A Synaptic Plasticity-Based Fault Location Method for SNP System Containing Distributed Power Distribution Network

Abstract

The invention relates to a fault location method of a distributed generation including power distribution network of a synaptic plasticity based SNP system. The fault location method comprises the following steps of (1), selecting a power cut interval; (2), establishing a fault location model of the distributed generation including power distribution network of the synaptic plasticity based SNP system; (3), determining a fault section; according to fault information and a forward synaptic matrix which are read by the system, carrying out operation on the established fault location model; (4),verifying fault location accuracy; according to a fault location result obtained by a reasoning algorithm and the value of a sequential pulse train in a bidirectional functional neuron O, verifying the accuracy of the fault location result by combining an actual current matrix C and the reasoning algorithm; and (5), completing the fault location and the verification of the fault location accuracythrough a fault judgment standard and a fault current information verification standard. The fault location method of the distributed generation including power distribution network of the synaptic plasticity based SNP system, which is provided by the invention, has high accuracy and high reliability, and can be widely applied to the fault location of the distributed generation including power distribution network.

Description

technical field [0001] The invention belongs to the field of electric energy measurement, in particular to a method for fault location of a distributed power distribution network in a SNP system based on synaptic plasticity. Background technique [0002] Membrane computing (P system) is a new branch of natural computing, aiming to abstract computing models from the structure and function of living cells and from the collaboration of cell groups such as tissues and organs, and obtain new computing systems. The P system not only introduces new distributed parallel information processing methods and technologies for many fields, but also provides new tools for modeling and simulation of biological systems. research hotspots. The P-system is a distributed parallel computing model with good comprehension and dynamics, which consists of three parts: the hierarchical structure of the membrane, the multiset of representation objects, and the evolution rules.
