Electrical Single-line Diagram Design of a 300 MW Offshore Wind Farm
-
Abstract
The paper consider a typical condition of the offshore wind farm project in China, which has a capacity of 300 MW, through a 220 kV line connected to the grid. The electrical single line diagram is discussed, then the paper presents the voltage of the offshore substation and the HV-submarine cable, the array cable topology and collector system switch configuration, the main transformer number, capacity and type selection scheme and the reactive power compensation scheme. The views on main problems of electrical design of offshore wind farm are proposed, which provide a reference for the electric design of offshore wind farm.
