Operational characteristics of a large wind-farm utility system with a controllable AC/DC/AC interface

The design and operational issues associated with the interconnection of windfarms using a controllable AC/DC/AC series-connected interface are explored. The study considers steady-state operation and transient effects for both the power network and the wind system. The performance of rectifiers and converters is discussed, and computer simulation results are shown. Overvoltages created within the inverter stations and protection against short circuits are discussed.<
