Distribution automation system is an important tool to ensure the safe and reliable operation of the power distribution network. With the increasing popularity of distribution automation system, more and more of the distribution automation system has been put into operation, but comprehensive evaluation on the operation of the power distribution automation is rarely studied. Combined with analytic hierarchy process and fuzzy evaluation method, the comprehensive evaluation system for urban distribution automation system is established by the analysis of distribution automation operation evaluation indicators, and operation of distribution automation is evaluated from the three aspects of master station, distribution terminal and communication network. Actual statistical data from a power distribution automation system in Tianjin is analyzed. The results show that the method can reflect the real distribution automation operation, can be used as distribution automation operation practical evaluation means and operation and maintenance.
