Abstract Along with the social development needs, the power supply quality and reliability of distribution network power supply of the increasingly high demand. In recent years, State Grid Corporation of China gradually promotes the distribution automation construction, improve the distribution network automation. The rise of the construction of distribution automation, distribution automation equipment fixed value become more and more concerned about the topic. In this paper, distribution automation equipment how to set were discussed and studied, the voltage distribution automation terminal, boundary type distribution automation terminal equipment setting is analyzed in detail and tuning an algorithm is given and the reference value, so as to achieve the accurate, reasonable setting equipment protection value objective the distribution automation terminal, to realize fast fault isolation, reduce the power outage, increase the reliability of the power supply function, supply the reliable guarantee for the residents of production, life, to bring good economic benefits and social benefits for the company. Keywords: Distribution Automation; Protection; Setting Value
