With the large‑scale development of onshore wind power, the traditional on‑site duty mode for individual wind farms is gradually transitioning to remote centralized monitoring through regional centralized control. In mountain wind farms, collector cables are extensively buried, and lightning‑induced trips are frequent during thunderstorm seasons. Fault locations are concealed, making on‑site investigation and troubleshooting difficult. This places higher demands on centralized control operators in data analysis, fault diagnosis, and cross‑site coordination. Based on engineering practice in wind power operation and maintenance, this paper describes the construction of a regional centralized control center and the implementation of fault recorder data integration. It summarizes the diagnosis and handling procedures for typical faults of outgoing transmission lines and collector cables, presents the achievements in safety standardization of the centralized control system, analyzes existing deficiencies in current centralized control operation, and proposes targeted optimization measures. Practice shows that this mode can shorten the waiting time for fault analysis and improve the efficiency of cross‑site collaborative handling, providing a reference for the regional centralized control operation and management of similar mountain new energy stations.
