the equal distribution area containing the fault point is determined by using the phase characteristics, the step length is further reduced to determine the phase aberration position in the area, and then quick fault positioning of the single end can be realized. The method overcomes the defects of the traditional single-end ranging method, and theoretically is not affected by the factors such as distributed capacitance, transition resistance, opposite side running mode, communication facilities, load current and the like. The algorithm is simple, reliable and easy to realize, and the use value of the method is strong.
