0引言作为一种可再生清洁能源,风能越来越受到各国重视。与陆上风力发电相比,海上风速大且稳定,每年可利用小时数达到3 000h以上[1]。近几年我国海上风电发展速度非常迅猛,现已趋于高电压、大容量输电,并向远海延伸。虽然采用交流220kV线路传输400 MW容量的需求,已在我国多个海上
0 Introduction As a renewable clean energy, wind energy is more and more valued by all countries. Compared with onshore wind power, offshore wind speed is large and stable, with more than 3 000 hours of usable hours per year [1]. In recent years, the development speed of offshore wind power in our country is very rapid, and now it tends to be high-voltage and large-capacity power transmission and extends to the distant sea. Although the use of AC 220kV transmission line capacity of 400 MW demand, has been in many sea
