Abstract

Abstract:

The construction of offshore wind power is of great significance to the realization of the “dual carbon” goal and the construction of a new power system with new energy as the main body. Far away from land and complex sea conditions make the control, operation and maintenance (O&M) of offshore wind turbines face many challenges, which are key issues that must be taken seriously and solved in large-scale construction. This paper summarized the current development trend of offshore wind power and related research progress, analyzed the main problems faced by the control and O&M of offshore wind turbines, and sorted out the key technologies of offshore wind power from two aspects of intelligent control and intelligent O&M,so as to provide reference for carrying out frontier theoretical and technical research in this field.

Key words: offshore wind power, renewable energy, intelligent control, intelligent operation and maintenance
