As the distribution network structure becomes more complex,the probability of distribution network failure is in-creasing.The traditional centralized master station and local distribution self-healing operation mode has its own advantages and deficiencies,and it is difficult to meet the requirements of high fault positioning accuracy and rapid fault isolation of the self-healing centrol requirements of the distribution network simultaneously.Based on the analysis of several typical free technolo-gies of distribution network,a self-healing control technology based on centralized master station and local distribution is put forward with the advantages of fast fault handling speed and high reliability,the distributed intelligent method can quickly cut off the fault point and determine the fault isolation range.It further reduces the isolation range,generates optimal processing strategy,restores load power supply and reduces the influence range of faults.The new integrated self-healing control strategy can improve the accuracy and timeliness of self-healing technology for distribution network fault processing.
