[Introduction] The real-time monitoring and regular inspection for the primary electrical equipment in valve hall is extremely important to safety operation of converter station. [Method] In this study we investigated the demand of regular inspection of ±800 kV VSC-HVDC converter station, combined with the character of valve hall and operational experience in of converter station. [Result] The complete solution of intelligent inspection system in enclosed valve hall of ±800 kV VSC-HVDC converter station is provided. [Conclusion] Therefore, due to highly integrated of the proposed solutions, the automation level of inspection works will be increased dramatically.
