风机超速问题应对策略研究

文章针对大风大湍流下风机容易发生超速的问题,深入研究风机控制算法,提出了优化变桨PI和加入转差加速度系数的策略。Bladed仿真表明,加入超速应对策略后风机转速平稳,变桨响应较快,功率相对平稳且未发生停机,完全可以经受大风大湍流带来的冲击。实际应用该策略的FD77B和FD82B型风机运行情况良好,风机超速停机故障大幅下降。理论仿真和实际应用表明,该策略科学、合理、实用,且具有一定的推广价值。

Study on Coping Strategies for Wind Turbine Overspeed

For wind turbine overspeed problem in gale and grand turbulence,this paper studies deeply the wind turbine control algorithm,and proposes a strategy of optimizing the pitch PI and adding the speed difference acceleration coefficient.The Bladed simulating result shows that the wind turbine added coping strategies for wind turbine overspeed problem acts smoothly,rapid in pitch response,stable in power output and without shutdown,and can withstand the impact of gale and grand turbulence.The wind turbine adopted such strategy in FD77 B and FD82 B runs well,and the wind turbine overspeed fault is dropped significantly.Theoretical simulation and practical application results show that the strategy is scientific,reasonable,practical,and has some promotional value.
