摘要
Abstract
The distribution network has the characteristics of wide coverage,long total length of lines and complex structure,which leads to high probability of failure and difficulty in finding the fault location.It seriously affects the stability of the system and the relia-bility of power supply for users.Firstly,it proposes a method of distribution network fault section location based on Bayesian com-pressed sensing sparse current reconstruction.By analyzing the sparsity of virtual node current when the fault occurs,it controls the distribution network pressure measuring unit(PMU)device based on 0～1 integer programming method.Secondly,it establishes the distribution network node voltage underdetermined equation.It uses the Bayesian compressed sensing technology to solve the node sparse current vector,and then determines the fault section.Finanlly,it has the simulation analysis on IEEE 33-bus distribution net-work.The results show that this method has good positioning accuracy on the basis of ensuring the reliability of the results.关键词
