I. Industry Background and Evolutionary Trends

Substations serve as critical hubs of the power grid, where operational efficiency and safety levels directly impact the stability of power supply across the entire region. As digital upgrades to the power grid progress, the traditional manual inspection model is gradually transitioning toward intelligent and automated operation and maintenance (O&M). By utilizing various online monitoring, remote control, and intelligent early-warning systems, integrated management and control of all substation equipment are achieved. This not only improves O&M precision but also significantly reduces safety risks.

II. Core System: Unified Monitoring Platform for the Entire Station

The core of intelligent O&M is the construction of a unified monitoring platform for the entire station. This platform integrates operational data from high-voltage switches, transformers, busbars, grounding devices, reactive power compensation devices, and auxiliary systems. It enables real-time collection and visual display of parameters such as voltage, current, temperature, switch status, and insulation performance. The background system automatically compares this data against rated indicators; if an anomaly occurs, it immediately issues graded alerts. This allows O&M personnel to grasp the operational status of the entire station without being on-site, effectively reducing inspection blind spots and manual oversights.

III. Multidimensional Monitoring: Key Areas and Equipment Safety Scenarios

Targeting critical areas and equipment within the station, intelligent monitoring methods cover a variety of safety scenarios:

Switching Equipment: Real-time monitoring of insulation defects through partial discharge sensors to detect discharge hazards in advance.

Temperature Rise Management: Installation of temperature monitoring devices on busbars and joints to avoid overheating failures caused by poor contact.

Auxiliary Environment: Environmental monitoring systems track temperature, humidity, harmful gases, and water accumulation in real-time. These systems link with dehumidification, ventilation, and fire protection equipment for automatic adjustment to ensure the operating environment meets standards.

Intelligent Security: Intelligent video analysis can identify illegal intrusions or abnormal equipment displacement, achieving the integration of security and equipment monitoring.

IV. Standardized Control: Standardized O&M and Error-Prevention Procedures

Regarding safety control, substations must still strictly implement standardized O&M processes on the foundation of intelligence:

Equipment Calibration: Regularly verify intelligent sensors, communication modules, and measurement/control devices to ensure accurate data transmission and reliable command execution.

Error-Prevention Operations: During switching operations, strictly follow error-prevention interlocking logic to eliminate accidents such as short circuits or grounding caused by human error.

Special Weather Response: For extreme weather such as thunderstorms, high temperatures, or cold waves, initiate specialized early-warning plans in advance. Conduct comprehensive inspections of lightning protection, heat dissipation, and anti-freeze facilities to ensure uninterrupted power supply under extreme conditions.

V. Emergency Linkage: Enhancing Anti-Risk Capabilities

A substation's emergency response system must also be linked with intelligent systems. When a fault occurs, the monitoring platform can quickly locate the fault point, determine the fault type, and automatically push handling solutions to help O&M personnel shorten repair times. Regularly conducting joint emergency drills—combined with simulated faults—tests the response speed of the intelligent system and the coordination of personnel, further enhancing the overall risk resistance of the station.

Summary: Empowering overall O&M with intelligent technology, combined with standardized safety management, not only improves the economy and reliability of substation operations but also drives the power grid toward a more efficient, safer, and smarter future, providing a solid guarantee for continuous and stable power supply.
