Analysis and Prospects of Offshore AC Substation Design Technology

Abstract

As a connecting hub of offshore wind farms and onshore power network, the economics and reliability of offshore substation determines the performance of the offshore wind project. While the offshore substation is the platform where numerous high voltage devices first installed and operated in the ocean, there are some differences of designing offshore substation and onshore ones. This paper analyzed the differentia of onshore and offshore substation design technology. Besides, the state of art of key technologies of electrical system and maintenance were reviewed and the new techniques were highlighted in this paper.
