doi:10.11930/j.issn.1004-9649.202002025

Abstract

Abstract: For techno-economic comparison between the scheme of 66 kV AC collection system of offshore wind power connected directly to converter station and the traditional scheme of 35 kV collection system connected to converter station through a 220 kV booster station and 220 kV cables, an offshore wind farm in South China Sea is chosen for a case study. The two connection schemes of the wind farm are compared in terms of power loss, primary electrical equipment investment, and others. It is concluded that the 66 kV AC connection scheme is better in economic benefit. Along with the development of offshore wind farms in China, the 66 kV AC connection scheme has very good technical advantages in reducing the construction cost of VSC-HVDC system for offshore wind power and promoting innovation of technologies.

Key words: offshore wind farm, VSC-HVDC, 66 kV connection, offshore inverter station, techno-economic analysis
