额定风速的英文
rated wind speed
wind rating
例句与用法
- Any wind turbines need power control . we aim at capturing wind energy in below - rated wind speed as much as possible and limiting the aerodynamic power in above - rated wind speed
任何风力发电机都需要功率调节，其目的是在额定风速以下尽可能多的吸收风能，在额定风速以上限制其功率的输出。 - Some important conclusions , such as movement of some work conditions under the circumstances of cut - in wind speed 、 rated wind speed and extreme wind speed . verify the stall phenomenon that the blade produces when being too big because of angle of attack , are verified
验证风力发电机在切入风速、额定风速和极限风速工况下的运行情况,验证了叶片由于攻角过大时产生的失速现象等。 - Based on research of wind turbine aerodynamic characteristics , this paper analyzed various control methods for a pitch - controlled system of variable - speed and constant - frequency wind turbine at a wind velocity range higher or lower its speed rating respectively
摘要在风力机空气动力学特性分析的基础上，讨论了变速恒频风力机组变桨距机构在低于额定风速阶段和高于额定风速阶段的不同控制策略。 - He finds the pitch range after calculated the three important parameters through the bladed for windows software , then presents an optimized control strategy that regulate the pitch angle in terms of the wind speed . it must control the output power because the variational output power brings the variational loads . he confirms and optimizes the control strategy that the output power is the control target , the output power is divided into three parts
将功率作为系统控制的目标，将功率分成三段进行控制，在低风速区，载荷是有限的，以功率最大化作为控制目标；在额定风速附近，由于处在升力曲线斜率的变化点，功率变化较大，应尽快调整桨距角进入失速区工作，减少载荷的波动，该额定风速区的上下工作点要通过现场试验的手段来确定；在额定风速以上，使功率维持在额定输出，减少功率波动，并通过bladed软件的仿真计算对控制策略进行了验证。 - The main technological characteristics include not only the integrated optimizing design of variable speed and constant frequency , ensuring the wind turbines to adapt to diversified wind plants with different temperatures and geographical conditions , but also the maximum wind power captured at optimized tip speed ratio below the rated wind speed and security protection of constant power output above the rated wind speed by variable pitch regulation
