【摘要】 针对经典PID变桨距控制器超调量大、波动剧烈等缺陷,提出了一种采用模糊PI控制与前馈控制相结合的控制器来控制浆距角,进而使机组功率稳定在额定功率附近的控制思路。通过对某1.5MW风力发电机组进行仿真,结果表明,该控制器控制效果优于经典PID变桨距控制器。更多还原

【Abstract】 Aiming at overshoot volume,volatility and other defects of classical PID pitch controller,a fuzzy-PI controller combined with feed forward controller was proposed to control the pitch angle,and thus to control the power.Simulation results on a 1500 kW variable pitch wind turbine showed that the new pitch controller was better than classical PID pitch controller.更多还原
