基于风电机组大部件温度的风电场能量管理优化

Energy Management Optimization of Wind Farm Aiming at Temperature Control of Wind Turbine Large Components

风力发电场中每台机组的健康状态不同,健康状态较差的风电机组在运行时会因部件温度高而出现停机现象。采用部件温度预测和部件劣化度计算的方法协调控制风电场内风电机组的发电功率,可有效控制部件温度超过报警值现象。该方法可平衡每台机组健康状态,进而提高整场发电量。

There usually exist individual differences of health status among the turbines in a wind farm,and wind turbines with poor health status may encounter shutdown due to high component temperatures during operation.This paper adopts the method of component temperature prediction and component deterioration degree calculation to coordinate and control individual power outputs of wind turbines,which can effectively avoid over-alarm-threshold temperature of turbine components.This method can balance individual health status of turbines,and thereby increase overall power generation of the wind farm.
