Abstract: Under the background of "dual carbon", China's installed capacity of wind power and photovoltaic ranks first in the world. New energy power station equipment is scattered, the number is large, the operation and maintenance is difficult, high-level operation and maintenance technicians are scarce, and the construction of centralized operation and maintenance system to improve the level of intensification is the only way. Based on the real-time/historical second-level massive data of the station, new energy intelligent operation and maintenance platform intelligent monitoring system has researched and developed real-time status monitoring tools such as long-stop, frequency cutting, inefficiency, communication interruption, line disconnection, etc., intelligent fault alarm monitoring tools such as repetitive faults and effective faults, and intelligent analysis and monitoring tools such as KPI indicator early warning and equipment operation performance, which has opened up the group and regional operation and maintenance platforms, and the monitoring indicators and data sharing of platforms at all levels to help operation and maintenance personnel improve monitoring efficiency and operation and maintenance level.
