Collection schemes based on DC technologies appear as a possible alternative to present layouts of offshore wind farms to reduce the installation and operational costs. Within these internal DC collection schemes, series connection can be particularly attractive when a sufficiently high number of units are cascaded in order to reach a voltage level suitable for direct HVDC transmission. Power electronics...
As the wind power generation technique is improved greatly, permanent magnet synchronous generator (PMSG) is paid more and more attention because of its multiple advantages. Nevertheless, conventional directly-drive PMSG wind generation system is connected to the grid by AC transmission. This paper introduces the DC connection structure of wind farm based on PMSG. According to VSC-HVDC (Voltage Source...
