中文摘要：

由于目前风电场出线容量整定计算时,标准风速远小于风机实际运行风速,造成了风场出线输送能力的浪费。文中提出了一种综合考虑风机出力特性和输电线路允许载流量变化特性的风电场出线增容方法。通过分析风机的风速功率曲线和输电线路最大载流量计算模型,将风机总功率和导线最大载流量在不同风速下进行动态匹配,以作为运行和设计中增容方案制定的基础。对于运行中的风电场,计算风机极限投运量;正在设计阶段中的风电场送出线路,降低所用导线的截面积。经实例分析,该方法有效增大了风电场的出线容量,提高了风电场运行经济性。

英文摘要：

Currently, the standard wind speed used for wind farm outgoing transmission line rating is much smaller than actual wind speed in operating environment, which has caused a huge waste of transition line capacity. A new rating method for wind farm outgoing transmission line based on combined consideration of wind turbine power characteristic and transmission line permissive carrying current characteristics is proposed. By dynamically matching the power curve of wind turbine and transmission line, the proposal of transmission line capacity improvement for operation and design is raised. For wind farm in operation, the maximum operating quantity is calculated; for wind farm in design, the cross-section of transmission line is decreased. An example has proved that, this method effectively increased wind farm outgoing transmission line capacity, and improved economic benefit of the wind farm.
