The hydropower station is a power station that converts the potential and kinetic energy of water into electrical energy. The hydropower station monitoring and protection system is an equipment system that comprehensively and systematically monitors, controls and protects this energy conversion process.
The main task of the monitoring and protection system of hydropower stations is to monitor and control the water transmission and power generation system, hydraulic mechanical equipment and systems, electrical equipment and systems, flood gates and hydraulic structures, etc., so as to ensure the safe, efficient and economic operation of hydropower stations.
1. The monitoring system of a hydropower station mainly includes the measurement system, signal system, operating system and adjustment system of the hydropower station. At present, computer systems are generally used to realize the monitoring of hydropower stations.
2. The protection system of a hydropower station mainly includes water system protection, mechanical equipment protection and electrical equipment protection, such as flooded station protection, unit overspeed protection, overtemperature protection, low oil pressure protection for oil pressure device accidents, and relay protection for electrical equipment.
