Embodiment Construction
[0023] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] The invention discloses an accurate method for an overhead line of a distribution network based on a fault indicator. The method includes the following steps:
[0025] (1) Modeling the distribution network overhead primary equipment network;
[0026] (2) At least one fault indicator is installed on the line tower between the distribution network switch or adjacent switches, and the fault indicator monitors the feeder current in real time;
[0027] (3) Take the fault indicator as the secondary equipment, and carry out the association modeling with the primary equipment; set two attributes of "main equipment" and "auxiliary equipment" for each fault indicator to describe the correspondence between the fault indicator and the primary equipment relationship and installation location, the two attributes of the fault indicator "mai...
