According to the analysis of industry research institutions, the market space of China’s smart substation online monitoring system from 2020 to 2025 is about 54 billion yuan, and digital twin technology has become the core technical support for smart substation construction [1].

Siyuan Electric’s layout characteristics in this field:

• Continuous Increase in R&D Investment
  : In 2023, the company’s R&D expenses reached 917 million yuan, a year-on-year increase of 36.20% [0]
• Intelligent Upgrading of Products
  : The Super5000 Monitoring and Intelligent Operation and Maintenance System has completed customer inspection and mass production and sales
• Technological Innovation Capability
  : As of June 2025, the company has a total of 948 authorized patents, including 342 invention patents

Siyuan Electric has formed a relatively complete product system and technical accumulation in the application of digital twin technology, which is mainly applied to:

1. Comprehensive Monitoring of Smart Substations (Super5001 Platform)
2. Online Monitoring and Diagnosis of Equipment Status
3. Remote Intelligent Operation and Maintenance and Decision Support
4. Digital Management of Full Life Cycle of Equipment

With the in-depth advancement of the construction of new power systems and the digital transformation of power grids, the application of digital twin technology in the power equipment field will continue to deepen, and Siyuan Electric is expected to continue to benefit from its technical accumulation and market layout.
