The utility model discloses a virtual anemometer tower system in wind -powered electricity generation field based on plateau mountain area wind turbine generator system, it includes the wind -powered electricity generation machine sensor unit in area certainly, and the wind -powered electricity generation machine is connected from the sensor unit and the quick -witted adc of wind -powered electricity generation in area, and wind -powered electricity generation machine adc and wind -powered electricity generation machine data acquisition and dispensing device are connected, and wind -powered electricity generation machine data acquisition and dispensing device are connected with the wind -powered electricity generation field receiving terminal of surveillance center, and wind -powered electricity generation field receiving terminal of surveillance center and the wind -powered electricity generation field sensor unit 0 of surveillance center are connected, solved among the prior art with high costsly at plateau mountain area wind -powered electricity generation field installation anemometer tower, the dependence is poor between actually exerting oneself in the list anemometer tower's that arranges measuring wind data and wind -powered electricity generation field, results in only relying on an anemometer tower to be difficult to represent the wind regime of whole wind -powered electricity generation field, because the special geography in plateau mountain area and weather conditions result in anemometer tower to damage or fall the tower easily, or the icing lead to the fact the wind meter ware damage or short time work malfunctioning, result in technical problem such as the serious disappearance of anemometer tower data.
