Renovation Scheme for Unattended Automatic System of Hydropower Station
The core of the transformation of the unattended automation system for hydropower stations is to upgrade the traditional manually attended power station into a modern intelligent power station with "unattended operation and minimal personnel on duty" through computerized monitoring, intelligent sensing, reliable communication and remote centralized control. It realizes remote monitoring, automatic control, fault self-diagnosis and safety early warning, greatly reducing labor costs and improving operational efficiency and safety. Among them, the secondary electrical system, as the "nervous system, brain and safety line of defense" of the power station, is the core support for the unattended transformation. Without a reliable secondary system, true unattended operation cannot be achieved. Therefore, this integration will focus on improving the detailed content of secondary electrical equipment while retaining the full process details of the transformation.

Ground Distance Protection (21G)
Differences Between Phase-to-Phase Distance Protection (21P) and Ground Distance Protection (21G)
The core difference between phase-to-phase distance protection and ground distance protection lies in the selection of measured quantities, fault response range, and connection methods. They complement each other to form a complete distance protection system for high-voltage transmission lines, both following the basic principle: operation if the measured impedance is less than the setting impedance.
