摘要
超级电容已成为现今主流的变桨系统后备电源。本文以超级电容为例,针对风电机组变桨系统后备电源设计,提出一种基于叶片载荷的能量计算方法。通过与传统顺桨能量计算方法对比发现,本方法能提高能量计算的准确度,实现成本优化,对变桨系统整体设计具有指导意义。
Ultra-capacitor has become the mainstream backup power supply of pitch system.Taking ultra-capacitor as an example,this paper proposes an energy calculation method based on blade load for the design of backup power supply of wind turbine pitch system.Compared with the traditional calculation method of feathering energy,the proposed method improves the accuracy,reduces the cost and proposes a guideline for the design of the pitch system.
