摘要

Abstract

With the expansion of offshore wind farms (OWF)

attention has been paid to the voltage stability of wind turbines (WT) in the scenario of island operation mode. Excessive terminal voltage in a few WTs due to terminal voltage distribution will reduce their power generation efficiency or potentially lead to a trip. A calculation methodology for OWFs' single-cable layout boundary is proposed in this paper to optimize the number of WTs connected to a single cable. Enforcing the layout boundary can improve the WTs' terminal-voltage stability and prevent degradation of power generation efficiency. First

the terminal-voltage function is constructed based on the power flow of the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\pi$-type cable

and the terminal-voltage distribution within WTs connected to the single cable is revealed. Second

in several grid-connected voltage scenarios

the terminal voltage boundaries are set to limit the number of WTs connected to a single cable. Case studies built in MATLAB are carried out to verify the performance of the proposed terminal voltage boundaries. OWFs' single cable layout boundary can effectively evaluate the terminal voltage stability of WTs in current OWFs and guide the layout planning of upcoming wind farms.
