Creating an "Unmanned" Substation

Creating an "Unmanned" Substation

Substations are the core link of the power grid, but there are common issues in traditional operation and maintenance management processes:

  • Difficulty in real-time supervision: Daily inspections and maintenance operations cannot be supervised in real time, generally only allowing post-event playback to investigate causes, making supervision cumbersome.
  • Lack of visual management: Unable to understand the on-site operation status and equipment condition in real time, and unable to view and manage equipment information interactively.
  • Difficulty in event tracing: Multiple management systems are relatively independent, lacking correlation analysis, relying more on manual management on-site or in the backend.
  • No guarantee of work safety: Dangerous behaviors such as boundary crossing, entering restricted areas, and operational errors cannot be alerted in real time, and video surveillance utilization is low.
  • Low efficiency in information inquiry: Decision-making data is scattered, requiring queries across multiple systems to analyze fault causes when failures occur.
  • High intensity of inspection work: Large distances between stations, short patrol times, and high operational efficiency requirements result in high work intensity for operation and maintenance personnel.

To promote the construction of smart energy infrastructure and support new infrastructure, the construction of smart substations has become one of the key projects in the country's development of new infrastructure. Based on smart grids and energy IoT, supported by new technologies such as IoT, big data, 5G communication, artificial intelligence, and digital twins, the country is vigorously promoting the intelligent and digital transformation and upgrading of existing substations.
