摘要: |
在分析双功率流风力发电系统的工作原理及数学模型基础上,提出了基于此系统的2种变速变桨距功率控制策略,分别为功率PID变桨距及叶尖速比最大风能跟踪功率控制策略和转速PID变桨距及电流给定最大风能跟踪功率控制策略。分别建立了这2种功率控制策略的仿真模型,同时通过仿真比较了这2种控制策略的优缺点。仿真结果表明转速PID变桨距及电流给定最大风能跟踪功率控制策略控制相对简单,功率输出平稳,更适用于该新型双功率流风力发电系统。 |

Abstract: |
The working principle and mathematical model of DPF-WECS(Dual Power Flow Wind Energy Con-version System) are analyzed and two variable-speed variable-pitch power control strategies are proposed:the power PID pitch control with TSR-MPPT(Tip Speed Ratio Maximum Power Point Tracking) and the rotor-speed PID pitch control with CG-MPPT(Current Given MPPT). Two simulation models are built respectively and two power control strategies are compared. Simulative results show that,the latter is simpler in imple-mentation,more stable in power output and more suitable for DPF-WECS. |
