【摘要】：针对风电并网功率波动性及高渗透弃风现象,采用共直流母线主动型永磁直驱风电机组结构,建立基于氢储能的永磁直驱风电机组模型,并提出变流器与功率管理协调控制策略。永磁同步发电机与电解槽、燃料电池、蓄电池组汇集直流母线,考虑电解槽需电制氢、燃料电池需氢发电等特性,利用变流器协调控制及功率管理策略,实现风电功率波动抑制、降低风电弃风比例、风电绿色并网。通过PMCAD/EMTDC仿真平台,证明了模型及其控制策略的有效性,有利于风电高渗透并网运行。
[Abstract]:In view of the fluctuation of wind power and the phenomenon of high permeable wind rejection, a permanent magnet direct drive wind turbine model based on hydrogen storage is established by using the common DC bus active permanent magnet direct drive wind turbine. The coordinated control strategy of converter and power management is put forward. Permanent magnet synchronous generator and electrolytic cell, fuel cell and battery group gather DC bus, considering the characteristics of electrolysis cell to produce hydrogen, fuel cell to need hydrogen to generate electricity, etc. By using the coordinated control and power management strategy of the converter, the wind power fluctuation is restrained, the wind power ratio is reduced, and the wind power is connected to the grid. The effectiveness of the model and its control strategy is proved by the PMCAD/EMTDC simulation platform. It is favorable to wind power high permeability and grid operation.
