为了进一步提高日本的风力发电总装机容量，迫切需要减少并网风力发电系统的功率输出波动。本研究的重点是限制最大电功率输出，通过改变设定点的功率输出控制作为一种减少技术。利用实测风场资料，通过数值模拟，分析了限制2MW系统最大输出功率对变速运行系统输出功率波动特性的影响。重点是功率输出波动，这是重要的商业电力系统，包括发电厂，2兆瓦的系统的最大电功率输出的六种情况下的管理。结果表明，在高风速下，限制最大输出功率不会影响桨距角运行时的输出功率波动特性和控制性能。然而，全年模拟表明，限制最大电力输出带来了减少电力输出波动和发电性能之间的权衡。
The reduction in the power output fluctuation of grid-connected wind turbine-generator systems is strongly required to further increase their total installed capacity in Japan. This study focuses on limiting the maximum electric power output by changing the set point of the power output control as a reduction technique. The influence of limiting the maximum electric power output of a 2 MW-system, which adopts the variable speed operation, on the power output fluctuation characteristic is analyzed through numerical simulation conducted by using an observed field wind data. The focus is on the power output fluctuation, which is important for management of commercial power systems including power plants, of the 2 MW-system with six cases of the maximum electric power output. The results show that limiting the maximum electric power output does not have an influence on the power output fluctuation characteristic and control performance during the pitch angle operation at high wind speeds. However, the year-round simulation reveals that limiting the maximum electric power output brings a tradeoff between the reduction in the power output fluctuation and the generating performance.
