风力发电机组变桨距系统的分析与测试

Analysis and Testing of Pitch System of Wind Turbine

风力发电机组变桨距系统按动力分为液压变桨距系统和电动变桨距系统,对这两种变桨距系统分别进行了介绍,并进行了优缺点比较。以液压变桨距系统为例,提出一种采用有源液压测试站的风力发电机组变桨距系统测试方法。介绍了有源液压测试站的结构和原理,给出了测试准备工作及具体测试步骤。

The pitch system of wind turbine is divided into hydraulic pitch system and electric pitch system according to the power.The two pitch systems were introduced respectively,and their advantages and disadvantages were compared.Taking the hydraulic pitch system as an example,a test method for the pitch system of wind turbine using an active hydraulic testing station was proposed.The structure and principle of the active hydraulic testing station were introduced,and the test preparations and specific test procedures were given.
