The increasing investment of power generation groups and enterprises in the new energy industry has led to a continuous growth in the number of power stations and installed capacity, which has brought challenges and difficulties to the operation and management. CYG ET has developed a monitoring system for PV power stations, which is based on the principles of intensive, process-driven, procedure-based, and standardized operations, and is designed with the concept of regional centralized management. With functions such as real-time data monitoring, equipment control, parameter adjustment, and data uploading of PV power stations, the system not only meets the needs of enterprises for panoramic operation monitoring of power stations, comprehensive statistical analysis, intelligent fault diagnosis, and scientific production management, but also caters to the requirements of power supply companies’ dispatchers for operation evaluation and management assessment of power stations.
