The Planning And Design Of Distribution Automation System In Xiangzhou Area

In recent years, the rapid development of the domestic economy and the increasing ofpower load, higher requirements on power quality of distribution power grid is put forward,power supply quality of city power grid has become the focus of people. Transformation ofthe city power grid so that the reliability of power supply10kV and below power distributionpower grid has been greatly improved, but the power grid complexity is also significantlyimproved. In order to every target in complex distribution power grid to improve the overalloperation of distribution power grid, distribution automation becomes imminent.Firstly, distribution power grid construction in Zhuhai District of Xiangzhou wereanalyzed, emphatically carries on the analysis to the Xiangzhou area typical distributionstructure and atypical distribution structure, provides an evidence for the implementation ofdistribution automation. Secondly, impact on the development of distribution automationsecondary system is analyzed, and combining the system with photovoltaic powerrequirements for the automation of access to the real communication and relay protection areanalyzed and explained in detail. Finally, according to the power grid reconfiguration ofdistribution model for distribution automation was studied in this paper, combined withpractical engineering analysis respectively on the cable and overhead line two kind ofautomatic device. Among them, the cable automation focuses on ring power grid cabinetrenovation, installation of overhead line automation focuses on watchdog. Based on the abovestudy, proposes the construction scheme of the different characteristics and the optimalscheme. Through the analysis of the distribution power grid automation of the Hengqin smartgrid, technology standard of the corresponding automation construction is get.The implementation of this study can guide the construction of distribution automationsystem, it has the important meaning of strengthening the construction of distributedgeneration access to distribution power grid.
