Three-terminal power line fault location and correction system and method, and computer readable storage medium

A three-terminal power line fault location and correction method, which is applied with a fault location and correction system, the fault location and correction system comprising three terminal devices, a power line and an electronic device, the terminal devices being connected to a divergence point of the power line and positioned at three terminals of the power line, the electronic device being electrically connected with the terminal devices;

• wherein when a fault occurs at a certain position of the power line, the fault location and correction method comprises steps of:
• each of the terminal devices detecting the fault to generate a fault distance corresponding to the fault;
• and
• the electronic device correcting the fault distance as follows:
• the corrected fault distance of one of the terminal devices=(an actual distance between the terminal device and a divergence point+a function of actual distances between the other two terminal devices and the divergence point)*the fault distance corresponding to the terminal device/(the fault distance corresponding to the terminal device+a corresponding fault distance with respect to a function of the actual distances between the other two terminal devices and the divergence point).
