Short circuit fault location technology in substation area based on"edge-terminal coordination"architecture
Aiming at the requirement of accurate fault location in low-voltage substation area of new power system,a low-voltage substation area short circuit fault location technology based on"edge-terminal coordination"architecture was developed.Firstly,the architecture of the internet of things(IoT)in the substation area for multi-level short circuit fault location was proposed;Secondly,a detection method for short circuit fault of IoT terminals at all levels in the station area using the second-order least square fitting algorithm was studied;Thirdly,a fault location communication protocol based on HPLC communication was also designed.For intelligent distribution transformer terminals,a short circuit fault location strategy based on substation topology was proposed,and edge computing and its hardware technology were implemented.On this basis,the validity of the"edge-terminal coordination"IoT platform area short circuit fault location technology was verified through the real low-voltage AC system short circuit fault test experiment.
