Title: Evaluation on Wind Power Resources of the Wind Power Plant in Yanshan Lake Area of Chaoyang County
Abstract: [Objective] The purpose was to study the situation of wind power resources of Yanshan Lake area in Chaoyang County of Liaoning province.[Method] The wind-measuring tower was set up on April,2006.The wind direction and velocity at the heights of 10,30 and 60 m were measured during 1 year.Parameters of wind power resources were calculated and analyzed in detail to evaluate the wind power resources of Yanshan Lake area in Chaoyang County.[Result] The corrected annual average wind velocities of Yanshan Lake wind power field at the tower heights of 60,30 and 10 m were 4.7,4.2 and 3.8 m/s resp,and the annual and monthly average wind velocities increased along with the increment of height.Yanshan Lake wind power field took WSW wind as dominant wind direction,with occurrence frequency of 13%;the next was NW wind with occurrence frequency of 10%~12%,and the wind leaning to S was dominant energy wind direction.The occurrence frequency of wind velocity of 3 m/s was highest at tower height of 60 m,and that of wind velocity of 2 m/s was highest at tower height of 30 and 10 m.All the wind velocity changes of each gradient were shown as single peak type,with maximum wind velocity at 10:00~20:00 and minimum wind velocity at 4:00~8:00.The measured effective wind power hours of 3~25 m/s at tower height of 60 m was over 5 151 h,with annual average density of wind power being over 140 W/m2.[Conclusion] The wind power resources of Yanshan Lake area was richer and suitable to build wind power field,and had some value in exploitation and use.
