Dynamic planning and positioning method for power distribution network faults

Abstract

The invention provides a dynamic planning and positioning method for power distribution network faults, which is characterized by adopting causal analysis to establish an incidence relation model between automation equipment monitoring information and feeder line states, and constructing a power distribution network fault positioning mathematical model; performing state reduction on a combined optimization problem by combining an inclusion-exclusion principle; and performing fault positioning through evaluation function calculation and non-fault section search. The dynamic planning and positioning method of the invention has the beneficial effects of solving the problem of complex fault positioning space of a power distribution network, performing state reduction on the combined optimization problem by combining the inclusion-exclusion principle, reducing the overlapping of sub-problems, reducing repeated calculation and improving a calculation speed.

Description

technical field [0001] The invention relates to the technical field of electric power systems, and more specifically relates to a dynamic planning and positioning method for distribution network faults. Background technique [0002] With the continuous improvement of peoples living standards, users have higher and higher requirements for power supply quality and reliability. Once a power distribution system fault occurs, fast and accurate analysis, location and isolation of faults are extremely important for minimizing power supply interruptions to users and improving power supply security and reliability. Distribution network fault location is one of the important functions of distribution automation. When a fault occurs in the distribution network, the fault location can be quickly found through the fault location function, which provides effective guidance for isolating faults and restoring power supply to users as soon as possible, which is of great significance for imp...
