Research on Key Technologies and Design Applications of 220kV Intelligent Substation

This paper presents the design and application of a 220kV intelligent substation, focusing on system architecture, key technologies, and simulation-based performance validation. Sensor networks, Supervisory Control and Data Acquisition systems, and artificial intelligence-driven predictive maintenance are integrated to enhance operational efficiency. Simulation experiments validate the effectiveness of fault detection, load balancing, and energy optimization. Results demonstrate improved fault isolation times, reduced power losses, and enhanced grid reliability, proving the intelligent substation's role in modern power systems.
