摘要
变桨系统及其后备电源是大型变速变桨距风电机组的关键组成部分.对风电机组的安全运行具有十分重要的作用。本文探讨了大型风电机组变桨系统备用电源的几种方案.对各种备用电源进行简单对比分析。本文还以中国南车的WT2000D110型风电机组变桨系统为例。
Pitch system and its backup power is the main part of a large variable speed variable pitch wind turbine generator system, has a very important role on the security operation of wind turbine generator. This paper discusses several schemes of the backup power system, makes a comparative analysis to the several energy storage units of backup power system.According to the WT2000D110 type wind turbine generator system of CSR, ultracapacitor and its application in the pitch system is introduced.
