摘要
风力发电作为当前发展比较成熟的清洁能源,风电机组规模数量以及装机容量均不断提高,容量已经达到兆瓦级。但风能的特殊性导致风电场可控性较差,在并网过程中必须对风机采取相应的控制手段来保障风电机组脱网运行。如果脱网运行过程中出现故障,将会产生更严重的、大范围的二次危害,甚至引发大型事故。文章主要针对风力发电机组的高电压穿越技术进行研究,解析风力发电机组高电压穿越技术发展现状,分析我国电网中常用的电力发电机组高电压穿越技术,提出具有优良应用性能的风力发电机组并网点电压控制的高电压穿越技术方案。
As a relatively mature clean energy,wind power generation continues to increase the scale,number and installed capacity of wind turbines,with the capacity reaching MW(megawatt),but it faces a lot of problems in the development of wind turbines.Due to the particularity of wind energy,the controllability of wind farm is poor.In the process of grid connection,corresponding control measures must be taken for the wind turbine to ensure the off grid operation of wind turbine.If there is a fault in the off grid operation,it will produce more serious large-scale secondary hazards and even lead to large-scale accidents.This paper mainly studies the high-voltage ride through technology of wind turbine,analyzes the development status of high-voltage ride through technology of wind turbine,analyzes the high-voltage ride through technology of power turbine commonly used in China's power grid,and puts forward the highvoltage ride through technology scheme of parallel node voltage control of wind turbine with excellent application performance.
