摘要:
探讨了交流励磁变速恒频风力发电系统的运行原理,分析了并网前、后双馈异步风力发电机的运行特点和控制目标,研究了基于定子磁链定向矢量控制技术的发电机并网控制和最大风能追踪控制。采用分开建模、分时仿真的思路,建立了包括并网控制和风能追踪两大模块的交流励磁变速恒频风力发电仿真系统。两个模块包括不同的发电机模型和控制策略,通过分时工作和数据转移的方式完成并网前、后整个过程的系统仿真。完整的仿真研究验证了交流励磁变速恒频风力发电机建模及控制的正确性与有效性。 |

Abstract:
The function principle of AC-exited VSCF wind power generation system is discussed and the control task and run characteristic of doubly-fed asynchronous wind generator before and after grid-connection are analyzed in this paper. Grid-connection control and maximal wind power tracing control of generator are investigated based on stator field-oriented vector control technique. By modeling generator respectively and time-sharing simulation, the AC-exited VSCF wind power generation simulation system is founded, which includes two modules named grid-connection module and wind power tracing module. These modules in which generator model and control strategy are different can simulate the whole progress before and after grid-connection based on time-sharing and data-transferring method. Fully simulation verified the correctness and validity of the modeling and control of AC-exited VSCF wind power generator discussed in this paper. |
