摘要
本文主要讨论增量式和绝对式旋转光电编码器如何在风电控制系统中准确测量变桨电机转子旋转速度和位置。以及双馈发电机转子转速的精确测量,实现对桨叶角度控制和双馈发电机的伺服控制。
This paper discusses the methods of using incremental and absolute photoelectric encoders to measure precisely the rotor speed and position of the generator with variable pitch blades and the rotor speed of a double-feedback generator in the wind power generation control system so realizes the blade angle control and the servo control of the double-feedback generator.
