| description | The invention discloses a double-end fault location method for a power transmission line, and aims to solve the problem of poor model robustness caused by the fact that voltage and current are directly substituted into model training in a traditional deep learning fault location method, voltage and current are converted into relative offset for deep learning, and the robustness of the model is effectively improved. Through the provided improved grey wolf algorithm, the distance measurement precision is effectively improved. Compared with a traditional impedance distance measurement method, the method can remarkably improve the distance measurement precision, and compared with a traveling wave distance measurement method, on the premise that the precision is guaranteed, the step of data acquisition is simplified, a traveling wave distance measurement device does not need to be additionally arranged, and therefore the method has the large advantage in the aspect of fault distance measurement.
