摘　　要：在“碳达峰、碳中和”的目标下,清洁可再生能源占所有能源的比重将越来越大,其中风力发电作为成熟的技术之一扮演重要的角色。为解决风电场可靠地并入电网,实现清洁能源远距离输送和优势资源互补,提出风电场接入系统方案细化。通过一次接入方案中增加承载力计算风能消纳、计及储能的短路电流、新能源多场站短路比等计算和分析,减轻风电能源不稳定性对电网的影响,实现电网安全稳定运行,充分发挥风电清洁属性;最后将上海某陆上风电场接入系统作为应用实例。Under the goal of"carbon peak、carbon neutrality",the proportion of clean renewable energy in all energy will be increasing,of which wind power as one of the mature technologies plays an important role.In order to solve the problem of reliable integration of wind farms into the power grid,long-distance transmission of clean energy and complementary advantages of resources,a detailed scheme of wind farm access system is proposed.Through the calculation and analysis of wind energy absorption,short-circuit current including energy storage and short-circuit ratio of new energy multiple stations by increasing the bearing capacity in the single-access scheme,the influence of wind energy instability on the power grid is reduced,the power grid is safe and stable operation,and the clean attribute of wind power is fully utilized.Finally,an onshore wind farm access system in Shanghai is taken as an application example.
