Purpose

Due to rising interest in wind energy harvesting offshore as well as in the urban environment, vertical axis wind turbines (VAWTs) have recently received renewed interest. Their omnidirectional ability makes them a very fascinating choice for use with the frequently varying wind directions. Therefore, the main concern is reducing vibration of the turbine blade as well as wind tower, self-starting at low wind speed, and stability issues at very high wind speed for VAWT.

Methods

In this paper presents a detailed overview of various pitch control configurations in VAWT to avoid vibration, self-starting problem w.r.t. wind speed.

Conclusion

Various research work carried out in this field has been studied critically and according to the number of blades choose effective pitch control mechanism to control the vibration and rotation speed of wind turbine.

各种垂直轴风力发电机的变桨控制机制：综述

目的

由于人们对海上和城市环境中风能收集的兴趣日益浓厚，垂直轴风力涡轮机 (VAWT) 最近重新受到关注。它们的全向能力使它们成为与频繁变化的风向一起使用的非常迷人的选择。因此，主要关注的是减少涡轮叶片和风塔的振动、低风速下的自启动以及 VAWT 在非常高的风速下的稳定性问题。

方法

在本文中，详细概述了 VAWT 中的各种变桨控制配置，以避免风速引起的振动、自启动问题。

结论

在该领域开展的各种研究工作已经进行了批判性研究，并根据叶片数量选择有效的桨距控制机构来控制风力涡轮机的振动和转速。
