Analysis and Research on Integrated Construction of Digital Ultra-high Voltage Substation Based on Infrastructure Stage

As a new type of scheme, analysis and research are carried out to fully implement the Top-Level Design Plan for Digital UHV (ultra-high voltage, UHV) Substation and integrate the construction of digital UHV substation into the substation infrastructure stage. This topic discusses the overall design scheme of digital UHV substation according to the Top-Level Design Scheme of Digital UHV Substation and forms the following conclusions: (1) Digital UHV substation can improve the quality and efficiency of equipment monitoring, enhance the digital support capability of field operation, enrich the means of shift management, and improve the level of equipment early warning and decision-making, so it is necessary to build it comprehensively. (2) In order to avoid unnecessary investment, realize technical and economic synergy, enhance construction standardization, and improve the operation and management level of the UHV substation, the construction of digital UHV station can be included in the infrastructure stage for overall consideration.
