The gate measurement and control system using wind-wind complementary DC power supply in water transmission projects has been experimentally applied in many domestic water transmission projects.The system uses direct DC drive for gate and valve monitoring.The systematic water transmission measurement and control scheme equipped with video monitoring,water situation monitoring,hydraulic monitoring and information transmission functions has been more mature and has the conditions for promotion and application.The new energy power supply and DC direct drive gate measurement and control scheme of the system can effectively solve the prominent problems existing in water conservancy projects such as high mains supply cost,large safety and environmental protection cost,and difficult management and maintenance,providing a basic guarantee for effectively promoting the construction of water conservancy information,providing technical support for the construction of smart water conservancy,and analyzing the characteristics of the DC gate measurement and control system of wind-solar complementary power supply.Through the actual system engineering construction and test operation,it shows that the gate measurement and control system of wind-wind complementary power supply can achieve stable operation requirements,and it is necessary to carry out targeted design and selection under specific environment and design configuration and use conditions.
