Discussion on Configuration of Emergency Power Source for Wind Turbines
Wind turbines losing power supply can not reduce wind pressure by adjusting blades'windward angle,and thereby face risks of excessive-wind-pressure-induced blade fracture and large economic losses.In order to reduce losses,it is necessary to consider emergency sources to improve the reliability and safety of wind turbine operation.In this paper,three schemes of emergency source configuration have been proposed.Through technical and economic comparison,the safe and reliable scheme with the simplest distribution system wiring and the lowest operating cost has been determined.
