Fault location of measurement and control area based on universal gravitation search algorithm

When the distribution network fails, the operation and maintenance personnel need to quickly determine the fault location and minimize the scope of the inspection line so that the fault repair personnel can accurately reach the vicinity of the fault point to carry out work. Whether the fault location method is advanced and reliable directly affects the power failure time of the power supply user, and further affects the social, economic, and life aspects. Therefore, the fault location of the distribution network needs to satisfy both reliability and accuracy. It is the basis and premise for troubleshooting, isolating and restoring the power supply. Fault location of distribution network has important research significance. The universal gravitation search algorithm is used to locate faults in the non-measurement and control area of the distribution network, and the intelligent algorithm that meets the requirements of rapid positioning, accuracy and fault tolerance can improve the fault location efficiency.
