| description | The invention discloses an active power distribution network fault section positioning method and system. The method comprises the following steps: acquiring switch fault actual current information and a section line actual operation state; converting the actual operation state of the section line associated with the switch into corresponding switch fault prediction current information by adopting the constructed switch function; and adopting the constructed evaluation function to determine the fitness value of the section line according to the corresponding switch fault prediction current information and the switch fault actual current information, so as to determine the section line with the switch fault, thereby positioning the position of the fault section. And a switching function for the active power distribution network is constructed, and an evaluation function is constructed based on a fitness function of a hybrid optimization algorithm, so that the accuracy, rapidity and fault tolerance of fault sec |
