Research on Technical Key, Difficulty and Solution of Smart Distribution Substation

    Introduction   The paper aims to establish a favorably operating environment, improve the reliability of power supply and operation and maintenance efficiency, and construct a safe, reliable, efficient and self-healing smart distribution station.

    Methods   In this paper, a large number of distribution station environment and maintenance problems were statistically analysed, and put forward the necessity of the constructing smart distribution station, and developed the technical route of the construction of smart distribution station on the basis of full investigation of monitoring equipment technology, then summarized the technical difficulties encountered in the promotion and construction of smart distribution station, made further research of pilot operation analysis of the project with the relevant equipment manufacturers, using micro-positive pressure ventilation technology, passive wireless sensor detection technology, intelligent linkage and remote control technology, artificial intelligence technology based on image recognition, installation of key sensors to achieve non-processing, non-damage and other advanced technologies.

    Result   The results we solved the key technical points and difficulties of circulating ventilation, eliminating dew point, creating intelligent operation and maintenance scenes and monitoring equipment status of smart distribution station, then satisfied the construction requirements of no manual operation and maintenance, no power failure installation and no influence.

    Conclusion   The solution proposed is not only included in the standard technical document of smart distribution station, but also extensive used in the construction of smart distribution station.
