In order to effectively solve the large number of data problems existing in the use of new energy big data platform, power generation enterprises need to organize and carry out effective data governance. For power generation enterprises to establish a new energy enterprise large data centers in wind power value to data mining, data quality raise and manage data governance problems in the implementation process, put forward a kind of wind data management system based on data standardization, the core content, including data standard, data quality management, the whole process of cycle management, data security, etc. The system has been deployed and implemented in the new energy monitoring and big data center of China Datang group. Through the data standardization work, a complete data governance platform and auxiliary support measures (systems, management norms and technical standards) have been formed to effectively improve the group's new energy monitoring and big data center wind power data quality. It can provide reference for data governance of other enterprise-level new energy data centers.
