Recently, the ±500kV Huaxin converter station's digital team system platform was put into online application. The UHV branch of State Grid Shanghai Electric Power Company took the lead in building a professional DC digital team in the State Grid Co., Ltd. system to reduce the burden of the team, improve quality and efficiency, and promote the digital transformation of equipment management.

In accordance with the work deployment of the company's construction equipment operation inspection digital team, the State Grid Hai UHV Company started the digital team construction pilot work at the Huaxin converter station. According to statistics, since the trial operation of the digital team system platform in October, the manual copying and filling in the operation and maintenance work of Huaxin converter station has been reduced from the original 32 items to 13 items; the ledger record book has been reduced from 45 to 5; The equipment data in the station realizes real-time return, from the original two entries to one entry; the equipment spare parts realize dynamic management, reducing the preparation time of the production operation by 32%; through the real-time comparison of daily inspections and standardized inspections, inspection efficiency An increase of 45%.

During the construction of the digital team system platform, the State Grid Hai UHV Company adheres to the problem-oriented approach, focuses on practical applications, takes equipment as the core, based on professional characteristics, and focuses on the normal business and core business of the team, and has successively completed the software development and design of the system platform, and the hardware Equipment installation and commissioning, network equipment configuration and security policy setting, equipment data docking and input, etc., integrate three-dimensional modeling, data sharing and other technologies with converter station routine inspections, safety management and control, and ledger management to integrate data "Multiple connections", "multiple sharing", and "multiple running paths", so as to realize the visualization, mobilization and onlineization of operation and maintenance work, and improve work efficiency. The company will improve the application modules in the system platform, optimize the operation and maintenance management model, and form a replicable and popularized digital team construction and application case as soon as possible.
