The invention discloses a wind power plant voltage support control method and system based on power injection priority, and relates to the technical field of offshore wind power generation. Establishing a power injection priority optimization model by taking transient voltage support requirements, wind driven generator output power limitation and converter capacity limitation as constraint conditions and taking maximization of reactive power injection power of a wind power plant and minimization of active power drop of the wind power plant as optimization targets; and obtaining active/reactive power injection strategies of the wind driven generator under different operation conditions by adopting a power injection priority optimization model according to the operation data of the wind power plant so as to control the operation of the wind power plant. Frequency oscillation caused by voltage drop is reduced, and transient frequency stability of the system is improved. 本发明公开一种基于功率注入优先级的风电场电压支撑控制方法及系统，涉及海上风力发电技术
